...built-in address form with basic distance checks; I already work with local couriers, so no third-party integration is needed right now User accounts are optional. Guests must be able to order without any sign-up friction, but if someone wants to register (email, Google, or Apple), the app should remember their past orders and delivery details. I’m open to the tech stack—Flutter, React Native, Kotlin/Swift, or another modern approach—as long as the result runs smoothly on both iOS and Android and I receive full, well-commented source code. Deliverables - Cross-platform mobile app published to TestFlight / Google Play testing tracks - Lightweight admin panel or JSON-based CMS for instant menu updates - Branded splash screen and color scheme that matche...

I’m looking to get a lean, no-frills P2P bidding app built for Android along with a small web-based admin panel. The goal is to let users register, place bids on each other’s listings, and chat inside the app. A basic payment gateway is needed, but only for optional premium features or subscriptions—regular bidding itself stays free. Key things I need covered • Android app (Kotlin or Java, whichever keeps development light) • Secure user registration / login • Simple bid-placing workflow with status updates • In-app messaging between the bidder and the listing owner • Payment integration limited to premium tiers (UPI or Razorpay would be ideal) • Admin panel where I can view users, approve listings, and track premium purch...

I will give you repo access and...

...replacement, filterable by supplier or date. For each entry the app must capture: • Item ID and description • Condition and defect details • Date of replacement and customer information • Status of pending replacements, grouped by our customer when possible No push, real-time, or scheduled notifications are needed; users will open the app for status checks. Technical notes You may build in Kotlin or Java and store data locally with Room or SQLite—whatever keeps the code clean and maintainable. A simple, intuitive UI is more important than sophisticated visuals. Deliverables • Complete Android Studio project with readable source code • Build instructions plus an installable APK or AAB If you have questions or see a smarter...

Typical tasks include: • Squashing bugs as they’re reported • Applying small UI or UX adjustments • Updating SDKs, libraries, or certificates to stay store-compliant • Adding minor features or configuration changes when required You should already be comfortable shipping to both App Store and Google Play and have experience with at least one mainstream stack—native Swift/Kotlin or a cross-platform option like React Native or Flutter. Clear Git practices and responsive communication are important because I’d like quick turnarounds on incremental tickets. If you enjoy occational, bite-sized work that keeps an app i...

I need a short-term partner to build a small, native Android productivity app. The scope is intentionally light: just the essential screens and logic that prove the concept works end-to-end. Here’s what I expect: • Clean Android Studio project written in Kotlin or Java, targeting the latest stable SDK. • Simple UI that demonstrates the core productivity workflow (e.g., adding, viewing, and persisting basic items locally). • Local data storage using Room, SharedPreferences, or another lightweight option—whatever you feel is fastest to implement and easy to extend later. • An APK plus source code that compiles without errors and runs on common Android 10+ devices. I’m not looking for fancy graphics, user-accounts, or cloud sync right now—j...

I need a lightweight Android app built with Kotlin in Android Studio that acts as a TCP client. Its sole purpose is to let me enter a server’s IP/port, send plain-text messages, and immediately show the echoed or returned text in the same screen. A scrolling conversation view, a simple input box, and a “Send” button are all the interface components I’m after—no fancy styling required, just something easy to read during debugging sessions. The app must open and manage the TCP socket on a background thread, keep the UI responsive, and cleanly close the connection when I leave the activity. Incoming data should appear in real time in the display area; I don’t want it hidden away in logs. Logging to Logcat is fine in addition to the on-screen feed, b...

I need a straightforward productivity app built for Android only. For this initial phase I’m keeping the scope intentionally lean—just a clean, functional proof-of-concept that can run on curren...versions.

A simple rewards or favorites feature so users can save ads for later. Potentially a little interactivity, like a quick poll or occasional tip to add extra value. Technical Requirements: Native Android development (Kotlin or Java). Clean, minimal widget design with full documentation. Code should be structured for easy future updates. Budget: For this initial MVP, I’m looking at a modest budget, with the understanding that we’ll have a follow-up phase for more advanced features. Write 10 10 in letter format so i know you read the project and put my name backwards behind the ...

