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.

Read full description

The ParksnPeaks app allows (Australian & NZ) amateur radio operators to alert, spot, log and chase portable radio activity. There are two main types of activities, Summits on the Air (SOTA) and World Wide Flora and Fauna (WWFF). SOTA is an award scheme for radio amateurs and shortwave listeners that encourages portable operation in mountainous areas.  WWFF is an international program where Amateur radio operators are encouraged to operate portable from designated nature parks and protected nature areas. The Parks & Peaks app brings a convenient interface for these activities to the iOS user, both activator and chasers alike. Users are presented data formatted for a small screen from the Parks & Peaks website (http://www.parksnpeaks.org) and are able to view and create spots as well as alerts and it also contains tools such as Find Sites to support the activities. This version allows entry of QSO logs which can be exported and emailed to the appropriate award websites or managers straight from your device. Logs can be exported as ADIF or CSV.   Mapping of parks and/or summits is now included and you can plan your trip by viewing other sites around the one you plan on activating.

The call

The clearest difference is price: Parks & Peaks at Free against ACARS's $2.99. Parks & Peaks also leads on review sentiment (86% vs 41%) and rating (5.0 vs 3.0). ACARS's advantage is ratings volume (14 vs 1) and iOS requirement (6.0 vs 12.0). On update cadence, ads, in-app purchases and device support there is nothing between them.
