The concept, user flows, and core screens are already sketched; now I need a developer who can turn them into a polished, production-ready app. Here’s the outline of what I’m after: • Full Android build in Kotlin (Java is acceptable if you have strong reasons). • Standard social features—secure sign-up/login, user profiles with photos, a simple post feed, likes/comments, and real-time chat or messaging. • Cloud-based back-end: I’m leaning toward Firebase for authentication, Firestore/Realtime Database, and push notifications, but I’m open to alternatives if you can justify them. • Clean architecture, modular code, and clear naming so another dev can jump in later if nee...
I own a licensed copy of the Dooo Movie Streaming Android source code and now need it running live on Google Play. The current project refuses to compile because of dependency issues and an outdated SDK. Here’s what I need from you: • Open the project in Android Studio, upgrade it to the latest stable SDK/Gradle versions, and cleanly resolve every dependency conflict so the APK builds without warnings. • Configure package name, signing key, Firebase/Ad-mob (if present in the code), and any other runtime settings the template requires. • Run a full device/emulator test to confirm login, streaming, search, and push-notification flows all work exactly as in the template demo. • Generate release AAB/APK and guide me through—or directly handle—th...

I’m building a small bionic butterfly that “flips” in mid-air, powered by an ESP32-S3 Super Mini. What I still need is the full control system: firmware for the board plus a cross-platform mobile app that drives two micro-servos through a joystick interface. Here’s the flow I’m picturing: • The ESP32-S3 runs custom firmware (Arduino IDE or ESP-IDF—whichever you prefer) advertising itself over BLE. • The mobile app—working on both Android and iOS—connects, shows a virtual joystick, and streams position data in real time. • The board translates that data into precise PWM signals so each servo can beat the wings smoothly and synchronously. I will supply the hardware (ESP32-S3 Super Mini and servos) for your testing if nee...

I need a very small Android application whose only job is to launch and immediately play a single MP4 video in full-screen. As soon as the user taps the app icon, the video should start on its own—no play, pause, seek bar, or any other controls visible. After the video finishes, the app can simply close or loop; I’m open to whichever is quickest to implement. The MP4 file will be provided. Please package it inside the APK, so the app works offline with no additional downloads. Android Studio, Kotlin or Java, and the built-in VideoView or ExoPlayer are all fine as long as start-to-finish playback is seamless on Android 8.0 and above. Deliverables: • Signed release APK for testing • Complete source code project that compiles in the latest stable Android Studio &bu...

I’m running an ongoing fraud-prevention test for RingApp and need help from people who are physically in Palestine, using an OOREDOO SIM on an Android phone. After installing the app, all you have to do is sign up with your OOREDOO number, open the profile screen, enable “Auto-perform tasks,” and leave the app active in the background. RingApp will trigger and instantly decline test calls on its own; you won’t have to answer or dial anything manually. Each block of 200 completed test calls releases a $5 milestone through Freelancer. The app tracks the call count for you, so payment is straightforward once the counter reaches 200 and the data syncs. Acceptance criteria • RingApp is installed and registered on an Android device with an OOREDOO SIM. • &...
I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a file—primarily images or PDFs—from local storage and send it securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response. If you prefer Java that’s fine—as long as the final APK/AAB plays nicely with our existing codebase. Deliver...

Our medical social-networking application is ready for a full shake-down on both iOS and Android. I need every screen and workflow assessed for visual polish, functional accuracy, and cross-device stability, covering the latest OS releases as well as several earlier ones. You will receive the TestFlight build, Admin link and APK link along with a brief feature map.

I am building a React Native or Flutter driver application—think Uber’s driver app, but with no payment or passenger-matching logic. The core requirement is a smooth integration with Waze for turn-by-turn navigation, wrapped inside a secure, professional-grade driver experience. The scope in a nutshell • Account & authentication: drivers create a profile that they can unlock via Face ID, password or fingerprint. During first-time setup the Face ID photo must be matched against the photo on the driver’s license (you may rely on any reliable on-device comparison API or a lightweight server call—open to your recommendation). • Daily workflow: once logged in, the driver starts a “shift”, completes a short pre-trip vehicle checklist, licens...

I’m opening a closed beta on Google Play for my new educational app and need 100 real users to join the tester program, download and install the current build, then exercise it for at least a couple of sessions. The insights I’m looking for focus on overall app functionality, so please keep an eye on how smoothly the navigation flows, how quickly each screen loads, and whether any errors or crashes appear. Because the target audience uses a mix of Android phones and larger-screen tablets, tests must be performed on both device types. To make it easy, I’ll share a private Play Store opt-in link. Once the quota of 100 installs is reached, I’ll close the listing and gather your findings in one structured report. Feel free to supplement written notes with screenshots, ...

A successful engagement will give me: • A fully functioning app compiled and tested on the latest versions of iOS and Android • All project source code with clean, well-commented structure • Brief setup documentation so future updates can be handled smoothly When you respond, focus on the experience that makes you the right fit—projects you’ve shipped, technologies you&rsq...

I already sketched the full flow of the project in Figma (previewable here: ) and now I’m ready to turn that prototype into a working application that runs smoothly on both iOS and Android. The core goal is to let restaurants (or similar vendors) receive, track, and fulfil customer orders in real time.
