3pMaster: Tripmaster Roadbook

A precise GPS tripmaster built for serious off-road, overland and rally driving — measure every meter, follow your roadbook, and keep your eyes on the trail. Trusted by off-roaders, overlanders and ralliers since 2013. 3pMaster turns your iPhone into a dedicated odometer. Track partial and total distance, follow your paper or printed roadbook, and let the app call out the numbers so you can focus on driving. IN YOUR LANGUAGE Fully localized in English, German, Spanish, French, Italian, and Dutch — built with real rally terminology, not machine translation.

Continued GPS use in the background can decrease battery life. Looking for iPad support and on-screen timers? See 3pMaster Pro, the universal version.
