I've written Mac character generation applications for Classic Traveller. Book 4: Mercenary, Book 5: High Guard (Second Edition), Book 6: Scouts, Book 7: Merchant Prince and Supplement 04: Citizens of the Imperium (including the Book 1 careers).
I've also written a Mac application for Traveller5, SectorMaker, which is compatible with most versions of Traveller.
I've written iOS apps, TAS Form 2 and Orbital Yards, for Classic Traveller and ArmorMaker, GunMaker, and VehicleMaker for Traveller5.
