We were able to connect via Bluetooth to our Spirit XT285 treadmill with no issues. However, the incline levels don’t change according to your incline level or at all for that matter. The only reading that appears to be accurate is mph, time and heart rate. You can not physically change any treadmill settings from the app so if that is something that you are looking for…maybe this app isn’t for you. If this app functioned and at least accurately depicted the information on my treadmill, I would probably give it a 5 star rating. Hopefully this issue is being addressed because if not, it is pretty useless for tracking and sharing info with Apple Health App therefore my wife and I will be deleting in the near future.

My biggest complaint about both apps by this developer to track workouts is that you have to download and end the workout or snap a picture or figure out how to get the data to sync to Apple Health before your workout session ends because as soon as the program finishes and the data on the display disappears you can’t retrieve it. There’s no going back. It’s very frustrating. I would also like to see steps on the display screen on the app since steps are tracked in many fitness trackers, including Apple Health.

Actually useless app. The watch app is somehow even worse. On a stationary bike, I get blank metrics except for time, which syncs up with the bike display and is the only thing that works. Other metrics will periodically flash for a second, maybe three times on an hour long ride.Importantly, the WATCH APP will only record heartrate for few minutes before quitting, AND heartrate only displays on the app when the watch screen is ON. No persistence, and after a few minutes it’ll quit. Hilariously bad app.Treadmill, same thing. Useless watch app. I want heartrate data, so I literally just take a picture of the display and upload to Strava manually.Spirit team - either get a new team on the app and invest in it, or just remove it. It’s an embarrassing product for you to put out into the world. The treadmill is fine but I’m always going to avoid Spirit. I hope whoever decided this app was ready to release is in charge of nothing else. Honestly, I’m hardly ever this vitriolic, and rarely write reviews, but this app, I just don’t understand how.

I’ve owned two Spirit treadmills but the latest model with digital interface is horrible fail. It updates in the middle of workouts and doesn’t sink data to the app as promised. When I downloaded app, it must be invisible because no matter how much looking I do, the only way to find it is to ask my phone where it is!! Doesn’t matter anyway because none of my workout stats are there. Based on the reviews, I’d say none of the issues with the product or App have been resolved since its original design. I’m terribly disappointed.
