This small app allows you to create and share you shopping list with friends and familiy.
It allows you to create new lists only for yourself to keep track of all the things you want to buy.
If you want someone else to be able to look at your list and add or remove something, you can share the list by searching for the username and tap on 'Share'.
Of course, the list can also be unshared again.
Finally, the list can be ordered to move bought items back in the list (and more)
Have fun!
