## What is Health Data Server?

The watch app requires watchOS 8+

This app was built to get heart rate, calories, and more from your watch into a stream overlay. It does this by sending the data to HDS Cloud (or an IP address/port you specify). A website hosted at hds.dev can be used as a browser source in OBS to show the data.

This app can save workout data to Apple Health

Features:
  - Show your heart rate on stream with just an Apple Watch. No extra heart rate monitors required.
  - The app will only affect your Activity Rings if calories are enabled
  - Heart rate color ranges. Know where your heart rate is at a glance.
  - The overlay app comes with a plethora of customization options. Make your overlay look however you want.
  - The overlay comes with a heart beat animation that matches your real heart rate
  - The overlay can also play sounds to go along with the heart beat animation
  - Even more data for advanced users:
  	- Motion
  	- Every single HKQuantityTypeIdentifier available in HealthKit (so pretty much anything)

Go to https://github.com/Rexios80/hds_overlay for information on how to set up the overlay.

### 5/5 — Works perfectly out-of-the-box

*2023-01-07*

I use this for my stream overlay and it works perfectly. I’ve never had any issues and the developer is super nice

### 1/5 — Doesn’t work without the Apple Watch

*2023-01-06*

This app calls itself a health data server but without an official Apple Watch it seems to be useless

### 5/5 — Love the app

*2022-12-11, version 13.0*

Works like a charm.

### 1/5 — Needs to be updated for 28.0

*2022-10-04, version 13.0*

Doesn’t work with new Obs

### 5/5 — Working Great!

*2022-02-11*

This is working great, and taking our livestream workouts to the next level. And Aaron has been great with communication via email. Perhaps the ability to have sharper, less compress icons when uploaded - but, all in all...great!!

### 1/5 — Doesn’t work

*2022-01-23, version 11.6*

Waste of money

### 5/5 — Definitely the best option to get heart rate on stream.

*2021-07-30, version 11.5*

I used other free apps before and finally decided to give in and get HDS and I’m absolutely glad I did! The last option I used, I had to quickly enter a code and pray it would connect. Now I just open my watch and tap “start workout” and click the visibility flag on streamlabs and boom, instant heart rate for my horror streams. Thank you for HDS!

### 5/5 — Works perfect!

*2021-06-09*

This is exactly what I needed - Simple setup and excellent support to fix my user error.  I use StreamLabs OBS and this is a simple and clean display of my Apple Watch Heart Rate Monitor.

### 5/5 — Nice piece of Software

*2021-04-12*

Nothing Bad to mention here.
Does what it is Supposed to do, no fancy useless functions. 
Great, Awesome work!

### 5/5 — Great App

*2021-04-04, version 8.6*

Easy to set up and does not affect battery drainage. Absolutely worth the price.

## Frequently asked questions about Health Data Server

### What does the Health Data Server app do?

This app captures real-time health data, such as heart rate and calories burned, directly from your Apple Watch. It then sends this data to a cloud service or a specified IP address, allowing it to be displayed in stream overlays for platforms like OBS.

### What are the key features of this app?

Key features include displaying your Apple Watch heart rate directly on stream without extra monitors, enabling calorie tracking that affects Activity Rings, and offering extensive customization for your overlay's appearance. It also includes a heartbeat animation, optional sound effects, and access to a wide range of HealthKit data.

### How is this app monetized?

The application is free to download and use, but it does offer in-app purchases. This model allows users to access core functionality for free while providing options for enhanced features or customization through paid upgrades.

### What are the compatibility requirements for this app?

The watch application requires watchOS 8 or later to function. Users will also need an Apple Watch to collect the health data that the app streams.

### How can I set up the stream overlay with this app?

Information on setting up the overlay can be found on the project's GitHub page at https://github.com/Rexios80/hds_overlay. This resource provides detailed instructions and guidance for integrating the app's data stream into your broadcasting software.

## Version history (last 5 releases)

### 13.1 — 2025-01-26

- Rebuild to fix crash when attempting to input from iPhone
- Fixes full keyboard not showing up on supported watches

### 13.0 — 2022-10-01

- Removed websockets completely
- Removed RTD and REST fallback options. These are now the default.
- Fixed time not updating in AOD
- Improved complications
- Added new workout types: Swim bike run, Transition
- Added new HKQuantityTypeIdentifiers: appleSleepingWristTemperature, runningStrideLength, runningVerticalOscillation, runningGroundContactTime, runningPower, runningSpeed, heartRateRecoveryOneMinute, atrialFibrillationBurden, underwaterDepth, waterTemperature
- Updated watch app display name
- Fixed navigation title display modes
- Fixed a rare issue with the heart animation
- Filter out already selected HKQuantityTypeIdentifiers from the quantity type manager
- Removed unused font file
- Refactoring

### 12.0 — 2022-09-13

- Two new communication methods to mitigate issues with websockets. These methods also allow for the use of HDS without a phone connected: 
- RTD Fallback: The HDS Cloud version of this feature. You will need to enable this in the settings on BOTH the watch and the overlay to use it. 
- REST Fallback: The non-cloud version of this feature. You will need a new desktop app to use this. Please join the Discord server for help with this. 
- Minimum watchOS version is now 8.0 to support always on display. The Series 3 and newer support watchOS 8, and the Series 3 came out 5 years ago so I think it's about time. I will attempt to keep the older version on the App Store, but I'm not sure if that works for watchOS apps. 
- Always on display support (this might require a reinstall to work)
- Complications for quickly launching the app from the watch face
- Switched from URLSessionWebSocketTask to NWConnection for the websocket connection because pings weren’t working anymore with URLSessionWebSocketTask. This was causing the connection to be constantly reinitialized.
- Don’t save workout sessions that lasted less than 60 seconds bbb
- Fixed the text fields so they allow input methods besides scribble 
- Refactored the pedometer speed code. Might have fixed some issues too. 
- The advanced ip entry setting now persists 
- You can now input a port with the keypad 
- Allow backing out of the keypad entry view. This will discard any changes. 
- Removed deprecated dance activity type. This was replaced by cardio dance and social dance in watchOS 7. If you have this selected before updating it will be replaced by the fitness gaming activity type. 
- Added new HKQuantityTypeIdentifiers from watchOS 7.4 and 8.0. These are: appleMoveTime, appleWalkingSteadiness, and numberOfAlcoholicBeverages. Note that you will need a custom server to use these, and they may not behave as expected. 
- Removed leftover unused code from previous refactoring 
- A bunch of other refactoring that shouldn't affect functionality
- Updated dependencies

### 11.6 — 2021-08-10

- Added crashlytics
- Disabled disconnect alert by default

### 11.5 — 2021-06-28

Yeah I broke it sorry. AWS is dumb. This update will make it so it can never break that way again.
