Todolist

A very fast, simple task manager for the command line.

Takes a bit of getting used to, but after that, it's a pretty wicked todo app.

Emoj

Find relevant emojis from text on the command-line

I'm really bad at finding the exact emoji I need, but this tool is a life saver for me - I just type a word and it displays all the relevant emojis. Neat!

Dryrun (Android)

This one lets you try any Android library with a simple command. All you need is a phone plugged with ADB and issue the command "dryrun [github link]" :) It saves a whole lot of time – about 10 steps according to the developer – and works with emulators too (Android Studio or Genymotion for instance). A must-have.
