    Why having all these functions as separate applications, eating up the precious memory of your Pilot. Put them all into the calculator, and your Pilot is going to have air to breathe again! Air comes with all these functions in 6kb!

    On the Pilot screen to the right you can see the Air Control Center, that lets you quickly navigate among the function sets. From each Air functions a tap on the @ sign brings you back to the Control Center (see below for the function sets).

    World Time
  • Displays local time in 12 cities of your choice.

  • Currency Exchange
  • Cross conversion of 12 currencies of your choice
  • Rates are updated and saved
  • Ongoing caculations with the amount

  • Timer Clocks
  • Two independent timers for elapsed minutes and seconds.
  • Timers don't stop by switching Pilot off.

    On the right you see a running timer value together with the last lap time.

  • Master Mind Game

  • Convenient ways to input the guess numbers.
  • Informative and scrollable display helps minding.
  • Reveal function and saving of game progress.

    On the right you see a typical game of MasterMind, won in four guesses this time. This is indicated by last digits after the decimal delimiter (1..2..3..4). The first and second digits after the decimal delimiter are the scorings of the guesses (first is how many digits match digits in the hidden number, that are also placed at the matching position; second is the number of digits that match, but not placed on the right position, ... you know, as it should be in MasterMind). If your guesses scroll out at the top of the stack display (they often do), you can get them back with the 'up' and 'down' scrolling buttons.
