If you like this app, here's an extra tip for you: When the magic square that totals their age first comes up, hold down the home button and then push the top button. This will take a screenshot that you can e-mail to the person for whom you're performing it. There's an app called PhotoMarkr that you can use to add your contact information to the picture as a watermark!
