Favorite Android Apps
Client for Mastodon, Pleroma or any other compatible service. Much lighter than its main competitor (though not exactly light as such).
Outliner using Org Mode as an interchange format. Hands-down one of the most useful Android apps out there. Very friendly, too. It helps to know a few things about the underlying file format, for example how to set a notebook title and what drawers are.
Mobile browser with many options, that looks a lot like Midori except it's noticeably smaller and doesn't track you. Has a Material Design user interface that can be optimized for use with thumbs.
Just "Editor" for friends, it's an app as tiny as it is useful, with many features otherwise found in others ten times larger.
Z-Machine interpreter with a chat-like UI. Elegant and lightweight. Has its own game store and can also import downloaded story files.
Orthodox file manager with excellent connectivity features. Lacks an internal text editor, so you'll have to install one for F4 to work.
Modern client for the Gopher protocol. Supports a bunch of unofficial extensions. You'll want a big screen for ASCII art.
Call it a calculator that uses math notation, with all the bells and whistles. Call it a math cheatsheet that also does the math for you. Or maybe a way to write papers where the function graphs are actually live. It took me a couple of tries to figure it out, but then it became quick and easy. Also fun.
Mobile client for the eponymous cloud software. Incredibly useful. Does way more than just sync.
