Too bad it requires Bluetooth classic or else we could port this to Pebble!

Here's my answer (as the founder of Pebble - both eras!) on this. We're a small company this time (standing on the shoulders of giants by using open source PebbleOS - thank you google!).
We are excited to make new devices, but wary about over-promising. We'd rather under-promise and over-deliver. So far, we have only received a few requests for warranty support for our first new watch (Pebble 2 Duo) and we have provided support for everyone who has asked.
Generally most sleep tracking products use actigraphy (measurements of your movement) to track sleep. Pebble partnered with researchers at Stanford back in the day to produce an algorithm for our operating system, which worked quite well and is now open source!
You can read the code and see how the sleep tracking algorithm works here - https://github.com/coredevices/PebbleOS/blob/main/src%2Ffw%2...
Unfortunately no - it basically had zero usage
It has a built in weather app and hundreds of watchfaces that show weather as well.
Sleep tracking works well on all Pebbles!
Would make it thicker, I wanted it to be very thin.
sharp, same display that's in Garmin MIP watches (like Forerunner 255) but tbh looks much better in Round 2!
No plans to offer more SKUs, sorry. Already have enough to manage.
still works fine with iOS, will work even better in EU next year when Apple is forced to comply with the DMA.
Still doing our water resistance testing on Round 2, but that is the target (30m water resistance)!
> Screws
Nope! No screws on this one.
> Is that a matter of adapting the watchfaces to the bigger screen?
Yes, exactly.
Proud of this one! Feel free to ask any questions you might have.

There are several different options you can pick from between 50MB and 600MB.
It has a hard cutoff built into the firmware at two minutes so after that point the recording stops and the ring turns off until the next button press.
This isn't a question I understand, but I appreciate you writing it. At the end of the day it's up to you - if you think this is useful, please use it. If you don't want to use it because of the 4.7 grams of e-waste, I do get it.
All consumer tech is intentionally disposable. That's life. Especially for tiny smart rings that are water resistant. It's a ring, it's going to get banged up, you'll lose it or smash it. It's new tech - there will always be a new version, etc.
Better to have loved and lost than to have never loved at all.
You could write software to do that if you wanted to
The firmware is not open source. I licensed it from a friend of mine.
You can definitely assign different actions to button presses, that's handled by the phone side
1. smallest size is 6
2. yes! You can send your recordings to any webhook.
3. yes! can even shower with it on
The app is 100% open source so you could add that feature if you wanted to. We'd love a PR for that!
Technically possible and it's a feature that will be supported
Yes, that's in the works!
it happens occasionally like when you're leaning against a table at the exact right angle. but I don't think I've noticed it more than a few times.
Should be possible! Battery would last for decades in this mode.
We thought about this of course: the ring is limited to 2-minute recordings, then button presses are ignored until the next button press
If you look at other rechargeable smart rings they're in the $250 to $300 range, plus a $10/month subscription. We didn't want to do that for a new product like this.
It can work exactly like that, if you have a Pebble. But it works standalone as well.
