Yeah, this was one of the first apps that I downloaded when the App Store was just starting out. The dev, Cyrus, has been very responsive and has put a lot of work into this free app. I remember sending him an email a while back when one of my local theaters' listings was no longer showing up (there are only 3 theaters in my town, one of them being a dollar theater) and he quickly responded to the email with information.
I noticed the showtimes not showing up a couple of days ago, but today I checked out his website and he stated he might have it be Ad supported, which I think is no problem.
I've been using Flixster's Movies app as a substitute, and it works pretty good being that I don't currently use Netflix and don't need that functionality.
Probably the only thing I DON'T like about the Now Playing app is the icon.
