Game Motivational Apps

Dan has mentioned on Danswers a few times about Chains.cc as a motivation app that lets you track your progress on custom goals, and I love this idea. I need a kick up the ass to do things. The problem is that Chains.cc is for iPhones and I am on Android. I have tried using HabitBull from the Google Play store but it is really busy and I feel like the only thing keeping me honest is pure determination, which is sure to run out at some point. Chains has nice graphics for keeping your chain going which is something I would like but ideally I would like to 'gamify' my motivation.

What apps do you guys use and what is there that has a game component (e.g. gold or exp gains for doing your tasks). Preferably for android phones but a desktop app isn't out of the question.

Zombies Run! is about the only app like that I use.

@c0l0nelp0c0rn1: that is specifically for running, I was thinking more daily goals.

I will admit to not having tried it myself, but I've heard people say they like HabitRPG.

@greonhal: This seems great except the lack of notifications completely kills any potential.
