Y-Inclinometer by Dr. Jukka is a simple app that displays vehicle angle while off-roading or climbing a bridge, or while simply driving in India! Just fix your phone in a secure cradle andngle it so that it is perfectly upright in your vehicle. Then launch the app!
But make sure that you don’t lose your bearings and flip your vehicle while enjoying some off-road fun. And don’t do anything stupid like testing Y-Inclinometer’s readings to the limits - that could tilt things too much for your car to handle!!
-->Download<--P.S: After installation the app won't show in the regular application menu, it will be in a new folder named as "Dr.Jukka.com". Have fun!
