Good morning Captain,
This app will let you copy fast ATC clearances, ATIS and much more. Stop using your scratchpad, its not a safe practice.
This App lets you take note even from the fastest ATC Guys out there, try it.
This is excellent werther you are taxiing at JFK, enroute to LA or descending towards Heathrow. You get a complete log of all your clearances.
Print your log and add your flight number. Its a great tool for any phase of flight.
