### 1/5 — App won’t open

*2023-01-22*

I wanted this app to track my heart rate during exercise. I purchased it in the App Store and instead of it downloading, it just says “purchased “ blacked out. I went to my settings to see if it’s in my list of apps and it is nowhere to be found since it seems that it has not downloaded at all. Please fix!!

### 1/5 — Bad

*2021-05-20*

This app did not work at all

**Developer response:** Sorry to hear!  I'm happy to assist if you can provide more details to the support email address.  Until then, please ensure you have granted HealthKit permissions to the app.

### 5/5 — Works

*2021-06-07*

This app is much much more useful than the one you have to pay for (beat watcher). I wish this app could collect cadence data, too, for outdoor running. But aside from that you can run this app while running and it warns you when your heart rate is above the desired limit. You can run this app concurrently with music app, too.

**Developer response:** Thank you for the review!  I’m interested to hear more regarding your cadence feature request.  If you would like to provide more details please email me at support@basebuilder.app. Thanks for using Base Builder!
