Favorites/Bookmarks: Save verses for later reading or study. Responsive UI: Works smoothly on both mobile and desktop browsers
I need a cross-platform reminder application that runs smoothly on both iOS and Android. The core feature is hands-free use: I want to press one button, speak naturally—“remind me to drink water at 3 p.m.”—and have the app parse the command, schedule it, and confirm out loud or with a brief on-screen prompt. Think of the voice flow you experience with Alexa or Google Assistant; I’m after that same friction-free feel, but inside a dedicated app. Scope of the first release • Voice capture and speech-to-text using any reliable low-code or no-code tools you’re comfortable with (Flutterflow, Adalo, React Native with Expo Voice, etc.). • Time-based reminders only, with options for one-off or recurring schedules (daily, weekly, custom interval). ...
I’m expanding our mobile team and need a Flutter front-end developer who can take full ownership of the customer-facing side of a new e-commerce app. The work is 100 % Flutter, so solid Dart fundamentals and at least two years of hands-on experience are non-negotiable. You’ll be shaping every screen in line with our in-house Custom Design System, not off-the-shelf Material or Cupertino components, so an eye for detail and comfort with bespoke styling is essential. Scope of work You’ll turn Figma mock-ups into smooth, production-ready code, wire the UI to the REST endpoints our back-end team exposes, and make sure performance holds up across Android and iOS. While the app may later grow into social or utility features, your immediate focus is strictly e-commerce. Core ...
I’m ready to build and release a full-scale real-estate marketplace app on both Android (Google Play) and iOS (App Store). Think of it as a “NoBroker” clone tailored for the Indian market, but with extra room for agricultural land and rural-area listings. Core experience I need you to deliver • Property listing: owners, builders and agents should be able to post any type of property—houses, flats, plots, agricultural lands—without brokerage. • Chat between buyers and sellers: an in-app, real-time messenger so users can negotiate privately. • Booking appointments: a simple calendar flow that lets a buyer lock in a site-visit slot and sends push/email reminders. Supported transactions The platform must seamlessly handle buying and selling of...
Project Title: Flutter Sprint: Payment Gateway, Incentive UI, & Penalty Logic (3 Apps) Project Overview We have an existing food delivery ecosystem built with Flutter (Frontend) and Laravel (Backend). We need an experienced Flutter developer to integrate specific modules and fix minor logic issues across three apps: Customer, Restaurant, and Delivery Man. The backend APIs are 100% ready; this is primarily an integration and UI mapping task. Detailed Scope of Work 1. Payment & Marketing SDKs Razorpay Native Integration: Enable UPI Intent flow (direct launch of GPay, PhonePe, Paytm) for Wallet Top-ups. Meta (Facebook) SDK: Integrate App Events for install and purchase tracking. Custom Notifications: Replace default system sounds with provided .mp3 (Android) and .caf (iOS) files. ...
1. Payment Gateway Optimization (Razorpay) Goal: Switch from manual UPI ID entry to UPI Intent (auto-opening apps like GPay/Paytm) or Turbo UPI. Action: Integrate the Razorpay Native SDK (not just a WebView). Scope: Implement this in both the Customer App (for order payments) and Delivery App (for wallet top-ups or security deposits). 2. Call Masking API Debugging Goal: Ensure privacy by masking phone numbers between Customers, Delivery staff, and Restaurants. Action: Audit current API integration across all three apps. Identify why errors occur during the "click-to-call" handshake and fix the state management handling the call triggers. 3. Dynamic Incentive Schemes (UI/UX) Goal: Display real-time earnings potential to drivers based on the new admin panel structures. Action...
