## Description

When a frame looks crooked, when you&#39;re mounting a shelf, when you&#39;re leveling furniture — the phone in your pocket becomes a precise spirit level.<br><br>TrueLevel is a level and angle app that uses your device&#39;s tilt sensor to measure level and angle to 0.1°. No complicated setup — measuring starts the moment you open it.<br><br>📐 Level<br>• Auto-switches to a 2-axis circular bubble when the phone lies flat, and a 1-axis bar when stood upright<br>• Manual selection of Auto / Flat / Bar modes<br>• Alerts you with sound and vibration when level is reached, so you don&#39;t even need to watch the screen<br>• Choose the level threshold (±0.1° / ±0.2° / ±0.5°)<br><br>📏 Angle<br>• Shows the absolute angle relative to horizontal<br>• Set a zero point to measure the relative angle between two surfaces<br>• Percent grade (%) display, handy for ramps and pipes<br><br>🛠 Calibration<br>• Quick calibration (1-point): place it on a flat surface and it&#39;s done in about 1 second<br>• Precise calibration (2-point): measure twice with the phone rotated 180° to cancel the sensor&#39;s own bias, staying accurate even on a tilted surface<br><br>✨ Convenience<br>• Hold: freeze the reading for easy checking<br>• Keep screen on, rotation lock<br>• Light / Dark / System theme<br><br>🔒 Privacy<br>• Uses only the tilt sensor. It does not request sensitive permissions such as location, camera, or contacts.<br><br>Recommended for<br>• Anyone installing frames, shelves, or curtain rails themselves<br>• Anyone wanting to level furniture, washing machines, or refrigerators<br>• Anyone needing to level a camping table or RV<br>• Anyone who enjoys DIY and self-decorating<br><br>※ Measurement accuracy may vary depending on your device&#39;s sensor performance and does not replace professional measuring instruments. Calibration before use is recommended.
