I used to use the ACW all the time and it's a really useful app when you get it to work. Unfortunately I haven't now used it for a few years since it was "improved". I'm sure whoever changed it thought they were making it better, but as far as I'm concerned they really completely ruined it. No matter what I do I cannot get it to work. I'm now forced to use an app on my phone called Chord AI which is very good, but I then have to transfer all the chords onto my laptop - so thanks to whoever it was at PGmusic who had the bright idea to mess with this previously great app.
