Agree with everyone else, the site could use better a better explanation of the benefits...but having said that, the app itself is amazing! Conceptually, the whole "it's been X days since you've done this thing"is perfect for a procrastinator like me. I typically just cringe/ignore/postpone calendar reminders, but seeing it this way actually makes me feel guilty...and that is a major motivator for me. YMMV but I love it.
