The native Tasks application on BlackBerry is great for keeping organized, but if you want something with a little more "juice", Lister may be just the thing. The free app lets you create and manage multiple lists for anything from to-do's to Christmas Lists to reminders. You can easily create a list, add due dates and reminders, and navigate with multiple hotkeys. With Lister you can also share items with friends and family, even if they don't have the application. If they are a Lister user however, the app will open up the shared list automatically. Overall a very cool app that can help you keep track and stay organized - so far its made a great shopping list for me. You can grab Lister totally free from the CrackBerry App Store.
