App Description

A professional clinometer / bubble level for mobile devices.

ProLevel measures and displays the angle of your device against gravity, with the maximum accuracy that the internal sensors permit.

FEATURES:

- Minimalist, precise, to-the-point design: you won't find animated photorealistic bubbles anywhere in this app!
- Measure the tilt of surfaces, picture frames etc. accurately. Can be used while the device is lying flat on a surface, or in landscape orientation with one of the longer sides on the surface to be measured.
- Audio Feedback: dual-axis advanced audio feedback with separate tones, for using the app without looking at the display.
- Selectable Ranges and Scales (linear or logarithmic).
- Selectable Tolerance: choose the maximum inclination that is considered flat, both for visual and audible indication.
- Advanced Calibrator: very accurate, calibration is possible even on non-level surfaces.
- Adjustable Averager: eliminate erratic readouts from vibration, or measure the average inclination over time.
- Peak Hold: visualize the entire range of inclinations that were measured over time.
- In-App help.

Accuracy / Legal notice

In our experience, measurement error is roughly +/- 0.3 degrees, mainly due to drift. Please note that for legal reasons, we need to explicitly state that this app is not "meant for professional use", even though we are convinced it is one of the most "professional" (in terms of features / readout accuracy) apps of this kind in the App Store.
