Flighty is a flight tracking app founded in 2019 by Ryan Jones, a former Uber product manager.
Users add a flight, or forward their booking email, and Flighty tracks it from check in to landing. It shows gate changes, delays and the status of the incoming plane, often warning of a delay before the airline does. Live Activities put the flight on the iPhone lock screen. A passport view shows lifetime stats such as miles flown, airports visited and hours in the air, and friends can follow each other's flights.
The free version tracks flights. Flighty Pro adds the advanced alerts and statistics.
