Gradient level reads the current slope as a percentage. Often used on roads and railroads to indicate the steepness of a grade. Many model railroaders use this while building layouts.
Gradient level works in auto mode to read the grade from any of the 6 sides of a device automatically. It can optionally be locked to read from the right or back side. Each side can be calibrated independently of the others.

Ratings and Reviews
If you are building a model railroad, it is very important to keep the inclines within a realistic range. This app has made it very easy to do this. You simply place your iPad or iPhone on a known level surface, push a button to calibrate and you are ready to go. As far as I can tell, it is extremely accurate.
I was ready to spend around $75 for a device that does the same thing when I heard this was being developed. I highly recommend this (and their other apps), for anyone interested in model railroading.
Beautifully simple; does what it says; accurate. Sure beats spending $40 on a dedicated digital slope meter!
