First make sure you can get the RF from the planes as high quality as you can (good antenna, receiver tweaks).Then it will require various experimenting placing the iPhone in good position so the phone mics can hear the transmission. And also experiment with the receiver’s volume.You will see the data scrolling on the phone screen if you get all of the above correct. Now look at your data for quality decodes. If the data looks garbled, play around with the settings and positions again.And....in the app’s configuration, make sure you have a file selected to store the data on the phone. Another thing I really dislike in the app is that if you open another app, all the data displayed in the ACARS screen goes blank and then if you want to view the data, you have to open the stored data files. It does this everytime you goto another app on your phone.I want to try this app after adding an external microphone to my iPhone 8+ via a splitter cable. I really hope this will help with the decoding of crap data to quality data.Good luck - when all is tweaked correctly, it is a great app. But honestly, use PDW on a PC.

VERY minimum application, it receives ACARS and that's it. You can put your earbud microphone next to radio speaker, but best bet would be a line-level microphone input. Even if packet doesn't fully decide properly, you get what does decode. Thats a plus. Wish it could run in the background. Only thing I understand is Tail number and type aircraft in packet. It would be nice if the rest of the jibberish is translated to what it actually means. However, it does work. I use in with SDR on the Airband.

Needs support for Apple Watch

I’ve tried other ACARS decoding software and have been disappointed, but this app worked reasonably well. My only wish would be for it to work in the background.I’ve already had $3 worth of fun with it...
