I bought a sealed device, with the intention of doing development but have not yet done anything like that

I installed GadgetBridge on my Android phone, paired it with the watch, uploaded the latest PineTime firmware, all without looking at code or opening it up or anything

It works perfectly fine as a basic watch with step counter and heart-rate monitor (although, I am not sure how accurate these features are)

If you can browse the web, download files, and find that file again when using a different app, then I think you’ll be fine

I have a pinetime. Like basically every other Pine64 project (except the pinebuds, which are good, not great), it’s lousy as a daily-use device and only of interest if you want to hack on an embedded device.

Check https://banglejs.com, the hw of the banglejs2 is exactly like an amazfit bip (which is great) but the firmware is open and programmable in js. Fyi the screen is transflective, which makes smartwatchces perfectly readable under sunlight without turning it on, like e-paper. It’s just lower in resolution bit it will last 30days without charging it.
