Not much. It just has its own button on the home screen (iOS) and behaves (mostly) like a native app. A browser bookmark would work as well. Miniflux is designed to work well on a small screen with touch input. So the fact that, unlike some other options, it doesn't have a native app is not too much of a limitation.
