App Lagging on Opening (iOS)

Hi all,

I’ve been struggling with the iOS app running very slowly, especially when just opened. The UI often takes 20-30s to register screen taps, and then sometimes registers them all at once, creating stacked layers of the same window.

It seems like the app is loading information from the web first, and once that is done, it becomes more responsive. I am noticing this much more since the calendar update, which means I have to use the app rather than the web client.

I am, however, using a relatively old iPhone. iPhone SE 2020 (2nd generation) running iOS 17.7.2. With that said, other more demanding apps run perfectly fine on this same phone.

Is anyone else experiencing lag on iOS?

Sorry to hear about the lag – I’ll send this report along to our engineers so we can look into it!

Same as my iPad.

I thought this was just me and my old iPad, very slow on opening, takes an age to activate ‘load workout’, often multiple taps required, seems pot luck.

I’m having the same issue on iPad 5 mini, iPadOS 17.7.2. I get the spinning wheel for 20 seconds or so. Not just the spinning red circle in the upper right corner of the app (which I do get), but the spinning circle next to the wifi icon in the system tray. No issues on iPhone 13 mini, iOS 18.1.1.

Having same issues on 5th generation iPad running iOS 16.7.10. In addition, when opening the app, TrainNow has been giving me the same workout that I completed the day before. My iPhone is not doing so. This is the first time I’ve ever had any serious issues with TR after many, many years of membership. It’s becoming increasingly frustrating. I really hope the great TR team can get this sorted out for everyone. :blush:

I am still having heaps of issues with app lag in iOS. Recently the app has also been crashing when loading the career page, as well as crashing if the phone is locked during a workout.

I encountered the app lagging on opening again today and, even after having updated to the latest version (2025.12.0 released yesterday), the analyzing screen got stuck after completing both my workouts today… the post-workout survey couldn’t, therefore, appear and that had to be dealt with via the website later.

IOS app is very laggy for me and my GF … things like adding survey responses to completed rides or looking back through the calendar cause unresponsiveness.

Today, with version 2025.13.1.92462 on my ipad, was the first day in a while that the analyzing screen didn’t get stuck after my workout. The whole process through post workout survey worked as I remember it used to!

Thanks for fixing it.
