Tiltwell 틸트웰
Tiltwell is a bubble level, angle finder and on-screen ruler for Android, drawn as real tools. Every vial, bezel, dial and bubble was rendered in Blender and layered in the app, so the bubble drifts and settles in its liquid behind real-looking glass. Lay the phone flat for a round bullseye level, stand it on an edge for a bar level, switch to a protractor dial for angles, or measure small objects with a calibrated ruler. Two-step reversal calibration removes the tilt between the sensor and the phone's case. No ads, no account, no tracking.

What makes it different
- Pre-rendered 3D tool layers (body, liquid, bubble, glass) composited live, so the bubble sits inside the glass instead of on top of a flat picture.
- The bubble moves like a bubble: a damped spring follows a smoothed gravity reading, steady when the phone is still and quick when it moves.
- Calibration that matches how a carpenter checks a level: measure, turn 180° on the same spot, measure again.
- Five skins change every tool at once; any skin can be tried for 15 seconds before buying.
