Bubble Level: Angle & Tilt

Bubble Level turns your iPhone into an accurate spirit level. Hang a picture straight, level a shelf, check a slope or set up a tripod — the reading is steady, easy to read and ready in a second. SIX WAYS TO MEASURE • Level — a classic vial with a large, clear reading. Turn the phone on its side and rest it against a wall; the screen turns with it. • 2D — a round bubble that levels both directions at once, for tables, appliances and tripods. • Angle — a protractor-style readout for measuring any tilt. • Camera — a live viewfinder with a tilt crosshair for lining up photos and objects. • History — save readings and add a note so you remember what you measured. • Settings — make the level work the way you do. FOUR LEVEL STYLES Classic, Vial, Ring and Horizon. Swipe on the Level screen to switch between them. PRECISE AND STEADY • Calibrate against a known flat surface • Filtered sensor readings, so the bubble doesn't jitter • Hold freezes the current reading; Zero measures relative to any surface • Degrees, slope percent or millimeters per meter, with 0–2 decimal places • Adjustable level threshold, and a pass/fail tolerance for saved readings MADE FOR THE JOB • A soft click and a vibration the moment you reach level • Keeps the screen awake while you measure • Light and dark theme • Available in more than 70 languages Bubble Level is free and supported by ads.
