PredictionBook app?

[msmith25]

I think it'd be really helpful to have an app (ideally for both Android and iPhone) that lets the user submit predictions quickly and easily throughout the day. I find that it's a bit of a hassle to find the right spot on my phone's browser and then type in the prediction, enough so that I hesitate to put in predictions about (say) how much the grocery bill is going to be while I'm waiting in line at the checkout. Having the app give reminders to pass judgment and giving the option to quickly pass judgment would be great! And it'd be convenient to have a quick display of one's personal degree of calibration.

I personally would love to see the ability to use my Android's Voice Search feature to say the prediction and have it appear for me to submit, much as the Remember the Milk widget lets me do with to-dos. But I suspect that'd be asking too much. :-)
