You can’t do any of that from the Suunto App for your Ambit. And never will be it seems at this point. Only syncing of activities as it stands today and going forward.
1 and 2 will be supported by some other MovesCount-ish application, according to Suunto sometime mid 2020. Not likely to be a mobile app. Probably something web based with bridge software on your pc/Mac like suuntolink. We shall see.
3 looks like it’ll never exist once MovesCount is discontinued completely. Folks have asked for a web/browser platform for analysis. Nothing has been announced or planned afaik. But the Suunto App is the platform for syncing recorded activities and analysis. There are also third party tools for the analysis once you’ve synced to the Suunto App.
