3pMaster: Tripmaster Roadbook

Now in 6 languages with a redesigned dashboard. Bigger, clearer numbers, voice announcements, and iCloud sync for your tracks. Built for ralliers and co-drivers.

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.

Note: 3pMaster needs an iPhone with GPS. A data connection is only needed for maps. Continued GPS use in the background can decrease battery life.
