Shows aircraft traffic from your ADS-B receiver (supporting GDL 90)

Requires iOS 13.0 or higher and a GDL 90 compatible ADS-B Receiver. Available for iPhone and iPad.

Receives and displays aircraft traffic data on map from ADS-B receivers (e.g., Stratux) which support GDL 90 protocol output).
Expects GDL 90 data to be sent to port 4000 via UDP (which is usually standard; but can be changed in the app). Works entirely independent from internet connection (except for Apple map data; simple built-in map can be used instead) and with ADS-B receiver only.

It also includes an attitude and heading reference system (AHRS) including airspeed, altitude, and heading as well as display of METAR/TAF (one-time unlock necessary).

The map display can be customized in different ways:

  • Use top corner buttons to:
    • configure aircraft data (altitude, callsign, climb rate, or speed)
    • show distance rings (10, 20, 40 NM)
    • change map type (Apple map or simple built-in offline map)
    • tap on location button to toggle between tracking and none-tracking
  • Tap on bottom right legend plate to toggle between speed and altitude
  • Display of surrounding airports

The top center view shows own aircraft’s speed, track, and altitude. It also show number of satellites seen and used for tracking.

Unlock Data/Functionality

(available in Status > Settings)

AHRS and weather data can be displayed thru one-time unlock purchase. Currently supported are METAR and TAF. Additional airport data like runways, AWOS is also available thru built-in database (no Internet access required).

NOTE: weather data is available in areas with ADS-B data coverage. Please check before purchase, otherwise no weather will be shown.
