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—just a lean prototype I can test and iterate on. If you can deliver quickly, document your code, and hand over the project files, let’s get started.
