The open source API sounds really interesting.
It would be awesome if Runalyze would support importing activities one day, as i've been keeping an eye on the Amazfit Stratos for a while too
I thought about it as an interesting addition to my Polar M400.
Didn't even know that there's a v2 announced ... or even available ?? i have to check this ...
edit: mhmmm i'm a little bit confused ... Aren't "Amazfit Stratos" and "Amazfit 2/2S" identical devices?
