Here is a list of what I have found to be the best travel Apps for my iPad and one "don't buy". Most of these aren't free and some are expensive. In most cases I have purchased the upgraded versions and any add ins. I have put these in order of their usefulness to me. TravTracker Pro - keeps history of flights Con - flight map only shows single flights for any particular trip World Clock Pro - nice display of time zones Con - Clock positions have only two options FlightTrack Pro w/ all the add ins Pro - excellent display of all future flights, great functional add ins Con - No history, limited ability to hold lots of flights WorldFactbook Pro - great quick info on a country Con - none World Atlas HD by Nation Geographic Pro - Awesome graphics Con - no way to store google maps of frequently visited places Currency Pro - quick and easy display of multiple currencies Con - a bit buggy. FXware Pro - nice graphics, shows rate change, trend Con - no function for concise info, Maplets Pro- lots of local "hotel tourists maps" Con - none, they seem to be always adding more Tunein Radio Pro - great internet radio, function for "local" stations Int Herald Trib Pro - free Con - sometimes not everything loads KAYAK Pro - good starting point to find cheap fares Con - rarely will you actually book via them Disaster Alert Pro - Good localized info on disasters Con - If you watch the news you know the info already Don't buy: Journey HD Pro - seems to have most everything a traveler would want all in one place Con - it WILL overload and do nothing but crash once you start using it I have plenty more apps but this list is travel specific.
