You can pair the controllers in the settings you don't need an app. Their VR UX does suck that is true, and horizon worlds is such a collosal failure that I'm surprised they haven't cancelled that entirely yet. But carmack also stated the technical issues numerous times.

No you can't? By their own documentation, you have to use the app: https://www.meta.com/fr-fr/help/quest/967070027432609/

And my quick search on the internet yielded no other mean to pair controllers.
