Remindd: Super Simple Reminders via Email and Text [Video]

Remindd does one thing, and it does it well: simple reminders. Once you are registered, just pick a day, a time, a title, and that's really it - the reminder is set. But Remindd has a few additional features beyond email alerts, the big one being that it can send you texts that will tell you to feed your cat or visit the grocery store.

Be sure to set your time zone quickly; otherwise, your reminders will come at the wrong time (the default is Eastern time). Also for international users, texting is only available in the U.S. The developers, Raphael Caixeta and Josh Craddock, also included an archives feature so that you can see past reminders without them cluttering up your dashboard.
