WHAT: The Flight+ app offers up-to-the-minute info on delayed or canceled flights, whether you're the flier or the one picking up the traveler at the airport. It's available for iPhone and iPad and costs $3.99.

HITS: Not only can you look up a flight without its number and get instant information about its arrival/departure and gate/terminal status, you also can set alerts for real-time flight information. Track the flight's progress on a map or send updates to your phone or email inbox. The app is very easy to use.

MISSES: I use Flight+ in conjunction with my LoungeBuddy app. I would love for them to marry.
