RallyBlitz Nav App Reviews

Works great after the last update. Accurate and very easy to use. $20 may sound a lot for an app but it's better than the ICO Rally MAX-G.

This app works as a Rally Odometer and is absolutely spot on! Well worth the $20 and eliminates the need for wheel sensors and calibration. I have used it as a backup for my ICO and as a stand alone odometer with zero problems. Make sure to turn the brightness down on your iPhone to preserve battery.
