Yoi: Rest & Recovery

Yoi is a quiet rest-guidance app for endurance athletes who find it hard to stop. It reads resting heart rate, heart rate variability (HRV), sleep, and workout history from HealthKit on this device, then shows a simple daily rest guideline. This is not an app for adding more training. It is not for comparing yourself with others. Some days have margin. Some days call for restraint. Some days are for the courage to rest. Yoi gives you a small signal to help you keep going for the long term. Features: Daily rest guidance from HealthKit records Support for resting heart rate, HRV, sleep, and workout history No account required No server required No external HealthKit data transmission Quiet moon-based Widget HealthKit data stays on this device. It is not sent to external servers, used for advertising, used for tracking, or shared with third parties. This app is not a medical device. It is not intended for medical diagnosis, treatment, disease prevention, or medical advice. If you have symptoms or health concerns, consult a qualified professional.
