Shared shopping list for you and your wife (and vice versa) ...
There is no need for more notes / Smsim / and Oatsafim etc. - just add an item to the list, and is updated at all!
To share list, two sides (or more) to enter email and password (random) are identical.
* Quite simple!
* No advertising :)
* Highlights: email and password used to identify the list, and nothing else.
