Sure. So in my previous iterations, I was thinking of taking user input and understanding when people needed goal reminders, but I've found out that sending random reminders throughout the day works out even better. The theory behind the site is that by consistently remembering your goals, you'll achieve them. So "the right times" ends up being randomly throughout the day when you're probably not thinking about them. I like this solution because it's really simple, quite random, and notifies the user at unexpected times (only between 8am and 9pm in the user's timezone, though. Mr. Goal minds his manners). I wasn't sure how to explain it on the front page, would you have any suggestions?
