I’m building a new Android-only social networking app whose standout feature is strong, built-in user safeguards. The first release doesn’t need every bell and whistle; what matters is that people can interact normally while staying protected by the following controls: • User blocking – a single tap must hide all content and prevent further contact. • Usage time limits – daily caps stored server-side so a reinstall can’t reset the clock. • Content restrictions – category filters that keep unwanted posts out of feeds and search. If you can deliver that foundation along with a basic sign-up/login flow and a lean feed UI, we’re good for the MVP. I’m happy with Kotlin or modern Java and standard Jetpack components; alternate stacks such as Flutter or React Native are fine too as long as the restriction logic remains tamper-proof and the APK stays lightweight. Deliverables 1. Complete Android Studio project with readable, well-commented code. 2. Test-ready APK. 3. Short README outlining architecture and exactly how you enforce blocking, timers, and content filters. When you reply, let me know which libraries or backend you’d use for secure auth and persistent settings, plus any prior work where you implemented similar moderation or parental-control features.
