I used to think having Emacs on a phone was a bit much..but recently I’ve just started using Emacs and Org mode for nearly everything.. There’s not a great selection of apps on Android for accessing Org files, the best solution to me was to just get Emacs with it’s fully fledged Org on mobile. The newish GUI Android Emacs app is a bit strange and I swiftly uninstalled it. The Termux terminal version however, works much better.
