Inclinometer HD is a high-tech tool for determining angle and trueness. A high precision calibration system coupled with a clear, responsive rotating interface result in the best angle measurement system on the app store.

The interface includes easy to see markings indicating major angles of interest, a rotating degrees angle readout, a high precision fixed readout including degrees, radians, and major ratios of pi. Two separate angle lines, one vertical and one horizontal, allows easy determining of trueness and alignment.
