This app is only available on the App Store for iOS devices.

Overview of Operation
Recorded data is saved as Runs. Each Run starts when the vehicle exceeds 20MPH/33KPH and ends when the vehicle is moving slowly. The run includes several seconds of data before the recording trigger speed is reached. This way the start of an auto-cross run is included.
External GPS Modules
Due to limitations of the built-in GPS module, the data may suffer from inaccuracy. An external GPS module is recommended for improved accuracy.
Continued use of GPS running in the background can dramatically decrease battery life. Use of a power adaptor is highly recommended.
