Digital Level: Bubble & Angle

A professional bubble level in your pocket. Degrees, slope and a perfectly readable bubble — offline, no account, no tracking.

Digital Level turns your phone or tablet into a professional bubble level, inclinometer and angle meter. Hang a picture, mount a shelf, install an appliance, lay tiles, level a tripod or check a surface — accurate readings are always one tap away.

WHY DIGITAL LEVEL • Realistic bubble level with smooth animation • Digital inclinometer with degrees and slope percentage • Horizontal, vertical and 360° modes • Manual calibration for maximum accuracy • Works fully offline, no unnecessary permissions • Clean, high-contrast UI readable on the job site • Automatic light and dark theme • Optimized for phones and tablets, portrait and landscape

KEY FEATURES • 2D bubble level for flat surfaces (tables, floors, furniture) • 1D bubble level for horizontal and vertical lines (frames, shelves, doors) • Real-time angle and slope meter • Audio and visual feedback when the surface is perfectly level • Quick save of a reference position • Screen lock to read the value without moving the device
