Underplane turns planes flying over your city into a game. It tracks nearby aircraft in real time, works out exactly where you need to stand to have one pass directly overhead, then gives you a countdown to race there before it flies past. No aviation knowledge needed — just run outside and look up. Existing flight trackers show you data on a map; Underplane turns it into something you actually go and play.
