Appigo's Todo for iPad complements their existing Todo for iPhone app very well and if you already use Todo for iPhone, you will be quite pleased with the iPad version. If not, you'll certainly appreciate Todo for iPad on its own merits.
One of the first things you will notice is the aesthetic; Appigo went for a traditional three ring binder look and feel. You can change the color of the binder, paper and rings in the settings menu. Appigo promises more themes in a future update.
Outside of looking pretty, Todo gets the job done just like its iPhone cousin. You can create a your standard task, project, checklist, contact or website. If you are a Getting Things Done (GTD) user, you will be happy to know that @contexts as well as tags are supported. Holding the iPad in landscape gives you full view of all your task information. On the left side you have your lists, Inbox, Starred and Focus list. Let's discuss this in a little more detail.
