## Final claims

| line | claim | verdict | page quote |
|---|---|---|---|
| 2 | The tracker says the field is stalled. | supported | the landscape of genuinely open, stable wrist hardware remains unchanged |
| 3 | The verdict is unchanged since 2026-08-18. | supported | The current state of the art, as of 2026-08-18 |
| 5 | The state of the art is still Bangle.js 2. | supported | The open-firmware wearable ecosystem remains anchored by Bangle.js 2 |
| 6 | Bangle.js 2 is the most mature shipping open watch. | supported | Bangle.js 2 as the most mature shipping device |
| 8 | SensWear and HealthyPi 6 are not yet shipping. | supported | are emerging but are not yet shipping or proven |
| 9 | SensWear and HealthyPi 6 are vendor claims for unshipped dev platforms. | supported | this is a vendor claim for an unshipped dev platform |
| 11 | The gap is a slim pod with PPG, accelerometer, and ambient-light sensor. | supported | no buyable, open, slim wrist pod (PPG, accelerometer, ambient light) |
| 12 | That combination is still custom PCB territory. | supported | a custom PCB or modifying an existing open platform is still required |
| 14 | Pulse-PPG is an open-source AI foundation model for PPG signals. | supported | Pulse-PPG, an open-source foundation model pre-trained on a massive dataset of raw PPG signals |
| 15 | Pulse-PPG is an unverified study from February 2025. | supported | Feb 1 2025 |
