Looks good, easy to use. 👍


Works great on iOS, user friendly, a ham radio operator must have that has a smart device. Lots of icons for every occasion, after call sign marker I use a lower case -i to indicate iPad or iPhone. On my ht i dont use a number due to it being my only aprs unit, but people with more than one number them.

The best


Hands down one of the best APRS apps on the market. Easiest to use and has every feature you could want or need. Was hesitant to pay with all the other free options out there but I’m glad I took the plunge.

Awesome App!


This app works like a champ. It's accurate, it's easy to use, and gives you the ability to track in real time. If you're an amateur radio enthusiast this is an app you'll want.
