First of all, let me start by saying...IT'S FREE!!!
Cozi let's you type your lists up on the computer, and when out and about, pull them up on your phone. No more forgetting your list. Also, calanders and journals too..and you can sych to your whole family's phones easily so that when you make an appt, they can view it, or you can alert their phone's that it was made.
If you have a smart phone, I know you will love this app as much as I do.
