In my opinion the app is quite useless, because of different reasons:
I like your new platform, but i really would appreciate if i had the possibility to publish my uploaded tracks (e.g. from my Garmin or TomTom device) into the acitivities instead of using my smartphone (date of tour should be editable then). And to upload photos as moments from the PC, because i simply don't want to use the smartphone app.
The tracks of external devices only showed in Profile > Tracks.
It is not possible to show on the timeline and activities.
Most people do not use the track function on their devices, start it, end it, connect to PC, upload it, etc, etc.
With the app it al goes automaticily.
The samsung has a bad battery, I had the same and used a powerbank.
With my new iPhone it is not a problem anymore.
Yes, thanks for the tips and we take a serieus look to it.
