App really lagging like it’s the early 90s
-
I’ve installed the 2026.6.1 update, and like a previous user indicated, it was fine for a few minutes, then lagged just as badly as before. I really want to use my iPad to journal, and I’ve loved this app for years, but it’s practically unusable now. Hope you come out with a new patch soon!

I’m using an iPhone 13 mini, running iOS 26.3.1 and the newly released DayOne 2026.7, but I sadly have to report that the app is still barely usable, regardless of any of the suggestions in this thread.
I downloaded a device monitor app to monitor the CPU load and as soon as I open DayOne, it spikes to 100% CPU load, explaining the lags and crashes.
I really hope for a fix in the next update.

I have been experiencing this issue as well, when opening the mobile app it lags significantly, and is basically unusable at the moment. It even slows down my device when it’s opened. I hope this is resolved soon, I’ve used Day One for years now.

Same here. Latest release is again slow and unreliable when opening and typing, on all iOS devices.
And during this crisis, Day One launches an IA assistant that nobody wants. A bold decision. -
2026.7 just as bad for me on iPad. Typing is just about impossible, plus when I exit the app my iPad is very slow for a minute or two even when I don’t have any other apps open. I presume the app is hogging CPU power for some reason.

Thank you for your patience while we investigated this persistent issue causing typing lag, overheating, and general slowness in Day One for iOS between versions 2026.5 and 2026.7
We had trouble fixing this issue because we were unable to reproduce it at first, so it was difficult to confirm a fix.
We are now in the process of releasing 2026.7.1, which has been tested against affected devices, and we’re confident it will resolve this issue.
Please update to 2026.7.1 as soon as it’s available in the App Store, and let us know if you still experience the same issues after updating.
Many thanks! -
