App Links

Web app

• For use as a browser source
• If you use HDS Cloud, all you will need is this and the watch app
• Heart rate is free forever with HDS Cloud (assuming you bought the watch app)

Apple Watch app

• THE APP STORE VERSION OF THE WATCHOS APP REQUIRES WATCHOS 8+. The App Store will let you purchase it even if your watch can't run watchOS 8+, so make sure before buying.
• If your watch cannot run watchOS 8+, join this TestFlight group to get HDS Legacy

Android watch app

• The Wear OS app currently works on Wear OS 2, but can only send heart rate. If Wear OS 3 ever starts behaving, I will work on an update to send calories, step count, speed, and distance. Please note that this update will ONLY support Wear OS 3.

Windows/macOS/linux executables

• For local data routing (no cloud)

Required Reading

HDS Cloud IDs

An HDS Cloud ID is the identifier used by the watch app to send data to a specific instance of the HDS web app

Notes:

• The first time you open the HDS web app in a new browser, it will generate a new HDS Cloud ID that is unique to that browser
• HDS Cloud IDs will not change within a browser unless you clear the web page data. This includes applications with embedded web browsers such as OBS, Streamlabs, etc.
• Every instance of the HDS web app has its own HDS Cloud ID
• HDS Cloud IDs cannot be shared between instances
• You must input the HDS Cloud IDs of all the instances you wish to send data to into the watch app

Setup

Set up with HDS Cloud

1. Download the watch app for your device
2. Add hds.dev as a browser source in OBS
3. Input the HDS Cloud ID from the browser source into the overlay ids section on the watch
4. (optional) Hold alt (Windows) or opt (macOS) and drag the edges of the browser source to crop it
5. Click the start button on the watch
6. It should just work™
7. To edit the overlay configuration right click on the browser source in the sources list and click Interact

Set up the old fashioned way

Heart rate is free forever with HDS Cloud. Unless you need more data than just heart rate and don't want to pay the subscription or do not have internet access this section is not for you.

• See the hds_desktop repo

Useful things

• You can import a config with a url parameter. This is useful if you want to use something like the Streamlabs mobile app in which you cannot interact with the web page.
  1. Use hds.dev to create the overlay configuration you want
  2. Click the export button in the top right to copy the configuration to your clipboard
  3. Use https://www.urlencoder.org to encode the config that you just copied
  4. Create a url that looks like this: https://hds.dev/#/overlay?config=Encoded config
  5. Use that url as a browser source in your app of choice
