Health Data Server is a lifestyle app designed for iPhone users who want to display their heart rate, calories, and other health data from their Apple Watch on a stream overlay. Developed by Aaron DeLory, this full version app allows users to send their health data to HDS Cloud or a specified IP address/port. By using a browser source in OBS, users can easily showcase their data on a website hosted at hds.dev.

One of the standout features of Health Data Server is its ability to save workout data to Apple Health. This ensures that users can track their progress and analyze their performance over time. The app seamlessly integrates with Apple Health, making it a convenient addition to any fitness routine.

With Health Data Server, there is no need for additional heart rate monitors as the app utilizes the heart rate data from the Apple Watch. The app also offers a range of customization options for the stream overlay, allowing users to tailor the appearance to their preferences. Additionally, the overlay includes a heart beat animation that matches the user's real heart rate, adding a dynamic visual element to their stream.

For advanced users, Health Data Server provides even more data options, including motion tracking and access to every single HKQuantityTypeIdentifier available in HealthKit. This extensive range of data allows users to delve deeper into their health and fitness metrics.
