Android Developer Needed — AI Email Writer App Project Overview I am looking for an experienced Android developer to build a complete, polished AI-powered Email Writer application. The app should allow users to generate professional emails using AI by entering a purpose/context and selecting options such as email type, tone, length, and language. IMPORTANT — REFERENCE APP The new app should look and feel as close as possible to the reference application, including its overall UI, UX, layouts, navigation, colors, components, screens, and user flow. Reference app: [login to view URL] Please review this reference before submitting your proposal. I want the finished application to closely reproduce the reference app's: Overall visual style Screen layouts Navigation Color palette Typography Buttons and input fields Cards and selectors Icons and spacing Email generation interface Email editing interface History Favorites Search Settings Dark mode Loading and empty states Overall user experience The reference should be treated as the primary UI/UX specification. The developer must build the app independently with a new codebase. Do not copy proprietary source code, logos, copyrighted graphics, or unauthorized assets. Use my own branding and properly licensed/original assets while maintaining the same overall design direction. Core Features AI Email Generation Integrate an AI/LLM API such as Groq or another suitable provider. Users should be able to: Enter recipient information. Describe the purpose/context of the email. Select email type. Select tone. Select email length. Select language. Generate the email. Edit the generated subject and body. Copy, share, save, or favorite the email. Tones Include at least: Professional Friendly Formal Casual Persuasive Empathetic Assertive Diplomatic Enthusiastic Concise Email Types Include at least: Business Job Application Sales Customer Support Follow-Up Thank You Apology Invitation Academic Cold Outreach Complaint Request Meeting Networking Recommendation Resignation Cover Letter Reminder Congratulations Introduction The architecture should make it easy to add more types later. Length Short Medium Long Languages At minimum: English Spanish French German Italian Portuguese Arabic Chinese Japanese The AI should respect the selected language, tone, type, and length. Email Editing Users must be able to edit: Recipient Subject Email body Generated content must not be locked. Users should be able to modify an email before saving, copying, or sharing it. Email History Implement a local email history system. Users should be able to: View generated emails Open emails Edit saved emails Delete emails Favorite/unfavorite emails Copy emails Share emails History should be stored locally on the device. No mandatory account should be required for basic history functionality. Search & Sorting Search email history by: Recipient Subject Purpose Content Sorting options: Newest first Oldest first Favorites UI/UX The UI is extremely important. The app should closely follow the reference application's overall design and experience while using original implementation/assets. Requirements: Modern Material Design 3 Clean navigation Attractive buttons and input fields Cards and selectors Consistent typography Proper spacing Appropriate icons Smooth transitions where appropriate Loading states Error states Empty states Light mode Automatic dark mode Portrait support Landscape support Responsive layouts The result should look like a professional commercial application, not a basic prototype. Settings Include a Settings screen with options such as: AI API configuration Default language Default tone Default email length Theme About Privacy information API credentials must not be hard-coded into the source code. If the user enters an API key locally, it should be stored using appropriate Android secure storage. Privacy & Security The app should follow a local-first approach for email history. Requirements: No unnecessary user data collection No mandatory account for local history Secure API-key storage No hard-coded private API keys Proper handling of API errors Clear documentation of what data is sent to the AI provider Please explain your API-key security approach in your proposal. Technical Requirements Preferred: Native Android Kotlin Jetpack Compose Material Design 3 Room or equivalent local database Modern Android architecture REST/API integration Secure local storage Clean, maintainable code The project must be professionally structured so another developer can maintain and extend it. Monetization-Ready The architecture should allow future integration of: Google AdMob Monthly/yearly subscriptions In-app purchases Premium features Usage limits Free/premium plans AdMob and subscriptions can be added separately if not included in the initial scope, but the project should be designed to support them later without a major rewrite.

Reproducing the reference app's look while writing a clean, original Kotlin codebase is the real challenge here — the UI must feel commercial, and the AI layer must respect tone, type, length and language reliably. I've shipped 80+ apps since 2008, many native Android (Kotlin), plus subscription billing systems, so the monetization-ready architecture won't need a rewrite later. Approach: (1) build the Compose/Material 3 design system — cards, selectors, states, dark mode, landscape — matching the reference layout with your branding; (2) implement a repository layer over Room for history/favorites/search/sorting and a provider-agnostic LLM client with structured prompts per tone/type/language; (3) store the user's API key in EncryptedSharedPreferences backed by Android Keystore, never in source or Gradle, with full error handling for invalid keys. Which AI provider do you prefer — Groq or another?

