Simple yet vast

I downloaded this app thinking it was just another cheap-o guitar app that wasn't what I wanted, especially since it didn't have any reviews yet, but I was amazed!!! It's incredibly easy to use, if I'm jammin on my guitar and find a chord I really like I just go to this app and find out what it's called in 5 seconds. But it isn't just for this either, it has a chord dictionary by chord group containing literally thousands of different chords... This is worth way more than a dollar

Chord Cracker Series

Most colorful and useful tool for both Guitar and Uke. Had to check out every app to find a uke app with capture. Has a great feature in finding roots and chord structure. Great theory built in, but both lacking higher than 3rd fret database. Just shows blank without name. Only some work up there. Hope updates will include those. Also analysing individual notes could be improved. Strum field could lock up on the second strum so notes don't jump to top!

Finally some one did this

As a player who plays in different tunings and with a capo a lot this is a very useful app. Capo charts don't always tell you the exact chord you play and this will fix that immediately. This is the perfect app and well worth the dollar I spent on it.
