GymTrakr 4+

The only way I can get it to connect consistently to my True PS300 is to hit the Bluetooth button on the treadmill and wait for the four digit number, then open the app. Opening the app before hitting the treadmill button results in never connecting.

App does not sync with Strava. You have to manually save the .fit file and then use the web version of Strava to upload the file.

If you do a heart rate controlled workout on the True, the .fit file will include the warmup time and miles but not the speed or heart rate data. The result is you run at 60 mph for the warm up portion after you upload to Strava. Heart rate is also a straight linear line from beginning until you begin the HRC portion.

The pace shown according to Strava verbs by about 30 seconds per mile at a constant speed. The average shown is correct but the variation per second is not consistent even when you are running at a constant speed.

Elevation data doesn’t show. I am not sure if this is the app or the treadmill though.

When I users Zwift with the treadmill, that app connected immediately and the data doesn’t have the variability and records the whole run including elevation.

About all this app is good for is saving your time and miles. That is after you get it to connect.

I use GymTrakr often as the treadmills at my gym only connects with Apple watches and not my Garmin due to it’s ANT+ only communication. But it’s no problem with GymTrakr as it uses Apple compatible signal.
However, elevation data changes from feet to miles after a certain point, so you lose the precise footage data. Not good. User should be able to change this.
You can save workout data but not the elevation gain, this should also be fixed.
So in the meantime, I screenshot the data on the Iphone before quitting and saving so I can manually input data in Garmin and/or Strava.

My gym recommended using this app with their cardio equipment and most of the time it just says “No machines nearby” even when I hit the Bluetooth button on the machines to pair. Yesterday it popped up 3 nearby machines but showed no data when I paired to any of them. Then I restarted the app and it showed nothing nearby. I got it to work one time with a stationary bike and the data was great to correct some of my data recorded in my garmin app that was incorrect like distance. It would be a better app if it worked 100% of the time and also exported to other apps.
