It is open sourcing the repebble app here: https://repebble.com/app

Looking through the code, most calls go to repebble.com, rebble.com and rebble.io domains. Most of it seems to be for login, firmware downloads, settings synchronization, weather forecasts and language packs.

There are also some calls to memfault.com for crash analytics.

Most of it seems pretty innocent. If you don’t like this app you can also use Gadgetbridge as an alternative.

A lot of this info has been restricted in newer versions of Android, so you can only get this info if you have root access.

That sucks. I was considering one of their devices instead of a Google Pixel, mainly due to the form factor. I guess not anymore.
