00:00:00.000 --> 00:00:02.595
<v Wren>So open health wearables are finally here?

00:00:02.755 --> 00:00:05.725
<v Ash>Actually, the tracker says the field is stalled.

00:00:05.885 --> 00:00:10.205
<v Ash>The verdict is unchanged since 2026-08-18.

00:00:10.365 --> 00:00:11.735
<v Wren>Wait—nothing new?

00:00:11.895 --> 00:00:15.265
<v Ash>Right. The state of the art is still Bangle.js 2.

00:00:15.425 --> 00:00:18.120
<v Ash>It's the most mature shipping open watch.

00:00:18.280 --> 00:00:19.975
<v Wren>What about newer platforms?

00:00:20.135 --> 00:00:23.880
<v Ash>Like SensWear or HealthyPi 6? They're not yet shipping.

00:00:24.040 --> 00:00:27.435
<v Ash>They are vendor claims for unshipped dev platforms.

00:00:27.595 --> 00:00:28.990
<v Wren>So the gap is still...

00:00:29.150 --> 00:00:34.045
<v Ash>A slim pod with PPG, accelerometer, and ambient-light sensor.

00:00:34.205 --> 00:00:37.525
<v Ash>That's custom PCB territory, even now.

00:00:37.685 --> 00:00:39.230
<v Wren>One promising thing?

00:00:39.390 --> 00:00:45.060
<v Ash>The Pulse-PPG foundation model, an open-source AI for PPG signals.

00:00:45.220 --> 00:00:49.665
<v Ash>But it's an unverified study from February 2025.
