It looks like Pinetime lets you customize the watch face with Rust, but is it touchscreen? Am I right in seeing that it only runs the update logic once every minute?
The rust part is kinda not true... You can only really use wasp os and infinitime, and neither of them support rust watchfaces. And yes, it is in fact touchscreen.

Section 1, step 2 states "update: To update the Watch Face with the current date and time. This is called every minute by the PineTime Firmware to refresh our Watch Face."
Good to know that it's touch screen. I would love if I could push a button on this watch and run a POST request to my server. Do you happen to know of that's possible?
Yeah, I was imagining that it was connected to my phone, but I'm not sure how to setup my phone such that it responds to messages like that - I've never tried sending my phone bluetooth messages and I don't know if that would be possible (to go watch to phone via BT and phone to self-hosted server via mobile network). Can I have an app always listening for messages over BT? Hopefully I don't need a PiZero W in my pocket: watch to Pi via BT as a relay, Pi to phone via Wifi hotspot, and phone to self-hosted server via mobile network. Sounds like a lot of work, lol. I'll think about applications for it. They'd have to be pretty awesome.
