Google has made it pretty easy to create apps for their Android OS, that I am sure you have heard about, and possibly use.
I am a heavy user, and I'd like to try and make an LMR app, just for the fun of it. Or have yours on my phone?
But what on earth would be fun or possibly even useful?
Perhaps it's an all together stupid idea, because one can always just use the phones browser, and get "the real thing" there, even log in and all. Several of my posts have been made that way, from my phone.