AI EMAIL APP Howdy, An AI email writer is only useful if generating a polished email feels faster and simpler than writing one from scratch. I’d focus on reproducing the reference app’s experience closely while building a clean Android foundation that can support more AI features and monetization later. I can build this as a new native Android project using Kotlin, Jetpack Compose, Material 3, and Room, with a maintainable architecture for expanding email types, tones, languages, and future features. For AI generation, I’d evaluate Groq or another suitable LLM API based on quality, cost, latency, and multilingual support. API credentials would never be hard coded, and user provided keys can be stored securely on the device with clear documentation around data sent to the AI provider. The scope would include the complete UI, generation and editing flow, local history, favorites, search, sorting, settings, dark mode, responsive layouts, testing, APK, documentation, and complete source code handover. I can show you relevant Android and AI app examples in chat. Portfolio link: https://www.freelancer.pk/u/Hammadhassan21 Best regards, Hammad Hassan

Yes — I can handle this end to end. For a AI-Powered Email Writer Android Application, the key is not just the screens but keeping the API and platform-specific behavior stable across devices. The strongest positioning is showing we understand the delivery risk hiding behind the brief, not just the feature list. Key scope I would cover: Input workflow design, prompt/control rules, and output validation; Backend processing, file/document generation, and dashboard usability. If helpful, I can map the input-to-output workflow and where validation should sit before implementation. Quick question: What part of this build has caused the most delivery risk so far: architecture, integrations, or product clarity? Also, if we align on the core scope first, would you prefer the first milestone to focus on a stable MVP foundation or on feature breadth? Best, Dr. Syafiq

AI EMAIL APP Hi! This is something we can build without issues. I have reviewed the reference AI Email Writer application and can reproduce its UI/UX, screen structure, functionality, and overall visual style in a newly developed Android application. Before I put a firm number together, one thing genuinely changes the architecture: are users expected to enter their own API key in the Settings screen, or do you plan to proxy the AI calls through a backend under your account? The first keeps things simple — the user covers their own API costs and there's no server to maintain. The second gives you real control over usage limits and free/premium tiers, but it means building and hosting a thin middleware layer. Both are solid paths; which one you want shapes the security model and how the monetization hooks actually work. On how we'd build it: Kotlin with Jetpack Compose and Material Design 3 is the natural fit — theming, dark mode, and the component library all come standard rather than retrofitted. Room handles local history and favorites with no server dependency, which keeps the privacy story honest. API keys would live in EncryptedSharedPreferences, never in the source. The architecture would follow MVVM with a clean use-case layer, so dropping in AdMob or Play Billing later is a module addition, not a rewrite. Groq is a reasonable default for the AI provider given latency and cost, though we can swap that out based on your preference. Gustavo & the DoTheCode team

Hi, Mateo here, from Toronto. Building an app "as close as possible" to a reference while genuinely owning original code and assets is exactly the discipline here, I'd treat the reference purely as a UX blueprint, layout rhythm, navigation flow, component hierarchy, and rebuild every screen with my own implementation and your branding, so nothing traces back to their proprietary source or graphics. For API-key security, I'd store it using Android's EncryptedSharedPreferences (backed by the Keystore), never hard-coded, entered locally by the user and never transmitted anywhere except directly to your chosen AI provider. I'd recommend Groq for the LLM layer given its speed and cost profile for short-form generation tasks like emails, with the API integration abstracted behind an interface so switching providers later doesn't touch the rest of the app. I'd build this natively in Kotlin with Jetpack Compose and Material Design 3, Room for local history storage, and structure the architecture so AdMob and subscriptions slot in later without a rewrite, exactly as you specified. Looking forward to working with you.

Hi, I’ve built Android apps with Kotlin and Jetpack Compose, integrating AI calls and local storage. You’re aiming for a polished UI that mirrors the reference while staying maintainable and easy to extend. I’ve delivered AI-assisted content apps and secure local storage patterns in production. I’d start by validating the current flow, then implement AI generation with tone/type/length controls and a local DB for history. I’ll wire up secure API key handling and incremental UI parity with the reference, with thorough in-app validation. One risk is securely handling API keys and gracefully recovering from AI API errors. What should happen if a generated email loses formatting when the language changes after generation? Should the local history support export/import or cloud sync in future updates? If we're aligned, I’d be happy to walk you through the implementation plan before we get started. Best regards, Brandon

Hello⭐️, This app is primarily an AI workflow combined with a local-first email management system, so the important part is keeping generation, editing, history and favorites consistent rather than treating each screen as an isolated feature. I’d build the Android app with Material 3 around reusable selectors and email components, connect the generation layer to the chosen LLM API with structured prompts for type, tone, length and language, and keep history, search, sorting and favorites stored locally without requiring an account. The reference app can guide the visual hierarchy and user flow while the implementation, branding and assets remain original. I’d also handle loading/error states, editable generated content, sharing/copying, dark mode and API failure handling, then test the complete generation-to-save workflow across different languages and configurations. If the reference source already defines any API or data-model assumptions, sharing those details would help determine what should be reproduced functionally versus redesigned. Have a nice day

Hi, The AI Email Writer app aims to deliver a seamless, professional email generation experience closely matching a reference UI while supporting multiple languages, tones, and email types. The main technical risk is ensuring reliable, low-latency orchestration between user inputs, AI generation, and local data persistence, especially under variable network conditions. I led the DocIntel AI project, which involved designing a scalable AI-driven platform integrating LLM APIs with local and cloud data stores, focusing on robust orchestration and user-facing reliability. This experience aligns with the core challenges of your app's AI integration and local history management. I typically design systems by separating the AI orchestration layer from local storage and UI layers to isolate failure points and simplify testing. Early validation of API error handling and secure local storage of sensitive API keys will be critical architectural decisions. To ensure production readiness, I recommend implementing fallback routing and clear error states for API failures, plus secure storage mechanisms compliant with Android best practices to protect user API keys and data. I can start by outlining the AI orchestration flow and local database schema to confirm requirements and dependencies. Thanks, Clifton
