Bubble Level & Clinometer

Bubble Level is a precision digital inclinometer, spirit level, and angle finder designed for craftsmen, builders, DIYers, and engineers. Engineered with a clean, high-contrast industrial aesthetic, it delivers responsive, low-latency measurements in both Portrait and Landscape orientations. Measurement Modes:
 • Surface Level: dual-axis circular bullseye level displaying tilt, pitch, and roll readouts simultaneously.
 • Edge Level: measures angles along any physical edge (top, bottom, left, right) with automatic detection and edge locking.
 • Angle Mode: accurate inclinometer with support for absolute level and relative angle comparisons. Core Features:
 • Relative Zero: zero out any reference plane to measure relative slopes and angles effortlessly.
 • Hold Function: freeze current readings on screen when working in awkward or tight spots.
 • Acoustic & Haptic Guidance: audio beeps and vibration feedback trigger when hitting the target level within your defined tolerance.
 • Multiple Engineering Units: Degrees (°), Grade (%), Pitch (in/ft), and Roof Slope (mm/m).
 • Comprehensive Calibration Wizard:
 – Instant single-tap zero point calibration.
 – Two-step reversal calibration that automatically eliminates camera-bump bias.
 – Edge-by-edge calibration for all four sides of the phone.
 • Measurement History: save, review, and manage your angle measurements with timestamps.
 • Private & Offline: works fully offline without requiring an internet connection or sensitive device permissions.
