Habitica
Habitica is an open source habit building program which treats your life like a Role Playing Game. Level up as you succeed, lose HP as you fail, earn money to buy weapons and armor.
We need more programmers! Your assistance will be greatly appreciated.
For an introduction to the technologies used and how the software is organized, refer to Contributing to Habitica - "Coders (Web & Mobile)" section.
To set up a local install of Habitica for development and testing, see Setting up Habitica Locally, which contains instructions for Windows, *nix / Mac OS, and Vagrant.