I need a cross-platform mobile application delivered for both Android and iOS within roughly four to six weeks. The stack can be either Flutter or React Native, but whichever route you choose must integrate smoothly with a REST-based API layer and rely on Firebase or MySQL on the back end. Core requirements: Email-and-password user authentication Real-time push notifications Clean, intuitive UI/UX that feels truly native on each platform Full deployment support—store listing preparation, signing, and submission Deliverables: Fully functional mobile app Source code in a well-structured repo Build/run instructions Concise technical documentation Evidence of testing (unit and basic UI tests)
I have a complete, well-structured glossary of Indian local-language terms and definitions ready to load into a brand-new mobile dictionary. What I need now is the actual app—clean, fast and intuitive—running on both iOS and Android from a single codebase. Core experience I want the user to have • Instant search that returns relevant matches as the user types • Smooth browsing by thematic categories (I will supply the categories) • A daily “Word of the Day” card, ideally with an optional push notification Community input matters too. Users should be able to suggest new words or edits, but nothing goes live until I approve it in an admin screen or lightweight web dashboard. I will hand you the full content as JSON/CSV along with basic UI refer...

I’m commissioning a fully-functioning mobile application that runs natively on both iOS and Android. You may work in Flutter, or go the native route with Swift for iOS and Kotlin for Android—the choice is yours as long as the final user experience is smooth, secure, and consistent across devices.

Scope of work • Architect the app, build out core screens and flows, wire up any required APIs, and implement testing. • Package and prepare the binaries for TestFlight and Google Play Internal Testing, then guide the final store submissions. • Supply clean, well-documented source code plus a short hand-of...
Flutter Developer Needed – Fitness App with Pose Detection (Motion Comparison Engine) Project Overview We are looking for a Flutter developer to build an APP for a mobile fitness application called CC Fitfor Android and iOS. The app guides users through workout exercises and analyzes body movement during the exercise using the front camera. Pose detection must run locally on the device using: MoveNet Lightning – TensorFlow Lite No video or images should be uploaded to the server.

I already own— or can purchase— the ViserLab “Vinance” script and now need an experienced developer (or small team) to turn it into a production-ready cryptocurrency trading ecosystem that runs smoothly on both web and mobile. Mobile (Flutter) The app must replicate the attached dark-theme screenshots pixel for pixel. Bottom navigation, animations, and every UI detail should line up exactly with those mock-ups; matching the visuals is the top priority. Backend (Laravel) Build or extend a robust admin panel so I can: • oversee user accounts, KYC status, deposits, and withdrawals • adjust individual profit/loss results manually • push platform-wide notices and maintenance messages Core trading modules Please deliver fully working versions o...
I have a complete Figma design for an crypto mobile application and now need it built in Flutter and published under your own Google Play developer account. The core goal is to move from design files to a live, downloadable Android app that meets Google’s current policy requirements. You will take my static screens, wire them up to Flutter code, hook in the back-end endpoints I supply, and walk the build all the way through Play Console review. Because the purpose of this project is strictly crypto, smooth product browsing and purchasing flow must remain central throughout your implementation. Deliverables • Fully functional Flutter project (Dart source, assets, ) matching my approved UI • Release-ready AAB signed with your Play signature, plus a debug build for testing...
I am responsible for administering a mobile application that needs to be transferred from the former developer to a new owner. I need a developer who is proficient in Laravel and able to guide me through the transfer process until the application is up and running again on Google Play and the App Store. This will be followed by updates and corrections to the application.
I’m building a single mobile and web platform where anyone, anywhere, can buy or rent any kind of property—residential or commercial. The app must feel truly global, handling multiple currencies, languages, and location formats while remaining fast and intuitive. To start, I need a complete, production-ready build that includes: • Property listings with powerful filters (price range, location radius, property type, amenities, etc.) • Secure user profiles and authentication, including social sign-in and two-factor options • An interactive map view that supports geolocation, clustering, and quick tap-to-detail navigation The interface has to be clean and modern, with smooth search and onboarding flows. Responsiveness across iOS, Android, and the web is ess...
