Read the full description
Sundial is a screen time app built on one idea: a limit should feel like a sundial, not a stopwatch. You decide what your time is for, and the app quietly holds the line. Choose the apps or categories that eat your day and give each rule a daily allowance. When it runs out, iOS itself blocks the app — not a timer you can swipe away. Everything is on your local iPhone. No account, no server, no ads, no subscription. Free for most features, only a one-time in-app purchase.

Partial The rule and allowance UI is easy to vibe-code, but the core blocking depends on Apple's Screen Time APIs (FamilyControls and ManagedSettings). Those require a native Swift app and an entitlement that Apple must approve.
What it would actually take: The app needs a native SwiftUI app with the FamilyControls, ManagedSettings, and DeviceActivity frameworks, plus Apple's approved entitlement for distribution. Reliable enforcement across restarts, schedule edge cases, and iOS version changes requires real iOS platform knowledge and App Store review experience, which AI assistance only partly covers.
