Has anybody used ukecanplay.com software?

I saw this advertised on ukuleleunderground, clicked the link and it looks like a good tool for learning chords. Has anybody else tried it. Wanted to get some opinions before plunking down $30. Thanks

Yeah, I have it, it's a good learning tool for me in that it makes me pay attention to chord shapes. I like that I can choose to play a succession of minors for example by picking that specific group, or all the A chords, etc. Also being able to test myself is fun. I got it to make my brain work a little harder in a different way, not that this isn't hard enough already for me! It has a different approach to learning than simple chord charts because it requires more effort. I'm happy with it for the price. However if $30 is a lot for you right now, maybe a book would be better. But if it's only a couple hours at work, then I'd say go for it.
