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.

The clearest difference is ads: FlowCalendar at none against mini Bubble Level's shown. FlowCalendar also leads on update cadence (every 2 days vs every 4 months). mini Bubble Level's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price and in-app purchases there is nothing between them.
