It just show you the track and the distance you traveled on a map. There are no additional information's available from the engine e.g. like the status of the battery at the beginning of the trip and at the end of the trip, you can see that on the small screen of the engine but not in the app. You have to buy an expensive extra cable to connect your phone via BLE with the engine. Sometime this extra cable disturbed the normal communication between the battery pack and the computer of the Travel 1003 so you might see an Error Code 32 on the display. Overall the application does not provide any added value compared to other cheaper solutions for tracking.
I had a torquedo a couple of years ago and they didn't have this app
Great app for Ultralight 403 Love to keep track of distance and range!
