Our first iPhone/iPad app is essentially complete. The version changed before we got it into the store, so we have to convert the Automatic Reference Counting and make it use all of the screen for iPhone 5. After that, it will be sent to iTunes. Two or three weeks later, it will be in the store.
It converts mixed numbers to their decimal equivalents. It can handle up to 16 digits in the whole number, 16 in the numerator and 16 in the denominator. It is by far the most precise converter of its type in the iTunes store. It also teaches its users how to do the conversion for themselves when they click the Learn button.
