alt Hacker NewsTermux is one of the best apps ever made for Android power users. It literally replaces so much stuff, if you don't care about GUI. No need for SSH app - it has ssh. No need for file sync app - there is rsync. No need for notetaking app, there is your $EDITOR you like. All 100% free. It's amazing.
+1. Termux absolutely rules and makes the dream of a cyberdeck actually viable. I use it at least once a week for various homelab stuff.
