About this app

Bubble Level turns your phone into an accurate spirit level and angle finder, with a real-size ruler built in. Hang pictures straight, level shelves and furniture, set up a washing machine or check a slope, all without a toolbox.

Surface level
• Lay the phone flat: a round bubble vial shows tilt in every direction
• Exact X and Y angles, plus the total tilt
• Beep and buzz the moment it is level

Edge level
• Stand the phone on any edge and it becomes a bar level
• Works on the long or short side, for frames, doors and worktops

Accurate
• Calibrate on a known level surface in one tap, even with a case on
• Degrees or slope % for ramps, drains and roofs
• Hold freezes the reading so you can read it in awkward spots

Ruler
• A real-size ruler along the screen, in centimetres and inches
• Drag the line to measure small objects

Bubble Level Pro
One payment removes all ads and unlocks precise mode with readings to 0.01°. Or watch a short video to use precise mode free for 24 hours.
