A MUST-have application. For anyone who forgets things. By far the best GTD app for ADD people like me. One can enter in stuff in any format- via a phone call, SMS, email, their website, or the iPhone app- using voice or text and what else could you want? You can set up a default reminder for things, it gives you a daily memory jog around what's going on, and integrates with Evernote. Oh, and it's free (!) or has a Pro version that I bought for $25 a year, which is practically free anyways for such a great suite of services- AND it's usable from any phone, whether or not you have an iPhone or not.. AMAZING!
