FANDANGO: Accepts PayPal. Users can go straight to the ticket taker to have device scanned with Mobile Ticket (at participating theaters).
RUNPEE: Tells you the best time to leave for a bathroom break. Also gives a synopsis of the first five minutes of the movie in case you're running late.
MOVIE NIGHT OUT: With Cinema Sync, suggests fun things to do before and after the show.
MOVIEGOER: Uses social-network sites to share moviegoing plans.
MOVIE PAL: Has audio recognition, so when you watch a trailer, it will later remind you when the movie comes out.
