💡 HOW TO USE THE BUBBLE LEVEL
1. Open the app and pick a tool
2. Place your phone on the surface (or against it)
3. Center the bubble – when it turns green, your surface is level

For best results, calibrate once on a known flat surface. Accuracy depends on your phone's sensors; the Metal Detector and Sound Meter need a magnetometer and microphone.
