Jumbo Calculator

Jumbo Calculator is great for those with failing vision (and an iPad), or those who just want the ease of use of a large buttoned calculator. While sadly you can't feel the exquisite texture of Jumbo Calculator's plastic buttons and the included solar panel doesn't actually hold charge, Jumbo Calculator still succeeds at its main purpose: adding, subtracting, multiplying, dividing, squaring and square-rooting.

Shuffle

Rather than going through your music library one song at a time, Shuffle gives you four choices to pick the next song while the current song continues to play. If you don't like your choices, simply shake or hit the shuffle button to get four more. This makes Shuffle perfect for when jogging or other times you can't be bothered with handpicking songs, but still want to be in control of what's next. At only $0.99, download Shuffle on the App Store today.
