* Did your running app crash half-way and lose your heart rate?
* Do you just like using the Apple Watch activity app, but still want to get heart rate info onto Strava or Runkeeper?
* In short--do you have heart rate information in Health that you want to see on your run?
I Heart GPX will take a GPX file and check your heart rate data in Health to see if you can attach any of it to that GPX. Then it'll let you save a new copy of that file with the data included.
It should preserve the GPX features below in the exported file; if there's something missing from your export, feel free to send me an example of the input file and I should be able to make a fix.
* Ambient temperature
* Heart rate
iOS Health Integration: This app uses HealthKit to retrieve your heart rate information.
The app will no longer rudely refuse to add heart rate information to runs in some circumstances.
With Family Sharing set up, up to six family members can use this app.
