Ratings and Reviews

gee-see ,

So far so good!

Been looking for a good APRS app since I switched to an iPhone a few years ago. This app is a big step in the right direction!

4 stars for now to give room for improvement. The app is super easy to use and I was up and running in less than 2 min! It does 80% of what I want out of the box. Awesome!

Constructive feedback that would get me to 5 stars:

- it needs a messaging interface. A way to send / receive messages between stations or receive bulletins. And a way to view old messages / threads. Similar to the Messages interface on iOS.

- please let us display the call sign of a station on the map. Or make that a configurable option.

- please let us configure the distance to filter packets on the APRS-IS network. I might want to see more / less than 100km.

- please add the ability to beacon automatically every x min or x miles or something like that.

This is definitely a step in the right direction and could fill a huge void on iOS for APRS apps. I’d definitely consider paying for more functionality. Thanks!

I was getting this set up and clicked the RF receive button at the bottom. The app crashed and no longer opens even after a manual app kill and relaunch. iOS 12.0.1 6s
