Zwift iOS 15

Has anyone tried Zwift with iOS 15? Can anyone confirm compatibility or if there are any issues?

I’ve done a quick test on my usual zwifting device — 2018 iPad Pro — after downloading and installing iPadOS 15.0, and Zwift worked as it has before, i.e. no problems.
(The update was only made available after my evening group ride, so I didn’t have the chance to ride longer.)

I’ve also just checked Zwift on my iPhone 11 Pro after installing iOS 15.0 and it all seemed fine, too.

Used in workout mode and worked fine on IpadOS 15. Haven’t upgraded phone yet. So Companion was still on 14.8 iOS and communicated fine as well.

In my case so far there’s been a significant performance drop. Zwift was largely smooth on my iPad (all sensors/power were BT smart). The iPad OS 15 update has rendered Zwift incredibly choppy (very low frame rate). Not sure if it’s iPadOS or Zwift (or both).

Performance with my trainer itself seems unaffected - I’m not seeing any significant issues there however. While this is disappointing it’s not the end of the world - though a whole season of this would be hard to stomach.

I’d definitely hold off upgrading if potential visual performance drops would bother you. Will update if things change or improve.


Same on iPad Air4. Need same wrok from Zwift, graphics performance droped.
