Yuelu - HRV & Health Tracker
Sleep, Recovery & Body Age
Free · Designed for iPad. Not verified for macOS.
Turn Apple Watch and Apple Health data into a calm daily view of HRV, sleep, recovery, body energy, and workouts, so you can train and rest at your pace.
Yuelu helps you understand your body through Apple Watch and Apple Health data you authorize. See HRV, sleep, recovery, body energy, biological age, workouts and daily health trends in one calm, privacy-first app.
Built for iPhone and Apple Watch
Yuelu brings together health signals that are usually scattered across different screens and turns them into simple, readable views for everyday reflection.
Key features:
- HRV and heart rate trends
Follow heart rate, resting heart rate and HRV patterns over time. Use your personal baseline to notice recovery changes and daily rhythm shifts.
- Sleep and recovery
Review sleep duration, sleep stages, recovery context and nap records. Yuelu can write validated nap sleep records to Apple Health only after your confirmation.
- Body energy and readiness
Check a daily body energy score and morning readiness view to understand whether your body may be ready for activity, rest or a lighter day.
- Biological age view
Explore a wellness-oriented biological age view based on multiple authorized health signals, designed for long-term trend awareness rather than one-day judgment.
- Workout support on Apple Watch
Use the watchOS app during workouts to view live metrics. In workout scenarios, Yuelu can also broadcast local heart rate data to compatible nearby devices.
- Watch face complications
Keep important metrics closer with Apple Watch face complications, including quick access to HRV and other daily health indicators.
- Health overview on iPhone
Use the iPhone app to review health, training and settings in a clear dashboard built for repeat daily use.
Privacy-first by design
Yuelu does not require an account. Health analysis is processed on device, and this version does not upload your health data to Yuelu servers. You stay in control of Apple Health permissions.
Important note
Yuelu is a wellness and fitness reference app. It is not a medical device and does not provide medical diagnosis, treatment or prevention advice. For health concerns, please consult a qualified medical professional.
