This app is great; I've already shared it on Facebook and in person. One thing 2 of 3 people I shared with wanted was multiple user profiles. Not just for multiple people; but so a single user can track his calibration in the morning vs. the evening; under different emotional states and amounts of stress, etc.
Interesting. I haven't heard anyone else request this feature, but I'll add it to my TODO list and might get to it eventually. Thanks!
Hey rationality friends, I just made this FAQ for the credence calibration game. So if you have people you'd like to introduce to it --- for example, to get them used to thinking of belief strengths as probabilities --- now is a good time :)
