This apps needs update!!!

I downloaded this app more than 1 year ago and never got an update!
Does this means that theres no change in any airports?
Im in PHL now in a restaurant that opened 8 months ago and is not listed in the app...
Please do something about this. Thats why we are willing to pay 3$ for an app!
Thanks!