...When offline, users should still be able to browse cached data, create or edit records, and receive visual cues that their updates are pending. • Sync logic has to manage conflicts gracefully and keep the local store lightweight. • Push notifications need to relay reminders and status updates exactly as the browser version does. I’m open to React Native, Flutter, or fully native Swift + Kotlin as long as the final builds pass App Store and Play Store review without issues and the codebase is easy for my in-house team to maintain. Deliverables 1. Source code with clear modular structure and inline documentation. 2. Test-flight/alpha builds for review on both platforms. 3.

Technical notes – Android first (React Native, Flutter, or Kotlin—whichever you work fastest in). – Clean, modern UI; no need for elaborate branding, just intuitive navigation and clear icons. – Code should be modular so future features—real-time tracking, secure payments, service-provider chat—can bolt on later. Deliverables 1. Installable APK and source code. 2. Brief setup document and o...

...driver-and-passenger rating flow that appears once each trip ends. That’s the full feature set for now. If a lightweight admin panel is absolutely necessary to support these functions, let me know the simplest, most budget-friendly approach; otherwise, we can defer it to a later phase. Use any modern, cross-platform stack you can maintain confidently—Flutter, React Native, or a native pair (Kotlin + Swift) are all fine. Hand-over items I need: • Clean, well-commented source code in a version-controlled repo • Setup instructions that let me build and run the app locally • A short video or screenshots proving the three core features work end-to-end Propose a realistic timeline and milestones. If you’ve built similar mobility or on-dem...

I’m looking to turn my astrology concept into a working Android app. The very first milestone is a solid, well-structured codebase with user authentication built in. Scope • Build a native Android application (Kotlin or Java). • Implement mandatory account creation and sign-in—email/password or a secure provider such as Firebase Auth. • Set up a clean screen flow that I can extend for horoscope, natal chart, and compatibility modules later. Placeholders or simple demo data are fine for now; the emphasis is on architecture. What I need from you 1. A functional prototype APK and complete source code. 2. Modular design that lets me plug in additional astrology features without rewrites. 3. Clear, inline code comments and brief setup documentation. ...

I’m ready to turn a new idea into a fully functioning Android app and need a developer who can guide the entire journey—from refining the concept through design, coding, testing, and a successful Play Store launch.

Keep the architecture straightforward—Kotlin with MVVM + Jetpack components is perfect, but I’m open to a comparable modern stack. Please organise the code so future screens can plug in easily. Deliverables 1. Full Android Studio project, compile-ready. 2. One APK build suitable for internal Play testing. 3. Brief read-me covering project setup, Firebase configuration steps, and ...

...I need NEW junior Level developers of Android using JAVA. I’m putting together a small, ongoing project and need a junior-level Android developer who wants consistent, long-term work. The codebase is already live on the Play Store, but it needs steady attention: light refactors, incremental feature additions, and the occasional bug fix or UI polish. You’ll be working in Android Studio with Kotlin (a bit of Java still lingers), pushing updates to Git, and communicating through Slack and simple pull-request reviews. I write the product specs and provide UI mock-ups; your job is to turn those into clean, testable code and follow through to a successful Play Store release. Typical weekly flow • Review the upcoming ticket list I’ll share each Monday ...

I need to bring my cab-hailing app up to date on both iOS and Android. Every third-party library, native framework, and in-house feature has to be migrated to the latest stable versions so the builds compile cleanly in Xcode 15 / iOS 17 and Android Studio Giraffe / Android 14, without breaking any existing functionality. Your work will start with a dependency audit: identify outdated Swift, Kotlin/Java, and cross-platform libraries, note deprecations, and map out the required migration steps. After the libraries and core frameworks are upgraded, you’ll modernise the app-side features that rely on them—push notifications (APNs + FCM), real-time driver tracking with maps, in-app payments, and the background location service. Because the app is live, stability is critical...

I have a kiosk-style mobile app fully written in Flutter (Dart) and I need it rebuilt natively in Kotlin for Android.
