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.

Verdict

The call

The clearest difference is rating: RUMlogNG2Go at 4.7 against ACARS's 3.0. RUMlogNG2Go also leads on review sentiment (74% vs 41%) and update cadence (every 4 weeks vs every 12 months). ACARS's advantage is price ($2.99 vs $4.99) and iOS requirement (6.0 vs 16.4). On ads, in-app purchases, monetization model and device support there is nothing between them.
