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.
