RealADSB app is intended for stationary observers of local air traffic. It can consume traffic feed generated by adsb_hub server application. With some limitations traffic feed in SBS-1 BaseStation format (port 30003) is also supported. For example Stratux ADS-B device or ADSBx feeder can produce such feed.

You MUST setup traffic feed yourself using adsb_hub server application that can run on PC, Mac or Raspberry Pi. It can work on top of FlightAware, FR24 feeders or generate feed using cheap USB adapter and external antenna. For more information please check our web site

Commercial, private and military aircrafts are shown on map and in scrollable list sorted by distance from reference location. Reference location can be your current location or location of airport specified by 4-letter ICAO code in settings. Special button provides access to METAR and aircrafts below transition altitude will have altitude adjusted using barometric pressure of the airport. There is a way to search/filter aircrafts by tail number, callsign, type, altitude in both list and on map. Additionally 2 layers with airports and weather are available on map.

For each airframe following basic parameters shown:
* Speed, Altitude, Heading, Rate of climb/descend, Squawk
and for most of them there is additional information:
* Tail number, Callsign, ICAO type, Origin/Destination, Photo

If information about tail number or type of aircraft is missing you can easily add it right inside the app.

Other features:
* Quick access to online resources including FlightAware, Google Flights, LiveATC etc.
* Push notifications for special squawks 7500/7600/7700
* Imperial or metric units
* 3 types of map: standard, satellite and hybrid
* Sharing of map with aircrafts using standard macOS panel

What’s New

Version 1.109

* Updated database of airplanes: Boeing MAX, NASA U2 and so on

Very responsive developer!

Love this app. Connects to our FlightAware Raspberry Pi and looks beautiful. Setup was easy and Nikolay has been very responsive to some stability issues we were having.

Very cool

Not easy to set up but great help by the developer.

Outstanding application and support!

For iOS, this is _THE_ application to get as an ADS-B client. It's a beautiful application, especially in the iPad and there is even a an AppleTV version as well. The developer put tremendous attention to detail into this application and helped me to get the server side up and running on my Mac. Support from the developer is fantastic! It was an error on my behalf, I didn't realize that I had to run rtl_tcp FIRST before running the java hub server. I mistakenly thought that the hub server ran rtl_tcp on its own. I also needed to upgrade to Java8 on my Mac. The developer quickly and very kindly got me going in the right direction and I want to thank him again! Note that the server side can also be Windows based or even Raspberry Pi based as the hub is Java. It supports not only rtl_tcp, but dump1090, PiAware, etc, so it's VERY flexible and customizable. Kudos to the developer for using this component/modular approach! I'll probably move the server side from my Mac to a dedicated Raspberry Pi eventually. I'll also probably even pick up the FlightAware Pro ADS-B dongle (as it amplifies and bandpasses 1090Mhz) for even better receiving. I'm using the (silver) RTL_SDR.COM Blog dongle (with the 10' Omnidirectional antenna outside). It works VERY well, so I can only imagine how amazing FlightAware Pro will be. Perhaps I'll even go another step further and get the $40 ADS-B 1090Mhz antenna. Note that is not necessary (I'm getting very good performance with what I have now), but would take my reception out to MANY hundreds of miles. At that point, I'll make it publicly accessible via the app perhaps. (The app offers P2P servers and you can be one too if you'd like, check website for details on how to contact the developer.) This application is VERY much worth the $10 cost. However, read the website fully if you are new (like I was) to ADS-B. Don't get too intimidated, it's actually at the surface very simple. (It just requires a number of components.). Antenna -> SDR dongle -> RTL_TCP -> ADS-B Hub. Then it is just a matter of regular wifi networking from your iDevice to server (Mac/Win/RPi) and Bob's your uncle. You CAN even port forward (TCP 4567, defined in config file) from your router and access your home setup over the internet. All in all, very cool application, well worth $10, extremely flexible, and outstanding support!
