3 stars: The app tracks my routes, time and speed etc. But it is very disappointing that activities only show up in your weekly done sports when it's running, cycling or swimming. I prefer skating as cycling is something I already do a lot and running sucks. But now it seems as though I've done nothing if I don't run, even though I do a lot. Wish that it'd be changed that you could choose what activities are counted towards your weekly activities.
4 stars: It is a great place for keeping your sports data over time cross-device. It took me a while though to figure out that it was not meant to record the sports themselves with this app. For example a polar h7 cannot connect. Furthermore I think pace is fundamentally less useful than speed, both for my intuition as for graphing purposes. I will keep calculating the speed myself
