I have collected cheat sheets since college for almost everything. Awesome site, and a great idea.

We integrated with Dopamine. It's dope. :) If you want to use variable reward schedules to improve usage and user compliance, check them out. They showed us results from both a test group and a control group. There was a significant improvement of user engagement in the test group. Very cool.
