Hello,
New user here - love the app and interface. I recently started using TrainerDay with my Schwinn IC4, but it crashes (12 X in last 30 min ride). It just quits, I reopen over and over. I have uninstalled, rebooted iPad and then reinstalled but the problem persists. I am using an iPad Pro 11-inch M4 with iOS 18.3.1.
Strange. No one else has issues like this that I have heard of. I will have my developers look at the logs to see if they can find the problem and let you know in the next couple days. I know we have other IC4 users so that should not be the problem.
Some things to try
You could try registering for a new account and just see if it happens on the free version to make sure it’s not something strange with your data.
For now you could use a phone assuming it is issue with M4
We should be able to get this fixed fairly soon if we find the problem. If you purchased from Apple you might want to ask for a refund. It’s cheaper from us and I can’t do much to extend your contract for example if you bought from them. If you bought from us we can figure something out.
Same, crashing in ERG every time there is changes in power
Edit:
I have only seen the problem when there is an interval change in ERG.
No crash in ERG without interval change.
No crash in Slope.
Hmm, so that would make it seem like it is related to your IC4. Let me have my developers investigate our crash logs tomorrow and see if they see it.
I’m another user 
I use a Tacx Neo Bike Plus and iPad Air M1
Oops sorry. Oh very strange ok then two M series users crashing.
I will test my m-series and see if I can replicate it.
Alex,
I was unable to try the suggestions until this afternoon.
russfg is my paid profile
I created russfg01 - as free profile
Maybe related - i noticed when looking at my russfg profile, the
User account info, in the iPad app it says I weight 504.9 lbs (LOL), when I type my actually weight in the field - the app will pop a ridiculous value instead of what I typed. It is set up to access this data from Apple Health and is fine on the website.
Maybe this info will help.
Oh wow… thanks so much. For sure this sounds like it will help.
The only app connected to my account is rungap, also my weight don’t change and its without a comma.
So I don’t think that’s the issue.
Today it also happened in Slope mode, at the end of my workout I did a short push, no change in elevation.
And it happened exactly when the interval ended, aka the same as in ERG mode, where it happens at every interval change.
The funny thing is, when I went back to the app/workout, the time was still running, after the workout should have finished, and the interval was counting down from start again.
I finished the workout (pressed stop), and the workout time only showed the original planned workout time, aka not the extra 5-6 seconds because of the failure.
