Connected Health
Your devices can do more of the recording.
Connect Vayru to Apple Health and supported information from compatible apps and devices can contribute to your focused fluid and health diary—with your permission.
💧
Your water bottle already knows how much you drink.
When a compatible bottle shares hydration data through Apple Health, Vayru can use supported information to help keep your fluid intake records up to date.
- Less manual entry
- Apple Health remains optional
