I'd love to hear if anyone has suggestions with an additional feature:

- No internet access / sign up / data syncing to the cloud is required (ideally it wouldn't exist at all). The ideal would be connecting the device directly to a computer via USB or bluetooth and pulling the data / logs off of it directly.

Combined with open data access / reverse engineering this would be very powerful. Basically I want a band where it is impossible for anyone besides me to get access to my data (without physically stealing the band or hacking my computer).

Polar and Suunto were like this in the 90s and 00s.

And they offered fancy features for the time such as VO2max or EPOC.

I wonder if any of their models still work well without apps?
