heartbeatz Connect 4+

I downloaded this app because I added the Runn treadmill sensor to my treadmill. Since Apple workout won’t read the data from Runn, I used this app on my Apple Watch to record my workout. It reads all the data correctly from the Runn and uses my heart rate from the Watch. The problem? After the workout is complete, it records double the miles I actually ran in Apple Fitness. North Pole support says it’s a bug that will be fixed in the next version. Been waiting since mid February. If they can fix this bug, I’ll give it 5 stars. Does everything I want…except the double counting.
I know the Runn is outputting correct data because I can use it with the Kinomap app and it does not count double mileage.

I use this watch app almost every day and previously rated it five stars. I'm now rating it two stars. The latest app update continues to function fine, but the first watch screen no longer shows the information most needed by runners on the treadmill. Specifically, the first screen now shows the time, BPM, active cal, and total cal. The second screen shows the total mi, mph, pace, and percentage incline. Please make sure that, when selecting the Indoor Run workout option, the screens are either configurable via the phone app or ensure that the first screen shows total time, total mileage, mph, and optionally BPM. The other items can be moved to later screens. Also, lower priority, please make the two buttons pressed simultaneously function as pause just as the Apple Workout watch app does.

….. without an issue. Does what it says. I use it as my HRM while cycling.