I am building Eagle Rides, a premium black-car service, and I need a seamless digital experience that matches the luxury we offer on the road. The scope covers a fully-featured mobile app for both iOS and Android as well as a customer-facing website, all sharing a single back-end so ride data, payments and user profiles stay perfectly in sync. Mobile app requirements • Core ride-booking flow: choose pickup/drop-off, select vehicle class, see fare estimate, confirm. • Real-time driver tracking on an in-app map. Accuracy and smooth updates are critical to the customer experience. • Secure payment gateway integration supporting cards and digital wallets, with receipts delivered automatically. Website requirements • Mirror the ride-booking journey from the app s...
I am building an all-in-one marketplace that lets customers book on-demand car washes, schedule laboratory tests, or request in-home nursing care from a single mobile app. The core of the project is a smooth, end-to-end booking experience backed by clear service-provider profiles and transparent user reviews so people can choose the best professional for their needs. Key functionality I must see in the first release: • Robust booking system that supports real-time availability, rescheduling, and cancellations. • Detailed provider profiles showing qualifications, services offered, pricing, and photo galleries. • Ratings & reviews attached to completed jobs to build trust and drive quality. • Secure payment-gateway integration for in-app card payments and futur...
I’m ready to turn a simple idea—a clear, distraction-free task-management utility—into a polished app that lives in both Google Play and the Apple App Store. To make that happen, I need someone who can handle the full journey: coding a stable, modern tool app around core task-tracking features and then guiding it through each store’s review process until it’s publicly available. You’ll be free to choose the most sensible tech stack for a shared code-base (Flutter, React Native or another cross-platform solution are all fine with me) so long as the final result feels native on Android and iOS, meets current store guidelines, and is easy for me to maintain. Key deliverables • Production-ready Android (AAB) and iOS (IPA) builds • All required ...
I have an interactive web prototype for SafeZen—my startup that boosts cognitive performance through quick reaction-time tests and guided focus sessions—and I’m ready to turn it into a polished mobile MVP for both Android and iOS. The feel I’m after is unmistakably minimalist: clean screens, friction-free navigation and zero visual clutter. Core user flow is already validated on the web; your job is to recreate that experience natively (or with a robust cross-platform stack) while keeping the door open for future feature growth. Key functions that must ship: • Reaction-time focus test that runs smoothly on a touchscreen • Pre-recorded guided audio focus session (no user uploads in this phase) • Automatic before/after measurement and focus-scor...
Digital Loan Application Platform (Mobile App + Web Admin Panel) Project Overview: We are building a modern digital lending platform that allows users to apply for personal loans quickly and securely through a mobile application. The platform will simplify the entire borrowing process — from loan discovery and eligibility checking to document submission, approval, and disbursement. The goal is to create a fast, user-friendly, and secure loan marketplace similar to platforms like MoneyView and KreditBee, but with a more modern user experience, automation, and intelligent credit assessment. The system will include a mobile application for users and a web-based admin panel for lenders and administrators to manage applications, approvals, and risk assessment. Key Objectives • Simpli...
I want an online delivery services app in made in one day.
I need a full-featured, small-scale multi-vendor marketplace built natively for both Android and iOS. The app has to let any store—regardless of product type—open a shop front, list items, and receive orders, so the catalog structure must be flexible enough to cover clothing, electronics, home goods, or anything else vendors decide to sell. User roles the system must recognise: - Buyers - Sellers/Vendors - Admin Core flows include simple account creation, product upload with images and variants, cart and checkout, order tracking, and in-app messaging between buyer and vendor. I will also need an admin console (web or app-based) where I can approve vendors, moderate listings, manage commissions, and view analytics. Payment methods to integrate: - Credit/Debit Cards - Bank Tra...
