# Heartwitch 1.0 beta - build 11 coming soon Over the next week you should be getting an update to [Heartwitch](https://heartwitch.app). To get this installed.

1. Accept the invite 2. From the TestFlight app... download the app 3. Run the app from your Apple Watch -  **There is no app for the iPhone**

From there you can start using the app. Here's a video which explains how... Build 11 introduces a few major fixes: - Faster Heart Rate Updates *now heart rates use the newer Workout API which means more updates and less disconnections* - Saved Workouts *now each activity is saved as workout, this means you can look at your heart rate activity later*  Here's an example of a 45-minute elliptical workout I did while playing Mario Kart... If you have any questions or concerns, let me know.
Thanks for trying this app out,
Leo
