My main concern going in was whether or not the app would torch my battery (I’m looking at you strava and map my ride) as I frequently ride over 5-6hrs at a time. Im not sure what the developers are doing behind the scenes with this app but it is by far the most power efficient GPS app i have tried. It works so well I started using it for running & hiking in addition to cycling. The turn by turn nav is done very well (esp coming from meh garmin devices) and the application is intuitive and easy to use. Love the service, and the app really adds a whole new dimension to it.