I’m kicking off a brand-new social networking mobile app and want to start with one rock-solid cornerstone: user profiles. Your task is to design and code this core module so we have a clean, extensible foundation for all future features. Here’s what I need from you: • A fully functional profile screen where users can view and edit their photo, bio, and basic details. • Secure account creation and authentication (email, Google, or Apple—whichever you’re most comfortable implementing first). • Simple back-end or cloud setup to store and fetch profile data reliably. • Clear documentation and commented code so any developer joining later can pick up where you leave off. • A short walk-through video or call at hand-off showing how eve...
I’m putting together an all-terrain rover that pairs a Raspberry Pi 5 with an Arduino. The Arduino will sit close to the hardware, polling and driving everything from temperature-humidity probes and distance sensors to an IMU (pitch/yaw/roll, altitude, compass), ESC-PWM motor controllers, speed-over-ground tracking and battery-management read-outs. All of that raw data needs to flow up to the Pi, where it is bundled, logged and pushed over a 4 G link. The Pi also runs the user interface on an onboard touchscreen. I want that interface to launch straight into a clean dashboard with drag-and-drop style widgets so I can rearrange or resize gauges, graphs and buttons while in the field. On the software side I need: • Firmware for the Arduino that publishes every sensor value pl...
I need a cross-platform application—web and mobile—that lets a user pull live flight data from the Skyscanner API, pick the segments they want, and instantly turn those selections into a branded “For Planning Purposes Only” itinerary in PDF format. Scope of work The core workflow is straightforward: a passenger name is entered, live Skyscanner schedules are displayed, the user chooses outbound and return legs, and a clean, clearly labeled itinerary is produced. The PDF must list airline, flight number, route, dates, times, booking class where available, plus a conspicuous disclaimer confirming it is not a boarding pass or ticket. No ticket-like barcodes or IATA boarding layouts are to be shown. Key technical notes • Front-end: any modern framework is welcome ...
I am starting from a beginner level and need to master no-code development in FlutterFlow, tie it seamlessly into Firebase, and round everything off with reliable UPI payment integration. Because my company’s project details are confidential, every explanation must be carried out with dummy data or in a generic sample app; I will then replicate the same steps inside our private repository. Live, one-on-one sessions over a screen-sharing platform are essential. I learn best by working through real examples while asking questions in the moment, so each meeting should be highly interactive and task-driven. We will begin with Flutter UI design fundamentals inside FlutterFlow, then progress through backend setup, Firebase authentication, Firestore/Realtime Database, cloud functions, and ...
I’m building the first version of a mobile app both iOS and Andriod entirely in FlutterFlow, backed by Firebase, and I’d like an expert who can set up a solid, no-code foundation that we can keep expanding. Current scope • User onboarding with Firebase phone-number authentication only (no email or social logins for now). • In-app purchase flow powered by UPI. The app must support both subscription plans and one-time premium unlocks, all handled inside FlutterFlow and recorded in Cloud Firestore/Realtime DB for entitlement checks. • Clean data architecture in Firebase so future modules can be added without painful refactors. Deliverables 1. A ready-to-publish FlutterFlow project with UPI payment widgets and verified test purchases for subscriptions an...
I have an existing Flutter application running on both Android and iOS with Laravel backend that now needs a complete quality sweep. The first priority is to put every screen and flow under a microscope—especially the Login/Register process, the full payment pathway, and user-profile management—so I know exactly where things break, lag, or confuse users. Once a clear, reproducible bug list is in hand, the same engagement rolls straight into fixing those flaws in the codebase. While doing so, please keep an eye on navigation flow and overall user interaction; if small tweaks there can make the app feel smoother, include them in your pull requests. Visual design changes aren’t required this round, but I welcome concise suggestions if you spot quick wins. Deliverables &b...
I need a full-featured mobile application that mirrors everything fans currently enjoy on the website, but delivered natively on both iOS and Android. The heart of the build is real-time cricket coverage: lightning-fast live scores, ball-by-ball commentary, and dynamic match schedules that update automatically. Beyond the core scoreboard, I also want team and player statistics displayed in an easy, swipe-friendly format. To keep users coming back, the app must pull in the latest cricket news and let them dive into social-media-style discussions around each match. Push notifications are essential so followers never miss a wicket, milestone, or breaking headline. If you have experience with sports data APIs, real-time socket updates, and smooth cross-platform UI/UX (React Native, Fl...
