From 38,430 reviews, clients rate our PhoneGap Experts 4.9 out of 5 stars.I am moving “Naufumi” from prototype to production and need the entire stack rebuilt from scratch in Flutter with Firebase on the back end. The goal is a clean, scalable codebase that can support Android, iOS, a responsive web app, and a browser-based super-admin panel within 30 days. Scope and requirements • UI: I’m fine with moderate customization—clean, modern layouts built on proven component libraries are preferred over pixel-perfect bespoke screens. • Authentication: phone-number login secured with a standard OTP flow. • Core marketplace: the Stores section (browsing, cart, checkout, order tracking) comes first in priority, followed by Jobs, Services and Rentals, so architect the data models with that hierarchy in mind. • Maps: int...
Project Description: We are looking for an experienced Unity Developer (Unity 6) with proven expertise in Arabic localization (RTL support) to adapt our existing mobile app from standard English (LTR) to Arabic (RTL) for publishing in markets such as the UAE and Saudi Arabia. The primary scope involves converting all in-app text and UI elements from Left-to-Right (LTR) to Right-to-Left (RTL) format in a meaningful and culturally appropriate manner. This includes proper alignment, layout adjustments, font handling, and ensuring overall UI/UX consistency in Arabic. Key Responsibilities: Implement full Arabic language localization within Unity. Convert UI layouts from LTR to RTL properly (including buttons, menus, navigation flows, and text alignment). Ensure correct Arabic text rendering ...
I want to launch a mobile experience that blends live-stream shopping with seamless, in-app purchasing—think TTS. The build must ship for both iOS and Android from day one, with user accounts that can authenticate either through email/password or the major social platforms. Core functions I need working flawlessly: • Real-time live streaming where hosts can pin products on screen • A browsable product catalog that stays synced with my backend • One-tap, secure checkout inside the stream and in the catalog view Because I do not have a fixed preference on framework, you’re free to recommend React Native, Flutter, or any stack that delivers smooth video, stable commerce flows, and maintainable code. When you reply, please include: • Direct links or s...
I want a simple, reliable way for families to see exactly where their school bus is and how long it will take to reach their stop. The core flow is straightforward: • Students or parents open the app on iOS or Android, choose their school, bus number and stop from three drop-downs, and immediately see the bus’s live position on a Google Maps view along with an ETA to their selected stop. • The driver runs a companion screen on the same app; when they tap “Start Trip” the phone begins broadcasting its GPS location. Once the route is finished, they tap “End Trip” and tracking stops. • Only two roles are needed for the first release—Students/Parents (view-only) and Drivers (share location). A future administrator role could be added late...
I’m expanding our mobile team and want an experienced developer who is equally comfortable in Flutter (Dart) and React Native (JavaScript/TypeScript). Our live products run on both iOS and Android, so every feature you tackle must compile cleanly and perform smoothly on each platform from the first build.

The goal is to build a lightweight Android utility focused on task management. Core capability centres on notifications and reminders—covering everyday to-dos as well as specialised payment nudges and simple order-processing follow-ups—delivered reliably on Android 8.0+ devices. Scope of work • Create the full Android application in Kotlin (Java is acceptable if strongly preferred) with Android Studio. • Design clean Material-compliant screens for adding, editing and browsing tasks. • Persist data locally with Room; structure the code so a future cloud sync (e.g. Firebase) can slot in without major refactoring. • Implement a reminder engine that schedules push notifications, survives device reboots and handles recurring events such as monthly paymen...
I’m building a fully native mobile application that lets drivers book automotive services The core flow is simple: users create an account (email, phone, or social login),check real-time availability, reserve a time, then pay securely without ever leaving the app. Both iOS and Android need to feel identical in look and speed, so I’m expecting Swift/SwiftUI on the Apple side and Kotlin with Jetpack on Android, backed by a single REST or GraphQL API.

I’m ready to turn my outline for a combined journal, diary, and planner into a polished product that users can open on iOS, Android, and any modern browser. The core experience must feel unified, so daily journaling, task planning, and goal-tracking must live side-by-side in one clean interface. My users expect to start writing offline on a phone, continue on the web, and see the same content instantly on a tablet. To make that seamless, the build has to include: • Sync across devices in near-real time • Reliable cloud backup with simple restore • Full offline mode that queues changes until a connection returns A single codebase such as Flutter, React Native, or another robust cross-platform framework is preferred, as long as you can guarantee smooth perform...
I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: ...

I am starting my second round of beta testing within the next 2 weeks.

Developer Deliverables: 1) Create a Capacitor wrapper project 2) Configure it to load: 3) Ensure Stripe links open in Safari/...
I’m turning a concept into a working mobile application that runs natively on both iOS and Android. The very first milestone is to set up a clean, maintainable codebase and wire in secure email-and-password authentication. I’m flexible on the tech stack—whether you prefer Flutter, React Native, Kotlin Multiplatform, or another cross-platform framework—so long as the result feels native, performs smoothly, and can be extended easily. Deliverables • Single codebase compiling for iOS and Android • Onboarding flow: sign-up, sign-in, password reset, session persistence • Placeholder home/dashboard screen ready for future features • Well-commented code pushed to my private Git repo with clear build/run instructions I’ll consider the ...
I want to launch a cohesive suite of AI-powered creation tools that runs smoothly in any modern browser and ships as a companion iOS/Android app. The platform will revolve around four core experiences: • Chatbot: A conversational assistant driven by a large language model (OpenAI GPT-4, Claude, or a comparable open-source model) with memory, retrieval-augmented generation, and an admin panel so I can refine prompts and monitor usage. • Image & Video Generator: Text-to-image and text-to-video pipelines using Stable Diffusion / Stable Video Diffusion (or a stronger alternative) with prompt weighting, negative prompts, and upscaling. • 3D Image Generator: Generation of glTF/OBJ assets ready for WebGL display, including basic texture baking. • AI-Assisted Video E...

I have built an app using lovable and want it now turned into an app on ios and android. It doesn't need to go in the app store, it can be published via test flight for iOS packaged as an apk for android as it only needs to be used by about 100 users. Ideally we will be able to update code in github and the apps will update on the devices, but i understand if this is not possible. App will need permissions for GPS, using the camera, saving photos to the local library and push notifications. Frontend: React 18 + TypeScript, built with Vite, styled with Tailwind CSS and shadcn/ui (Radix UI components) Backend: Supabase (hosted PostgreSQL database, authentication, file storage, and Edge Functions written in Deno/TypeScript) Routing: React Router v6 (single-page app) State Manage...

I’m putting together a lean, first-release ride-share/taxi app whose sole focus is fast ride booking and driver–rider matching. For this initial build we only need single-ride trips—no carpooling or luxury tiers yet—so the flow stays simple: choose pickup and destination, see the fare, and get paired with the nearest available driver. Two extra touches are essential: riders must be able to schedule a trip in advance and cancel it from inside the app if plans change. Everything else (pricing rules, surge logic, etc.) can live in an admin web panel you create alongside the apps. I’m happy with either native iOS/Android or a cross-platform stack such as Flutter or React Native; Google Maps (or Apple Maps on iOS) should power the driver’s navigation. The p...
