Hello --- I made this! Thank you for the kind words.

I have, BTW, just received a $6.50 watch with touchscreen, microphone and speaker, much better build quality, BT 3, 4.2 and 5, plus the traditional fake heart rate sensor and a bigger battery with an actual label on it. It's powered by a YC1133 which contains an ARM Cortex M0 with 56kB RAM and 4MB flash. This would be an awesome device for hacking if there was any information about it whatsoever.

Weirdly, it runs a more complex version of what's clearly the same software stack as the LT716!

Is anyone working on an OpenWhoop? The algorithms/scoring/etc seem ripe for a collaborative open project. A $100+ version of this thats broadly hackable would be cool

I've been looking for one as the Whoop's data sync with Apple Health is bad.

There is an app on iOS called "athlytic" that is basically this.

Why not a lillygo T-Watch? It's a bit more expensive, but it's a solid one with good specs and an esp32 https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library

oh neat. It's a different sort of fun - but I just got one of these to play with it with the kidlet.

My friend wrote Micropython so I’ve passed this along to him! Very cool.
