About this app

Grelt Gauge is a pocket measuring bench. Four tools, no setup, works offline.

Tools
1. Ruler — on-screen scale in millimeters or inches. Calibrate once to your display, then measure small objects against the edge.
2. Angle — a protractor driven by the tilt sensor. Live needle, tap Hold to freeze a reading.
3. Level — a two-axis bubble level. Turns yellow within one degree of flat, with a short vibration when it lands.
4. Timer — a stopwatch with laps, plus a countdown that buzzes at zero.

Facts
- Offline. No network calls.
- No account, no ads, no sign-up.
- Calibration and preferences are saved on the device.
- Phone portrait layout, light and dark themes.
- Vibration is used only for the level and the countdown.

Notes
- Sensor readings depend on your device hardware; a level surface helps calibration.
- To calibrate the ruler, line it up with a known size — a bank card is 85.6 mm wide.
