Could you build this?
Partial Developing reliable app blockers requires OS-level privileged APIs such as Apple's Screen Time/Family Controls API or Android Accessibility/UsageStats, which have strict platform-specific constraints.
What it would actually take: Implementation requires native mobile development (Swift for iOS or Kotlin for Android) interfacing with low-level device management APIs (ScreenTime framework and DeviceActivityMonitor on iOS). The hard part is managing OS lifecycle constraints, preventing easy bypasses, maintaining offline persistence, and navigating Apple's stringent entitlement approval process for Family Controls. It requires experienced native mobile developers who understand OS-level daemon behaviors.
