mini Bubble Level vs Bubble Level + Compass

A simple level for everyday jobs. Check a shelf, straighten a picture frame or find the tilt of a table without searching through a busy screen. • See the horizontal and vertical levels together on the main screen. • Read angles in degrees or slope as a percentage in the Angle & slope tool. • Place your phone flat on a surface to check its tilt in both directions. • Choose a target angle and align to it with visual and haptic feedback. • Set a reference to compare the angles of two positions. • Hold a reading, move your phone and read the result. Resume when ready. • Use a clear light or dark appearance. The screen stays awake while the app is in use. • Use camera guides to align your frame while reading the phone’s horizontal and vertical tilt. • Start a 3-second timer, place the phone and hold the reading without touching it again. • Find held readings in Recent measurements, with both axes and the date and time, stored on your device. The measurement tools are free to use, with no subscription or Pro tier. The app displays banner ads. Measurements use your phone’s motion sensors and are approximate. Place the phone firmly against the surface; a case or camera bump can affect contact. Slope percentage is undefined at a vertical position. Use a suitable physical instrument when a job requires verified accuracy. Camera alignment shows the phone’s tilt; it does not measure an object’s angle or distance from an image.

Bubble Level + Compass combines a bubble level and a compass, with advanced controls for users who want more than the basics. Use it to check horizontal/vertical/surface angles, or get compass direction relative to either true or magnetic north. For users who work with physical compasses, magnetic declination is also provided to convert magnetic readings to true north readings. The level includes gyroscope calibration, which is especially useful on phones with a raised camera bump or an uneven back/case. No nagging popups or interruptions. The free version only includes a small banner ad at the bottom. Features • Bullseye level plus horizontal and vertical levels with 0.1 degree precision. • Compass with true north and magnetic north. • Magnetic declination display for converting magnetic readings to true north readings. • Gyroscope calibration for phones that do not rest perfectly flat. • Gyro or accelerometer sensor mode. • Clean interface with no popup interruptions.

An ad-free Pro version is also available, with more features including Apple Watch support, night mode, slope/inclination %, and pitch, yaw, and roll rotation rate.
