This is kind of cool but there are other good tools for it, as commenters mentioned. (Seatguru, FlightAware.) I think the missing feature there is simplicity and “so what?” Tell me why my a321neo is so cool, how to tell it apart from other planes when I see it on the tarmac, when it was designed, how many are out there, which airlines operate lots of them. Others will beat you on feature richness, but I just want an app I can use to teach my kids about planes, and geek out on them myself.
