Shopping TODO app for iPhone and iPad

Have you ever forgotten something in the store?
Have you ever gone over your budget in the supermarket and you realized at the checkout that you dont have a credit card with you?
Has your wife ever called you while you were on a way to the store just to say "oh, honney, just add this one thing to the list"?

Well, I know I found myself in this situation numerous times by forgetting something in the store, by going over the budget and by forgetting that "one additional thing".

This app lets you create your shopping todo list at home by entering the name of the item, quantity and (if you happen to know it) price. The great thing about it is that you can share the list with as many people as you like and you can all see the updates as they happen live.
Once at the supermarket, you can then check the item off your list and enter the quantity and price and the app automatically calculates the amount that you have in your shopping cart.

I hope you will find this app useful, as it is something that was missing when I was searching for an app like this.
