This app is amazing. In near real time, you can track any airplane in the air, or on the ground anywhere in the world!
Free on the Apple App Store, but also offers a Pro version for a price that allows you to search for flights by number,… The free version requires you to do it manually… but still very cool.
We’ve used it when traveling, or when others are traveling to confirm when a flight will land. The free version is accurate to within about 30 seconds in our experience.
You may have no reason to track the flights over any city in the world, but you will end up doing it. Extremely addictive and you can find yourself lost in time looking at all the aircraft. Amazing to see how many aircraft there are in the air at any given point!
