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 current Android versions. Here’s what I expect: • A minimalist user interface that follows standard Material Design guidelines. • Core screens wired up and working so I can validate the basic workflow. • An installable APK plus full, well-commented source code. • Clear instructions for building and running the project in Android Studio. Please choose libraries and architecture you’re comfortable maintaining; Kotlin with Jetpack components is preferred but Java is fine if that fits your workflow better. Once I review the draft build, we’ll identify any small tweaks needed before final hand-off.
