⎜ 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 modules, the data may suffer from inaccuracy. An external GPS module is required to record accurate data for high speed driving events.

Value purchase app Am giving 3 stars bcuz a s/w bug has been identified. With vidoe recording on, the software is only able to log 2 lapsof video before cutting itself off. This did not use to happen. Otherwise, the app would have deserved at least 5 stars.

This app works. It looks like it was written for Android 2.2. The look and feel could use a lot of maturity. The logs only put out 1 GPS data point per second, while the competitor app Harry's Lap Timer shows the full 10hz. Support has not yet replied to my questions. For an app this expensive, I expect a premium user interface and support.
