I have a Ticwatch S2 (tunny) which was not officially supported but I managed to get it running and it was cool but not well integrated. The maps didn’t work, most apps were only a little functional, and syncing with a phone was not stable.

Those all sound like bad things and for a finished product they would be, but solving problems is fun if you have the right mindset. I love the idea of using a real qt based interface rather than running modified android or similar. It was very fun to play around with but ended up being less than perfectly suited for me. I want them to succeed though, so I hope they make more progress and get some better results.
