iPhone
A calm, accurate bubble level for your phone: four level styles, a 2D bubble, an angle finder and a camera level, with calibration, hold and saved readings.
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.
