Spirit level and Plumb line

About

Turn your phone into a precise, reliable tool for measuring tilt angles and checking surfaces. This app combines the classic functionality of a bubble level and plumb line with modern digital capabilities. Key features: • High measurement accuracy: Uses your device's sensors to determine tilt in degrees, radians, or percentages. • Two-position calibration: A unique calibration feature (at 0° and 180°) ensures maximum accuracy, even on devices with sensor deviations. • Audio and vibration feedback: Get instant feedback when a surface is perfectly level, without needing to look at the screen. • Continuous audio signal: A "smart" sound feature changes the tone based on the tilt angle, helping you level objects by ear. • Measurement history: Save recent measurement data to easily track your work. • Stability indicator: A built-in algorithm signals when the readings have stabilized, ensuring the most accurate capture. • Flexible settings: Customize sensitivity (tolerance), units of measurement, and visual themes to suit your needs. Who is this app for? • Builders and tradespeople: For installing furniture and leveling walls, floors, and structures. • Photographers: For perfectly leveling the horizon when shooting on a tripod. • Car enthusiasts: For checking vehicle tilt when parking or setting up a camper. • DIYers: For hanging pictures, shelves, and TVs straight. Why "Pro Level"? We focused heavily on stability and a simple interface. The app is free of clutter, runs quickly, and—once properly calibrated—delivers accuracy comparable to professional tools. Make your next project perfectly level with the Pro Level!
