Read full description

Check a shelf, align a frame or compare an angle with a realistic spirit level designed for iPhone and iPad. THREE MEASURING MODES Surface checks a flat surface in two directions. Straight checks an edge horizontally. Plumb checks forward and backward lean when the back of your device rests against a vertical surface. CLEAR READINGS Read angles in degrees, percent or millimeters per meter. Freeze a reading with Hold, use optional haptic feedback and calibrate against a known reference or with two positions. Target angles, relative measurements and Auto Hold help with more detailed checks. BUBBLE LEVEL PRO One purchase unlocks all eight material themes, the 3-in-1 display and Camera Level. Add live alignment guides to the camera view, capture a photo with the measurement, then save or share it. No subscription. Restore your purchase on your iPhone or iPad using the same Apple Account. YOUR LANGUAGE, INCLUDED English, Dutch, German, French, Spanish, Italian, Portuguese, Polish, Turkish, Japanese, Korean and Simplified Chinese. All languages are free. Measurement uses the device's motion sensors. Camera Level measures device tilt, not a wall's forward lean from a photo. Stable contact and calibration matter; keep buttons, cases and the camera bump clear of the reference surface. Sensor readings stay on your device.
