Tilt Hit

■ Whose angle sense is sharpest? ■

Tilt Hit is a simple angle-guessing game played entirely with your phone's tilt. Hide the screen, tilt to what feels like the target angle, and see how close you got — using only the device's gravity sensor (CoreMotion).

No special equipment, no internet, no camera. Pure physics versus your gut feeling — solo, or pass the phone around with friends.


■ How to Play ■

1. Place your phone flat on a table and tap CALIBRATE / RESET to record 0°
2. Pick a target: 30°, 45°, 60°, or 90°
3. Tap START — the screen goes dark (or light, in Soft theme)
4. Lift your phone and tilt to what feels like the target
5. Tap the screen — see your measured angle and the Δ (error)
6. Get within 1°? Perfect! Within 3°? Great!


■ Key Features ■

● Pure tilt-based gameplay
Uses CoreMotion to track your phone's tilt with high accuracy. No camera, no AR — just raw physics and your intuition.

● Great with friends
Each round takes seconds, so it's perfect for taking turns and competing for the best score. The look on someone's face when they nail "Perfect!" is half the fun.

● Two visual themes
Switch instantly to fit your mood:
・Cyber — neon green cyberpunk look (dark background, monospace)
・Soft — warm cream world (light background, rounded type)

● Fully offline
No network connection required. Nothing collected, nothing transmitted. Privacy by design.

● Quick & rhythmic
Each round takes seconds. Perfect for a coffee break or a competitive moment with friends.