I’m ready to turn an idea inspired by the Gottman CardDecks APP to a similar app but in Italian. This is the app I want to inspire to: --> only some Menus of this app, not all of them. ## Numbered list of requirements 1. **App concept and overall structure** The app should be a mobile app for couples, inspired by the general structure and user experience of the Gottman app, but limited to a specific set of features only. The full app content and interface must be in **Italian**. The design should feel warm, clear, intuitive, and clinically appropriate. 2. **Platforms and technical delivery** The app must be fully functional on both **iOS and Android**. A cross-platform solution such as **Flutter** or **React Native** is welcome, though native development is also accep...
I want a lightweight mobile app that convincingly imitates the HDFC Bank interface so I can prank a friend with an impressive “account.” The app will live only on my phone; it never needs to hit an app store or connect to any real banking systems. Core screens (2-3 in total) • Account balance page showing a customisable figure • Transaction history screen with editable, fake entries • Money-transfer form that appears functional but does nothing once “sent” Look & feel Please mirror the current HDFC Bank mobile design as closely as possible—colours, typography, and general layout. Accuracy matters because the joke depends on immediate visual credibility. Behaviour & data Everything can run fully offline. A simple local JSON o...
I need a fully functional real-time stock-trading application that runs on both iOS and Android. The focus is speed and reliability: users should see market movements the instant they happen and be able to act just as fast. What must be in the first release: • Live stock prices and interactive charts streamed with sub-second latency • Instant buy/sell order execution wired to a reputable brokerage API • Secure user account management for sign-up, KYC, portfolio view, and transaction history You’ll design the UI, build the mobile front-end, integrate real-time data feeds, and set up any supporting back-end needed for authentication, push notifications, and data caching. Clean, well-documented code in a Git repo is required for hand-off to my in-house team. Ex...
I want a straightforward tool that lets users type an Indian vehicle registration number and instantly see its official details. The solution must come in two flavours—a responsive website and a companion Android app—sharing the same backend and database so results stay consistent everywhere. A single search box on the landing screen is enough; once a number is submitted the results page should display the owner’s name, number ,make / model, vehicle class, fuel type, registration date, RTO location, insurance provider with expiry, and anything else the Parivahan (or another reliable Indian RTO) API returns. Please wire the system directly to the Parivahan API or an equally accurate Indian RTO vehicle database. If rate-limits or special authentication apply, include those...
I want to turn the Red Fort’s rich past into an engaging, self-guided mobile experience. The core of the project is a historical tour guide presented as a smartphone app. Scope • Research and distill the fort’s key stories—from its construction under Shah Jahan and two-century reign as the Mughal seat, through the 1857 uprising and the capture of Bahadur Shah Zafar—into a logical walking route inside today’s complex. • Build the app for iOS and Android, displaying each stop with photos, concise text, and, most importantly, high-quality audio narration (my selected must-have feature). • Integrate basic offline functionality so visitors can explore without reliable data coverage. Audio I need a warm, informative voice track for every...
I’m putting together a multi-phase product that spans a Laravel web back-end and a Flutter mobile front-end, and I want one reliable developer who can stay with the project well beyond the initial release. You’ll move fluidly between the two stacks: building and refactoring Laravel APIs, crafting efficient database queries, and then switching over to Flutter to translate that data into intuitive, responsive screens. Code quality and clear, frequent communication matter to me more than racing through tickets; I’d rather see well-structured controllers and neatly organised Dart widgets than quick fixes that need revisiting. If you know how to version-control properly with Git, write concise documentation as you go, and test your own work before handing it off, we’l...
