Bubble Level-Spirit Level Tool

About

Transform your iPhone into an ultra-precise dual-axis spirit level and angle inclinometer. Whether you are hanging wall pictures, aligning furniture, leveling an RV camping vehicle, setting up a camera tripod, or checking construction slopes, this app delivers industrial-grade precision with tactile realism. KEY FEATURES Realistic Dual-Axis Physical Gauges • Circular Bullseye Surface Level: 360-degree omnidirectional pitch and roll leveling for tables, shelves, countertops, and appliances with concentric degree guide rings. • Fluid Spirit Vial: High-contrast tube with realistic physical bubble dynamics for edge alignment, plumb-line vertical checks, and woodwork. Patented 180-Degree Reversal Zero-Drift Calibration • Uneven phone cases, protective bumpers, or protruding camera bumps? No problem! • Perform a quick 180-degree rotation on any flat surface: our reversal algorithm calculates and eliminates sensor drift and hardware bias instantly, revealing the true absolute level of the surface. Automatic Seamless Edge Detection • No manual switches needed! Hold your phone vertically for instant short-edge leveling. Turn it horizontally, and the app automatically switches to an ultra-wide landscape cockpit long-edge level. Eyes-Free Acoustic Audio Guidance • Level by sound without staring at your screen! • Geiger Clicker: Pulse frequency accelerates as you get closer to 0.00 degrees. • Pitch Glide: Smooth audio frequency glide indicating tilt direction. • Crisp audio chime & gentle haptic pulse upon reaching perfect level. Includes an instant global mute button in the top bar. Camera Live Inspector & Construction Watermark • View live camera feed with an overlaid crosshair horizon line and 3x3 composition grid. • Perfect for hanging large wall art, curtain rods, projection screens, and checking doors or windows. • Capture photos with certified measurement watermarks including timestamp, tilt angle, GPS location, and inspector notes. Professional Slope & Angle Units • One-tap instant toggle between Degrees and Slope Percentage (%). • Tare Zero (Relative Angle): Zero out any slope or incline to measure angles relative to an existing surface. 4 TAILORED SCENARIO PRESETS Picture Hanging: Edge alignment with sensitive vibration and chime guidance.
