Would it be possible to implement a low battery alert at the start of tracking, or perhaps a battery level indicator?
I have a Polar device, and sadly several times the battery has run out before the end of the night so I end up with a blank stretch.

I don’t think I would be possible as too many different watch existing and supported…
But the best is to always check battery few hours before time sleep…
This way you could charge a few to get enough for the night…
Personally I check twice a day and I’m having a 3 days battery life…
