Nitpick regarding apps: https://flathub.org/en/apps/collection/mobile/1 is the better link IMHO, even if not all apps in it do actually perform great on mobile [0], and some apps that work well on Mobile are not part of the collection due to lacking some bits in app metadata [1]. Help with sorting this out is very much welcome :-)
