I'm building a lightweight, no-frills utility app for Android—think along the lines of a calculator or simple productivity tool that lets users get a task done quickly without ads, social feeds, or sign-ups. I have the core concept sketched out on paper, but I need an experienced Android developer to turn those sketches into a polished, Play-Store-ready application. What I’m after • Native Android build (Android Studio with Kotlin or Java—whichever you’re most comfortable with). • Clean Material-design interface that scales from Android 8.0 upward. • Smooth offline performance; the app should start instantly and work without network access. • Solid, well-commented code so future updates are straightforward. • Basic analytics hook (Firebase or a comparable lightweight solution) to track feature usage. Deliverables • Compiled APK for testing and final release. • Complete, organised source code in a Git repository. • One-page build/setup guide so I can recompile locally. • Brief user manual outlining core screens and functions. Acceptance criteria 1. App installs on devices running Android 8.0+ with no crashes during normal use. 2. All primary functions operate within 200 ms response time on a mid-range phone. 3. UI passes Google’s accessibility scanner with no critical issues. If this sounds like a good fit, tell me how you’d tackle the project, which libraries you prefer, and an estimated timeline from kickoff to Play Store submission.
