I already have a Pixel Watch that I actually like quite a lot and enjoy the information summaries available via Fitbit. I guess what I'm asking for are open source alternatives to Fitbit that can collate the data and present it back to me in a beautiful fashion rather than new hardware?
My watch is very much an extension of my phone experience rather than an individual thing like fitness or sleep tracking. Being able to read notifications, answer phone calls and control my music are imperative to my user experience and the sleep and fitness tracking for me are just bonuses.
