Router application accessibility.

Hello all. I am in the market for a new router and am looking for one with an accessible companion app that will let me tweak advanced settings from within the app. Does anyone have any recommendations? I am looking in to Asus and Linksys but I am not ruling out Netgear. I do not want to buy an Eero router unless that is the most accessible option. Ubiquiti routers do not have certain things that I need. I appreciate any help.
