Seems to work fine.

I think that it needs some work. It reacts too much to heavy breaking. If I stop fast it will set the alarm off even on flat roads. If you are going slow like most people would in a situation you would really need it I would say it should work good for that. If you are going fast on a hill you wouldn't be looking at the phone.

the warning alarm goes off all the time even when I'm on level ground and the "audible alarm" is turned off please fix this besides that works pretty well

I bought this for off-roading in terrain that can seriously result in a flip, not for trail riding. When I'm climbing hills or crawling over rocky obstacles I don't like to listen to music, so the inability to control my music from within this app wasn't important to my buying decision. What was important was a simple interface that is easy to read at a glance and the ability to customize the inclinometer's settings for my particular vehicle. Both of these are handled well in this app. Tilt and roll alarms can be adjusted independently and the display for each can be reversed to suit your preference. The level settings are remembered so you don't have to calibrate the app every time you launch it (great if you mount your device in the same cradle every time you use it in the car). Auto-lock can be disabled (a must unless you want to fiddle with your iOS device while you drive) and the vehicle icon can be easily swiped between various off-road and utility trucks (although I'd like to see a basic Cherokee added to the lineup).How can you go wrong for a dollar?
