TempoMaster: GPS Speedometer/Odometer & Car Finder

Offers in-app purchases

Easily avoid speed-related incidents with TempoMaster!

Now with Vmax planner

Drive any course of your choice and set up your own speed signs at home on the map.

TempoMaster is an offline GPS speedometer that displays in realtime your current car speed and the maximum allowed speed for that zone. Many navigational apps don't have speedometers included (i.e. Google Maps), thus TempoMaster is an excellent addition that helps you respect the law and avoid any radar fees.

It integrates perfectly with other navigational maps as it can be shown overlayed on top of other apps. The realtime data is provided by OpenStreetMap (OSM) and you can also make direct edits in the private Database from TempoMaster. Can be started offline and even via Bluetooth.
