In looking around the app store, I found a tournament app by the National Pinball League.  I checked the site at nationalpinball.com.  National Pinball League is a group dedicated to supporting competitive pinball.  They certify locations and hold sanctioned tournaments.  Their calendar currently does not list any upcoming tournaments.  I have registered as a member and will post about any upcoming events.

One of the certified locations is The Pinball Gallery in Downington, PA.  I visited The Pinball Gallery in 2012 when I was working in Philadelphia.  It is about a half hour drive from Philadelphia and can also be reached by train from Philadelphia.  When I was there, all of the machines were in great shape and played without any problems.  When I was there, they had 14 or 16 machines.  I spent an afternoon there and had a great time.  They had a mix of newer Sterns and 90s, 80s and 70s Bally and Williams titles.
