I still use Movescount. Suunto App is getting better but I am not ready to switch for a number of reasons:
a) Lack of a good web interface like Movescount.
b) Lack of support for POIs and Waypoints
c) Lack of some metrics like cadence, temperature, EPOC, etc
d) Can’t easily copy dozens of my routes from Movescount
e) Would like to be able to sync with two watches
In general I tend to use the app only for the sync and do all the analysis in desktop browser on the web. So the functionality of the app doesn’t matter that much to me, but the platform matters way more.
