So handy

I’m so glad I found this app. Whenever I hear a Q code I don’t recognize, I just fire up the app and find it. 😃 So helpful.

The reference tool I was hoping for

Simple and useful reference tool. Browse Q codes alphabetically or search. Tap to view explanation. Works fine on iPhone 7+ running iOS 13.2.2 and perfect compatibility with accessibility features smart/classic invert and voice over for visually impaired hams. I would be willing to pay for an ad-free version of this app if one were available, but the adds are not too obnoxious.

Only issue I’ve noticed is that nothing happens when you tap the “support” icon in the bottom left corner. Tapping “settings” in the bottom right only prompts you to enable/disable personalized ads. Some users may like a light and dark theme option but currently there is none.

Wrong Format!

You need to alter and revise this app to be setup like a reference book to simply flip a page or scroll down to be able to read and/or search for the appropriate Q signal to use, alphabetical order of course. Nobody is going to know off top of their head which Q signal would mean to shift channel or frequency or to acknowledge your last message. So, the end user must have the ability to reverse lookup or cross reference if there are similar Q signals that could be used in a radio transmission, like a dictionary or thesaurus. And it needs to be easy and fast to lookup. The way you have this app now is that the end user types in a Q signal hoping to find the correct or appropriate Q signal to use. This is NOT handy or convenient at all! If need be, you better utilize the Navy Pub ACP 131 to provide accurate and precise definitions for your Q signals in this app.

Useless

Why not include a list of all Q codes in addition to a search.
