Can't move it to external card. (Internal getting full). Abbreviations on top could be in bigger font and maybe nore intuitive. Also, after recent update it crashed after few seconds. 73 ha5mro

Excellent for just to look up instantly for prefix which it suffices, also giving DX cluster information and map couldn't ask for better.

Excellent. One of my most used ham radio applications. Would it be possible to add the maidenhead locator - even if only the first 2 characters - to any call-sign?

Great app which is easy peasy to use. Being able to use it offline is very useful and will be great for club radio nights when we're all scratching our heads trying to think where that strange callsign comes from! Keep up the good work.
