An app that I can put in a specific day and time and it will send me a notification? Is there such an app? Thanks.

i've tried using the calendar app.

you can set the alarm. and it will notify you, that is if your ipad is turned on

Yea, I'm disappointed in the complete lack of a timer app. I really want my iPad to be like my iPod touch and iPhone where I can set a countdown timer.

Reminder on iPad i have not yet use before, but for iPhone, I am using SnooziCal, it is very useful.
