WorldMate works for me and my needs (but as mikew99 points out with good arguments), it's not for everybody's travel needs or styles. For what it's worth, I've used it for years on both Android and iOS with never a crash (which I can't say for many applications of any sort.) I don't have issues with WorldMate's parsing of confirmation emails/itineraries, but I'm not looking for as much detail (prices, check-in times) as is mikew99 - again, showing that everybody has different needs. I like WorldMate's interface, stability (for me, though obviously you've had a very different experienece), and level of detail. On my last trip, I experienced my first glitch with WorldMate - it failed to pick up one segment of a two segment flight (out of four total.) That's the first time that has happened for me, and most of my flights are multi-segment (since AUS is my home airport, and has disturbingly few direct flight options, at least when I need them.
