I am exactly the same way, I hate cluttering my phone with apps. I use the potter slots login directly through my mobile browser and it works like a charm. The site is built for mobile-first play, so you get all the slots and the live play vertical without needing to download anything. I play live blackjack on my lunch breaks and it never lags. The layout stays clean and you can access the Rewards Center and the cashier just as easily as on a desktop. It is probably one of the smoothest browser-based experiences I have had in a while.
