I purchased a treadmill that has iFit so I downloaded this app so I would get "credit" for my long walks and hikes. This app is full of bugs that never get fixed. The app starts and says it is looking for GPS, but if it doesnt immediately start, that message is there 20 minutes later and nothing is recorded. I have to close the app and restart it, sometimes 4 or five times. If it doesnt start by 8 or 10 times, I have to delete the app and reload it on my 6+, which always works. I can open up a navigation or walking app and it works immediately when the iFit app doesnt, so I know it is the iFit app. The app sometimes stops in the middle of a hike and says "unfinished workout" save or resume. I click resume and it restarts but I loose everything from the time the message initially pops up. When I finish my hike and try to end the hike, sometimes the screen just freezes and does nothing. I close the app and reopen it and then close the last hike. If I open the history, several hikes show as not uploaded and I cant figure out how to manually initiate an upload to the iFit web site. It is very sad that iFit released this and fails to support it at all. If my treadmill didnt have iFit software on it, this app would have been deleted a year ago. If you dont have iFit, dont waste your time on this worthless unreliable and unsupported software.
