Beautifully! The app’s homepage shows a button, ‘Add New Item’. Select this and key in the item you want to buy. When you’re finished typing, select ‘Done’. The item will appear on the list in a yellow button. To add another item, simply click on ‘Add New Item’ again and key in another item, then click ‘Done’. If you want, you can remove the item by selecting it then clicking ‘Delete’ on the bottom left of the screen. 

You can move an item up or down in the list by clicking on the item, then selecting ‘Move’ at the bottom right of the screen.  

When you are shopping, you can go to an item on the list and click ‘Done’ when you’ve purchased it. The yellow button for that item will turn green and the item will be crossed out. If you’ve made a mistake, simply go to the crossed out item and click ‘Done’ again. The crossed out green item will turn yellow and the line through it will disappear. 

‘Options’ on the bottom left of the screen allows you to send the list to an email address (if you have not set up an email account, you will be prompted to set one up at this point). You can also choose to save it (it will be saved in your phone as a .txt file) or import a list from the files in your phone.
