Could you build this?
Partial The focus timer, UI, and gamified coral growth mechanics are straightforward to vibe-code, but reliable system-level app blocking and deep content inspection on Android (like selectively blocking YouTube Shorts) require tricky accessibility service hacks and OS-level permissions.
What it would actually take: The app needs a native Android stack (Kotlin/Jetpack Compose) leveraging an AccessibilityService and UsageStatsManager to inspect active window content and detect specific view hierarchies (such as YouTube Shorts fragments). The hard part is maintaining continuous background execution across diverse Android OEM battery-killing profiles and adapting UI scraping logic when target apps change their layouts. It requires Android platform expertise and continuous maintenance against OS policy changes.
