I use Chordify often, especially during low-attendance jams to verify chords shown by Ultimate Guitar. The UG lyrics are usually right, but their contributors' interpretations of the chords to songs often leave much to be desired! I've sent in recommendations for changes to both programs.
In Chordify, most useful chord types are available and usually correctly detected, except for augmenteds. That 1-3-#5 configuration is not on the list. Case in point: Guess Who's 'Laughing' - augmenteds used throughout, but not detected by Chordify.
At my low-attendance jams (often just two of us!) I play an arranger keyboard, and spend too much time searching the 1000-odd style options for a useable style to deliver an appropriate combo for the song we choose at random from the UG list. I wish the UG &/or Chordify presentations would at least suggest a starting point: rock, shuffle, 6-9 ballad, beguine, etc. etc. Chordify does present the BPM of the arrangement (usually from Youtube) it magically deconstructs in its pro edition, which is useful.
Any other users of these great apps?
