Data and Accuracy is NOT accurate
I try to ride exclusively outdoors but certain times it’s just not possible. I have several frustrations with the app but these 3 alone make it not worth having.
Performance accuracy: I have 2 bikes I connect and both have skewed data when doing rides with the app. The accuracy of output watts and hills do my compare to accurate effort. Outdoors with my Ralley pedals and Garmin 1030, I never drop below 17mph on anything under a 5% incline. In the app a 3% incline seems to translate to a 8-9% incline. It’s totally inaccurate and frustrating.
Multiple rides: I’m not a fan of ZWIFT but at least you can just ride and accumulate distance non-stop. Most Tacx rides are only 20 miles long and unless they are in a challenge there’s no way to string them together so if you plan to do a 60-80 mile ride you’ll have to log 4 seperate rides. The results are not accurate because it’s looking at multiple rides vs 1 sustained effort.
Garmin Points: Even if you use your $1000+ TacX trainer and ride using Zwift or Rouvy, Garmin doesn’t give you credit for the ride or towards badges. You have to use their 1990s data integrated TacX app as well.
I have Garmin watches, bike computers, bike lights, bike radars and Ralley pedals and I’m about to get rid of it all because Garmin won’t upgrade the TacX app to make it usable.

Small display
Active workout display arrangement is now smaller- can’t see it without eyeglasses
Vibe coded slop
This app has so many bugs I don’t even know where to begin. It use to be serviceable and now it’s just a nightmare.
Bluetooth issues.
Where’s the timer for power workout. Also we really need to ability to set favourite workouts. To get to vo2 workout takes screens and screen of “load more”.
Good Power Control
Preferred previous, larger metrics in Power Workout UI. Would be nice if there was ability to preprogram specific power settings to jump to with simple Next / Previous buttons: e.g. 50% FTP / specific watts, 80% FTP / specific watts, etc.
