Master-Of-Regularity This app is perfect for the classic and sport classic uniformity rally. In a single app, the 7 most important applications for oldtimer rally are included: 1. Synchronized clock with GPS, atomic time or manual. 2. a stopwatch with a split-precision of 1/100 second 3. countdown with a Split-precision of 1/100 second with Beep or Speech in 3 languages (de, en, it) 4. tripmaster 5. speedmeter that shows you the average speed of the test 6. Speedpilot 7. Speedometer There is no limit on the number of stages/sectors. The biggest advantage over other Apps is that you can run multiple tests at the same time, such as a test inside a test. At the end of a stage and press the reset button, a log file is always saved. The LogFile can: 1) be sent by e-mail. 2) be opened as a table. 3) be seen as a route in Google Maps. The "Head-Up-Display" function is optionally available via the settings. This allows the mirrored display to be projected onto a windshield. Added the function "Share display". Share the display with a second smartphone/tablet so that the driver also sees the data from the current test. * GPS/GNSS This app uses GNSS if it is supported by the device. GNSS is a collective term for the use of existing global satellite systems such as: GPS, GLONASS, Galileo, Beidou. * Distance measurement with wheel sensor (sensor-kit) or GPS The app can evaluate / measure the distance traveled with a wheel sensor or with GPS. Please note that GPS can only provide reliable measurements on open terrain. Therefore, please do not write any negative reviews if the app cannot provide reliable measurements in such cases. For this reason I recommend the use of a wheel sensor (sensor kit) for mountain areas. For the start can be used of an external Bluetooth-device.

Verdict
