Works every time

I’m mystified at reviews that give this app anything less than 5 stars. It delivers as promised and works every time.

If then goto ,

Great app

Works great. Thank you!

Developer Response ,

Quite odd and unusual. Could you try upgrading to the latest version, or reinstalling the application, please? If the problem persists, please send an email to the discussion group, and we'll sort it out.



I don’t understand why most online apps are willing to transmit or post your location on other websites and yet this one, the most expensive one will not let you send messages or post your location on other APRS sites! Waste of money!
