Welltory: Heart Rate Monitor is an Apple Watch app that works with the Health app to provide comprehensive data about your heart rate and stress levels. It gives you daily health metrics and insights about your overall health by tracking over 140 data sources. You can also monitor your progress over time and see how effective your exercise regimen is. The app is compatible with other devices like Garmin, Fitbit, and Oura.

Welltory also includes a breathing app that helps you calm your mind and relieve stress. It offers daily life hacks to improve your health and encourages you to take time for self-care. While the app has a subscription-based service for additional information, it still provides a lot of valuable information for free and doesn’t constantly push you to upgrade.
