Android apps that I think are great
A list of android apps I can recommend.
OLauncher
If you want a simple and elegant android launcher, Olauncher is for you. It removes all icons from the screen and allows you to add just 5 applications to the main screen. These apps are displayed as text - no icons. You can swipe up to see the full list of applications. Also supports swipe customization - for example, you can set left swipe to open contacts, and right to launch the camera.
Markor
Markor is a markdown editor with a lot of additional features, such as support for todo.txt format, export to pdf, html and image formats (and yet it’s not all available formats). Todotxt support is great - markor can move completed tasks to the archive file, so your todo.txt will be always clean. The “quick notes” feature is also a great idea - basically it’s just a simple markdown file, but in the app you have a separate button to open it quickly.
DroidFS
DroidFS allows you to create an encrypted container, where you can put all sensitive stuff. Supports wiping imported files from the phone memory.
Etar
A good calendar app. Nothing more, nothing less.
Foobar
The old good foobar music player.
