Bubble Level & Angle Finder

No setup, no sign-up. Open it and it works — calibrated bubble level, angle meter, plumb line and ruler in one. Free to try.

Turn your iPhone into a professional spirit level and angle meter that just works. The Bubble Level starts instantly, locks onto your surface, and guides you to perfect level with precise digital readouts, haptic feedback, and an optional audible tone when you hit your target.

Why it’s better

Auto-level, zero fuss: Open the app and it’s ready. No clutter—just a clean bubble and a big angle display.

Pro accuracy controls: Use the built-in calibration to compensate for cases, magnets, or device variance.

Target the right angle: Snap to 0°, 45°, 90°, or set your own custom angle—ideal for miter cuts, slopes, and repeatable installs.

Feel the perfect level: Haptic feedback (and optional sound) confirms when you’re within your chosen tolerance.

Adjustable tolerance: Fine-tune sensitivity to suit quick DIY jobs or more exacting carpentry.

Clear, high-contrast UI: Easy to read at a glance—on site, in the workshop, or on a ladder.

Perfect for

How it works

Place your iPhone on (or against) the surface you want to level.

Choose a target—0°, 45°, 90°, or Custom—in Settings.

Slowly adjust until the bubble centers; you’ll feel a haptic tap (and hear a tone if enabled) when you’re within your tolerance.

Use Calibration in Settings for best accuracy before critical tasks.
