Bubble Level turns your phone into a clean, precise level tool for quick alignment checks at home, on site, or anywhere you need a straight reference. Use it as a classic spirit level, a flat surface level, a plumb guide, or a camera angle finder with live visual guides. KEY FEATURES • Bubble Level — check horizontal and vertical alignment with a clear digital bubble display. • Flat Surface Level — place your phone on a table, shelf, appliance, or workpiece to see roll and pitch together. • Plumb & Angle Tool — measure off-plumb angles and slope in degrees or percent. • Camera Level — align objects through the live camera view with horizontal or vertical guide lines. • Calibration Profiles — calibrate each phone surface for more reliable readings, then save profiles for different cases or setups. • Save Measurements — keep important readings for later and share them when needed. • Screenshots & Photos — capture your level checks, including camera alignment photos. • Custom Display — choose units, decimal precision, alert range, colors, vibration, and sound feedback. HOW IT WORKS Open the tool you need, place or hold your phone against the surface, and read the live angle instantly. For best accuracy, run the guided calibration on the surfaces you use most often.

Accuracy can vary by device, case, magnetic interference, sensor condition, and calibration quality.
