Slow iOS Companion App

Mobile Apps Home Assistant Companion for Apple
1

The iOS companion app has become painfully slow for me all of a sudden. Takes about 30s to load the app. Backgrounding the app dosnt work anymore, meaning there’s an “ui error” every time I switch back and need to reload.

I’m in the most recent HA and it was an issue already before installing. First few launches after the update it was responsive again but quickly went back to being slow.

Any ideas on what might have caused that or what I can do to debug/improve?

I can’t see anything in logs. Memory is about 60%, CPU around 2%. Perhaps I’ve reached the limitation of my hardware?

Have you gone into the companion app settings > debug > reset frontend cache?

Good idea. Just tried that. No change. App is so bad now it’s unusable for me. So slow to load a page and plenty of non configured entities.

Hmm… if you go to your Settings app > General > iPhone Storage, do you have any free space left? If you’re getting close to maxing out your space, that’ll slow the phone down significantly in-general.

Same experience.
Very slow iOS Companion app on after HA 2026.4 update. 2026.4.1 didnt fix.

I am maintaining 7-8 Home Assistant installations for friends/family, and many of them complain about very slow performance on iOS companion app after 2026.4 update.

Performance in PC browser seems unaffected.

Good idea, but all good ok that front. Regularly delete media on the phone due to auto backup.

I’m actually happy I’m not alone on this one. Hopefully a fix comes along soon enough.

really short update: I’m back home now and the app is behaving fine again. I did nothing. Fast on local network and fast when out and about on 5G. I’ll keep an eye on it the next time I’m abroad…

I’m experiencing the same issue, but it seems to only be an issue on my (wall mounted) iPad. Other devices do not seem to have any observable issues.
When pressing a light button on my dashboard it takes approx. 2sec before the light turns on and the icon changes color. This only happens on 1 view.

Recently upgraded the iPad to IOS 18.7.7
HomeAssistant CORE running 2026.4.1 on a RaspberyPi-4Gb, CPU ~25% / MEM ~ 65%

The problem seems to have started before IOS 18.7.7 / HomeAssistant 2026.4.1

before these upgrades the iPad, and all other devices, responded swiftly. No noteworthy changes have been made to the dashboard the iPad is using.

What I already have done:

  1. cleared front-end cache on the iPad
  2. rebooted the iPad
  3. rebooted HomeAssistant

Any tips on where to look or how to troubleshoot this issue?
