Loved it. Needs work!!

Been using this app for years so I don’t want to change apps now but so many problems. Switched from blue tooth chest strap due to HRM monitoring issues to and arm band for same reason and ultimately to Apple Watch. Just plain janky now. I have to uninstall and reinstall the app regularly on the watch to make it function and connect with the app on the phone. I kept getting developer updates and they kept saying an independent app for Watch is coming but still hasn’t. Now it’s so janky I have to uninstall the app and reinstall on my phone pretty regularly and that’s so annoying bc it takes a while for all the data to sync back. They really need to figure this out bc I love this app, but using it is getting ridiculously inconvenient and constantly stops up my workouts bc I’m messing with it trying to make it work. This was true on both the series 3 and now series 4 Apple Watch.
Please improve app stability and make the independent Apple Watch app ASAP!!!


Great for Spinning

I have used this app for the past 3 years in conjunction with my heart monitor. I have found the calorie count and other statistics offered in this app to be quite useful. I especially enjoy the ability to review past performances and compare them to my current results. The ability to edit the data (filling in missing information) allows me to have complete historical results. As an example, some of the spin cycles I use do not transmit the mileage. The ability to enter the mileage after the fact enables me to have continuity in my results. I would highly recommend this app for anyone seeking an easy and accurate method to track your exercise results.


Stopped working

I have been using this app for a couple of years with my scosche heart rate monitor and originally liked it so much I paid for extra features. I just got a new scosche heart rate monitor and could not get it to work with this app. I deleted my old one and now this app will not pair with the new or the old one. Customer service has been quick and nice but they cannot figure out what is wrong or help. I downloaded another app and it pairs with the heart rate monitor just fine. I have followed the trouble shooting instructions several times and this app just will not find the heart rate monitor, old or new. I went from loving this app to not being able to use it at all. When I first got this app it was very easy to use and pairing took just a moment.
