Want to display ACARS transmissions, without using a bulky computer? ACARS lets you view ACARS aircraft transmissions on your iPad, iPhone, and iPod Touch.

A radio/scanner capable of tuning the 118-136 MHz aircraft band is required. Just set it next to the radio's speaker, tune in an ACARS frequency, and watch the decodes. Or, for even better reception, use a pair of earbuds, plugged into the radio’s headphone jack, rather than the internal speaker.

You can save decoded ACARS packets to a file to view later, or transfer to your computer via iTunes.

Aircraft model information for many planes in a built in database is displayed along with the decoded packets. You can also add your own plane information to the database.

Packet fields are color coded on iOS 6 and later.

Buy your copy right now, and start decoding and displaying ACARS transmissions in minutes.

It's a nice start....

Having seen Black Cat Systems Multimode, I figured that I'd be getting similar quality in thus app....Well, it's a nice start, but it's pretty clumsy to exit this app when it's running (you press the button and bail out completely). Also wish there more options to save the received ACARS text as well as pause operation, too. The decodes are sometimes garbled even when there is no background noise present, but for the most part can decode ACARS reception decently. Here's to hoping the author adds some more features to this first effort to improve its operation.


Requires some audio tweaking

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. 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.

It works.

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.
