This is awesome! I've been looking for an open source alternative to my Fitbit since Google bought the company.

I'm really just looking for something that can track my health data + sleep and has an api to get the data in a raw form for further analysis.

Earlier quoted context omitted.

Check out the Amazfit Bip (S) watch. Cheap, sleek, waterproof, gorilla glass always-on display, battery lasts a month, does GPS tracking without smartphone connection and you can sync it via Gadgetbridge to keep all your data private without any account/cloud services.

Unfortunately they no longer make them. Or at least I could not find any to be bought.

I'm pretty sure they do; even established stores have started carrying them around here. Check out the website as well; there's a bunch of variations of that watch now.

I have the original Bip and am very satisfied with the hardware (lasts forever, looks pretty good) and somewhat satisfied with the software (good selection of watch faces, it's gadgetbridge compatible, but activity mode is a tad bit too easy to enter and too hard to exit)

I would totally buy it if I could order it locally in Europe. When I ordered a PinePhone from Hong Kong, it was just too much of a hassle for my liking. Waiting for an indefinite amount of time until it gets shipped and then deal with customs. I wonder how many customers there are per country. Would it make sense to have local distributors around the world? Or maybe at least one per continent?

Pine64 has announced that they will open online retail stores in certain regions, including Europe and North America, this year:

These new stores will offer a higher standard of customer service, but the products will also be priced higher. The original community Pine Store will remain available in its current form.

This is really cool. $25 is quite impressive too. A GPS would be killer though.

But doesn't quite scratch the itch that I've got for a higher level open source wearable or tablet (think IP67 Raspberry Pi tablet or watch) The key is that like this watch, the hardware is done and "consumer" ready.

you can modify the behavior of the crown button to disable this, if i recall correctly. i think i just deactivated it - after one too many accidental presses.

Promising specs! I'd rather have multi-day battery life than fancy graphics, maybe even an e-ink display.

I dunno. I get two days out of my Apple SE. Doesn’t seem too much of a bore charging it.

i still forget to charge my pebble time steel sometimes cos it lasts long enough for that to happen. I don't need to pack a charger for it on short trips, weekends, etc.

I prefer it that way. would not want to charge yet another device every day or every other day.

Me too. It says "All-week 180 mAh battery" which I'm not sure what it means but I doubt a 180 mAh lasts an entire week.

It's a milliamp-hour.

The processor draws about 220uA [1]

so you have about 818 hours (=34 days) of CPU time, but you need to take display current out of that budget too, and an easy source for that probably exists, but I can't find easily.

Same here. Not only does it save battery life; it ensures the display is always on and looks way better.

The Pebble Time had a Sharp Memory LCD, I'm not sure what the Amazfit Bip uses.

It's baffling that there are so few electronics in general that use E-Paper/translective displays. Does anyone know?

The PinePhone is a special beast that had or still has some supply issues AFAIK (also with the higher value customs issues are more likely).

I personally had no issues ordering stuff from Pine64, albeit it did take long.
