    ...for both iOS and Android. The job is straightforward: load the existing site inside a reliable WebView so users get the exact same experience they have in a browser, but from a branded app icon on their phone. Key things I want handled: • Clean WebView implementation that respects all current site functionality, including checkout, log-ins and embedded media. • Automatic scaling so pages remain responsive on the wide range of device sizes. • Standard mobile app elements—splash screen, app icon and a back/forward navigation solution where appropriate. • Proper handling of external links (so they open in the system browser) and in-app links (stay within the WebView). • Builds ready for submission to both Ap...

    I’m rolling out a smartphone app that collects product descriptions for our catalogue and I need an extra pair of hands to keep the flow moving. All the data you’ll enter is plain text—no numbers, images, or odd formatting—just clean, well-written descriptions supplied to you in a shared document. You’ll be typing everything directly into the app from your phone (Android or iOS both work), so good mobile-keyboard speed and accuracy are essential. Because this is entirely manual input, I’m counting on your attention to detail: consistent spelling, correct punctuation, and adherence to the short style guide I’ll provide. A brief onboarding call will walk you through the interface and the submission workflow; after that you can...

    I’m building a truly mobile-first energy management system that must run smoothly on both iOS and Android from day one. The app will let end-users watch their energy usage in real time, control connected devices remotely, and pull clear consumption reports, all from their phones. Authentication will rely on a classic email-and-password flow reinforced by a one-time verification code before access is granted. I’m open to expanding to social or biometric login later, but they are not part of this initial scope. Beyond the three core features above, I also need: • Behaviour-pattern monitoring to surface efficiency tips and anomalies • A financial registration module, ready to plug into a payment interface when required • Continuous status/e...

    ...complete ChaloTrain source as a ZIP. Your first task is to open the project in Android Studio, iron out every build error and bug, and verify that the app name, icon, package ID and other Android-specific settings are correct. Once the code compiles cleanly I need both a release-signed APK and a Play-ready signed AAB. I have gone through Play Console once before, so I know the basics, but I’d like you to take the lead this time—create or update the listing, upload the bundle, handle content ratings, privacy policy links and any review feedback, and stay on the job until the status reads “Published”. Deliverables • Project configured and building without errors • Release-signed APK and AAB provided • App success...

    I’m ready to turn my game concept into a polished Android application and need a developer who can take the project from first prototype to Google Play release. The core objective is simple: build a fun, stable, and performance-optimised gaming app exclusively for Android phones and tablets.

I already have draft gameplay mechanics and artwork; you’ll weave these together, advise on the best engine or native stack (Unity, Godot, Kotlin + OpenGL, etc.), and keep frame rates smooth across common mid-range devices. Deliverables • One signed, installable APK ready for internal testi...

The end goal is a reusabl...Source presets or checkpoints for maintaining character appearance across episodes or campaigns. Acceptance criteria • Same character model matches reference stills at ±1 pixel tolerance across every shot. • Voice fingerprint deviation ≤ 3 % on standard speaker-verification metrics for clips up to 10 minutes. • Rendered clips play without desync on a vanilla playback test (VLC, Safari, Android). If you already ship bulletproof talking-head systems and can demo an end-to-end run tonight, message me (908-204-6313 is fastest). Let’s lock ...
