You know what would be really cool? 

An app that you can select specific criteria for, that then coordinates your calendar and keeps you on track without a constant need to be manually updated. 

Something that can read your mind, and then predict what you will forget and conveniently remind you so you can keep steady and not forget stuff, like what day your kid has PE and they need to wear their PE uniform.

AND bonus, it tells you WHICH kid it is that has PE. 

Or that you bought enough beef to last a month but keep forgetting to stock up on chicken, so then you eat beef 3 days in a row before you get a chance to pick up more chicken. 

Only to encounter a sale for beef...

Something that can quickly locate your keys that are sitting on your dash board in your car because there was a mini crisis involving a super bounce ball, a jolly rancher and a pencil with no MacGiver in sight. 

Or possibly help you find your phone because the "find my phone" app swears your phone is in the house, but can't tell you its sitting next to the keys you can't find either.  And since your car door is closed, you don't hear the really cheesy ringtone you just recently downloaded as your try calling yourself to hone in on your phone's location.

If it could do the dishes and fold the laundry, that would be cool too.