I need an end-to-end order processing and delivery solution that runs smoothly on the web, Android, and iOS. The entire system will be used exclusively by admins and managers, so the interface must surface the information they need without clutter. Core workflow • Orders are created or imported into the system, then move through clear fulfilment stages. • Real-time order tracking shows current status, location data, and time stamps. • A user-management module lets me add, deactivate, or edit staff profiles and set role-based permissions. • A built-in analytics area should visualise daily volumes, delivery times, and performance trends that can be filtered by date range, team, or individual driver. Tech expectations A single, secure API should power all three...
I’m building a cross-industry service platform that lets customers instantly book qualified engineers for IT support, general maintenance and MEP works. The scope covers two user roles only—customers and service engineers—each with its own mobile interface, while a shared backend keeps everything in sync. Core flow • Users sign up and log in exclusively with a phone number OTP flow. • Customers search or filter service categories, enter job details, confirm the request and see the engineer’s live approach on Google Maps once the task is accepted. • Engineers receive real-time job notifications, review details, head to the site and update status points (on the way, arrived, completed), again reflected through live map tracking and whats-up integ...

I need a fully-functional mobile marketplace built for both iOS and Android and released within the next month. The app must support two clear roles—Buyers and Sellers—each with its own sign-up, authentication, and dashboard experience. Once inside, Sellers should be able to create rich product listings with photos, pricing, and descriptions, while Buyers browse or search those listings quickly and intuitively. A secure, in-app checkout is essential, so please plan to wire in a mainstream payment gateway (Stripe, PayPal or a comparable solution) and handle the usual edge cases: saved cards, failed transactions, refunds, and basic reporting. Because time is tight, choose a cross-platform stack you are comfortable delivering fast—React Native, Flutter, or another framewo...
I need a full-featured, cross-platform mobile application that will serve as a streamlined e-commerce storefront on both iOS and Android from a single codebase.

Key deliverables • Product catalog that supports categories, search, and rich media • Seamless payment gateway integration (Stripe or similar, with PCI-compliant flows) • In-app user reviews and ratings tied to individual products I’m open to frameworks such as Flutter or React Native if they help accelerate delivery while keeping native-like performance; feel free to suggest the stack you’re most comfortable with. Clean, maintainable code, basic unit tests, ...
I need a full-featured mobile application that helps college students learn faster and stay organised. The core idea is an educational hub where users can watch short concept videos, take auto-graded quizzes, and track their progress on personalised dashboards. I am open to native iOS/Android or a cross-platform framework such as Flutter or React Native—whichever you feel will give us smooth performance and a modern look within a reasonable build time. Key deliverables • Clickable UI/UX prototype for approval before coding • Fully functional mobile app with video streaming, quiz engine, progress analytics, and push notifications • Clean, well-commented source code stored in my GitHub repo • Basic admin panel or API endpoints so I can upload new lessons...

I’m launching an online imitation-jewellery brand and need a complete digital storefront that works flawlessly both as a mobile app and as a browser-based site. Core shopping functions must be in place—customers should be able to add items to a cart, save favourites to a wishlist, and leave detailed reviews after purchase. Because many buyers look for styling guidance, I also want a built-in “personal requirement” feature: visitors can describe an outfit, occasion or preference and instantly receive product suggestions (either through a simple questionnaire or live chat prompt—whichever you recommend for speed and ease). The design should reflect the elegance and sparkle of costume jewellery while remaining lightweight and responsive. A secure checkout f...

I’m ready to move from concept to code on a brand-new productivity app and need a developer who can deliver a polished experience on both iOS and Android from day one. At its core, the app must let users create and track tasks, view and sync those tasks with their calendar, and collaborate seamlessly with teammates in real time. The flow should feel effortless: • quick task capture with priorities and due dates, • automatic calendar updates so schedules stay in sync, • shared workspaces where team members can comment, attach files, and see progress instantly.
