RemindYou from Make Your Day Media: The concept behind RemindYou is remarkably simple -- essentially, its goal is to make sure you never miss another appointment ever again. And how does it do this, you ask? Well, by syncing up with iCal, Outlook, or Entourage and then overlaying a graphic of all your appointments over the iPhone start-up picture. Thus, instead of seeing a picture of the Earth from space as your default start-up screen each time you unlock your iPhone, you'll see a list of all your appointments. RemindYou can be purchased from the iPhone 2.0 App Store for US$19.95 for a lifetime license.
