About this app

Bubble Level & Spirit Level turns your phone into an accurate spirit level, plumb bob and angle finder — no ads, no tracking, nothing collected.

Check if a shelf, floor, picture frame or countertop is level, or if a wall or door frame is perfectly vertical. Big, easy-to-read numbers work from across the room, so it's built for real jobs, not just a novelty.

• Level mode — rest the edge of your phone on a surface and read the horizontal tilt
• Plumb mode — hold the phone upright to check vertical alignment
• Flat mode — set the phone flat and watch the bubble move on two axes
• Camera mode (Pro) — level guide lines over the live camera image

Measurement tools:
• Save readings and pull them up later (3 free, unlimited with Pro)
• Lock the current value to compare it against a new surface
• Relative zero (Pro) — set any tilt as a new "zero" reference
• Units: degrees for free, or switch to %, in/ft, mm/m with Pro

Calibration that matters: phone sensors drift, so we built a full 6-direction, 2-position calibration routine, with a warning if your phone isn't calibrated yet. Keep one profile for free, or save up to 3 with Pro — handy if you switch between a bare phone and one in a case.

Alerts and appearance:
• Visual alert when you hit level, free
• Sound and vibration alerts with Pro
• Dark theme, free
• Custom theme color with Pro

Privacy first: no ads, no analytics or tracking SDKs, and no data collected — the app simply doesn't ask for it. Camera access is only requested if you open Camera mode.

Pro unlocks camera mode, relative zero, extra units, extra calibration profiles, sound/vibration alerts and theme colors, as a single one-time purchase. No subscription, no renewal.

Available in 23 languages.
