Building a screenless wearable, one thing hits you fast: the app isn't a companion — it's the device.

We built it on Flutter — open source, like the firmware and hardware. From PCB to pixel, no closed layer.

The app (iOS + Android) shows HR, HRV, SpO2, sleep, activity, temp — plus Recovery, Illness Detection, Training Load, Body Battery.

Announcing the HealthyLink Edge AI Accelerator for HealthyPi 6.

The STM32N6's Neural-ART NPU delivers 155x faster inference — beat classification drops from 233ms to <1.5ms. At 600 GOPS and just 0.5W, it boots in <100ms and runs 20+ hours on battery, running on Zephyr @zephyr

Bring your own TFLite/ONNX models via ST Edge AI.

HealthyPi Move Gets a Makeover

It's been over a month since our last update, but there's a good reason for the delay. We've been working hard to finalize the look and feel of the HealthyPi Move enclosure, and we're excited to share the results with you. We ended up changing almost every part of the design, from the display to the enclosure, and we think you'll love it. We've even got a big surprise for our backers in this update!
