Chilli X has released "Done", a unique twist on a To Do List for the iPhone and iPod touch.

• Shake to sort - shake your phone and your list is automatically sorted - important items at the top, completed ones at the bottom
• Wallpaper - Done has a unique 'SnapShot' feature which captures your most important tasks and saves them to your Camera Roll so that you can set them as your wallpaper. This means that every time you turn your phone on you can see what needs doing at a glance - without even starting the application!
• Landscape mode - rotate the phone 90 degrees to access the powerful delete function - pressing a button has never been so satisfying
• Sound effects - checking items off, sorting lists and deleting items are all accompanied by pleasing sound effects.

The developers explain their application as not a simple To Do List app, but not one of the more complex apps such as Things or OmniFocus. Done (App Store link is available in the App Store and is priced at .99 cents for a limited time.
