Wearables are the one area where I'm really not happy with the efficiency of software.
They don't really do anything that couldn't be done on early 2000s handhelds, why don't we have any kind of app-capable micro RTOS with an accompanying app store on Android for this stuff? An ESP32 and a microSD seems to be all any of it really needs.
Pebble(Like Garmin which seems to be the modern equivalent, that I used to use before getting a Galaxy Watch) only had a tiny amount of flash storage and couldn't do maps or voice recording very well.
The also used e-ink on one, which was probably slow, and it didn't have a touchscreen.
It seems like they were explicitly trying to keep the features fairly simple, but they could probably do a lot more with similar battery life.
