I tried the pro version with one-month subscription for $4/mo US. It does better on complex chords than the free version but still misses a lot. I get a straight 7 chord when it's a 13, or a m7 when it's a m11, that sort of error. However, this may be more accurate than anything else I've used. More tests needed.
