Keep in mind that non-hardenized containers only protect you from bugs, they don’t protect you from sophisticated malware. If you suspect the software you are trying to run might be a virus, don’t run it, or run it in a virtual machine.

I would recommend using containers only if you absolutely understand how to make them secure AND you have no reason to suspect the software you are running might contain nefarious code. In any other case use a virtual machine.

1099$, seriously? 😅

Be warned though, the hearth rate monitor doesn’t work particularly well. And there is no sleep tracking afaik.

If you’d prefer something more reliable (but less open), GadgetBridge is an Android app to interface with commercial smart watches through reverse-engineered protocols.
