The reasons that show up again and again in our reviews
Resting heart rate, HRV and sleep debt combine into one number each morning: train hard, train easy, or rest.
Validated against polysomnography within 8% on deep sleep — not a guess from movement alone.
A 200 mAh cell and a monochrome always-on display. Charge it the same day you change your bedsheets.
Every metric is free in the app. We sell hardware, not a monthly bill.
Same build quality across the range — only the details change

Accurate and comfortable. I wish the app exported to CSV, but the basics are all there.
Dispatched same day on orders before 3 pm
No. Every feature in the app is included forever, including the recovery score and sleep staging.
