Bubble Level — Spirit Level

Bubble level & tilt meter — precise spirit level with calibration

Bubble Level turns your phone into a precision spirit level. Place it on any surface and instantly see if it's perfectly flat — the bubble centres and turns green when you're level.

FEATURES
• Real-time bubble — smooth, responsive level indicator using your phone's accelerometer
• X/Y tilt readout — see exact degrees of tilt in both axes to 0.1° precision
• Perfect Level indicator — bubble turns green and banner confirms when within ±1°
• Zero / Recalibrate — set any surface as your reference point with one tap
• Clean, distraction-free interface — no clutter, works in portrait and landscape

PERFECT FOR
• Hanging pictures and shelves perfectly straight
• Checking that furniture, appliances, and worktops are flat
• Leveling a camera tripod or workbench
• DIY projects, home improvement, and renovation work
• Tradesperson quick checks on-site

HOW IT WORKS
Your phone's built-in accelerometer detects gravity to calculate the precise angle of tilt. A low-pass filter smooths out hand tremors for a steady, accurate reading. The bubble responds in real time — no calibration needed to get started.

Open the level, place your phone, and check the surface in seconds.
