What is flying overhead? SkySight helps you explore nearby aircraft on an ADS-B flight map and understand the available data behind each marker. FROM MAP TO FLIGHT DETAILS Browse aircraft positions, tap a plane, and inspect available callsign, registration, aircraft type, altitude, and speed. Altitude-colored markers and a sortable aircraft list make it easier to explore what is around you. START WITH NEARBY PLANES Basic aircraft tracking and live map updates are available without a Pro subscription. Feed coverage, aircraft visibility, and update timing depend on the available data source and your internet connection. SKYSIGHT PRO Optional Pro access adds aircraft follow mode, flight history where available, convergence notifications, additional filters and supported global/emergency views. See the in-app plan screen for current features, price, and renewal period. Subscriptions renew automatically unless canceled in your Apple account settings. READ THE SKY, NOT A SAFETY GUARANTEE Aircraft may be missing, delayed, or incorrectly identified. Not all planes transmit data that is visible to the app. Positions and alert calculations can be incomplete or stale. Convergence notifications describe computed proximity, not verified collision risks or official emergency warnings. SkySight is for aviation interest and plane spotting. Do not use it for air traffic control, navigation, flight operations, or safety-critical decisions. It does not identify extraterrestrial craft and is not affiliated with competing flight-tracking services.
