Does anyone know of a reliable Pedometer app that meets the following criteria? I am looking for a good pedometer app that I would like to use therapeutically to determine the actual daily walking distance. However, it should meet the following criteria: 1. Distance measurement with GPS, because apps I tested only determined the number of steps relatively precisely via sensor and estimate the distance by means of estimated!!! step length. The differences between these apps were considerable. 2. Since I take the tram between my "walking exercises", the app has to recognize this and pause automatically. After all, I don't feel like fumbling the phone out of my pocket, unlocking it and pressing Pause or Start each time. The apps I tested (Pacer, Runtime, "Walk with Map My Walk" & "Pedometer Step Counter Weight Calorie Tracker") didn't do that and that's why I'm asking here now. 3. A small extra bonus would be if the GPS deactivates itself when no "walking activity" is detected. That would save battery but I can also switch it off manually. PS: Free or paid, both are welcome. If the app does it's job, a few bucks for it don't matter.
