A ring, not a gadget
Most wearables ask you to look at a screen. Beyouda does the opposite. It disappears on your finger, quietly reads what your body is doing day and night, and gives you one clear thing to do about it.

What it measures
Sleep stages (deep, light and REM), resting heart rate, heart rate variability, blood oxygen, skin temperature, stress and readiness, steps, distance, calories, and your cycle. More than fifty signals in all, gathered while you get on with your life.
What makes it different
2.4 mm thin, titanium, six finishes. Most people never guess it is a tracker.
A full charge takes sixty minutes. Once a week, not once a night.
The app is free for life on iOS and Android, in every language.
Cycle tracking is not bolted on. Temperature trends and cycle phases sit right at the centre of how the app reads your week.

Wear it, then forget it
Water resistant to 100 m, so it stays on in the shower, the pool and the sea. No screen, no lights, no buzzing. The only moment it asks for your attention is when you open the app yourself.
Not sure about your size? Our on screen size tool reads it in about ten seconds from a ring you already own.
