The need of learning "irrational dots on diagrams" by heart is eliminated by understanding the simple logic of chord construction.

OneHour method is not a chord generator, but it turns your brain as one. In one hour you’ll throw your 256 pages 10 000 chords chord dictionary into the fireplace and laugh at chord generators.

"An absolutely genious way to learn chords, and not just chords, This method unlocks the pattern / chord-shape-stuck guitarist's thinking and allows one to construct chords, scales and arpeggios easily and in the most logical way possible. It helps one to understand why certain things sound how they do and helps to see how intervals, chord shapes and inversions are connected to each other. Honestly, this method is all you need to learn ANY chord or arpeggio there is. Most importantly, the method is FUN, rewarding and once the method is learnt the system starts feeding itself, so you'll never ever forget what you've learnt with the method, you'll only get deeper in seeing how the fretboard works. Sounds too good to be true, I know, but I learnt the guitar with the predecessor to this, the Only Complete method. Understanding chords, arpeggios and scales through the method has been the biggest "EUREKA"-experience for me in my 15 years as a professional musician. It made me realise that chords or scales aren't hard, they're completely logical and learning them is easy. This method unlocked the fretboard and the how I approach the guitar in general for me, I highly recommend this App to everyone, from beginner to pro player."

Great but not worth the money for the extra features that should already be included

Great app, would love to have the advanced features considering the fact that I tune down a half step, play a few things in drop D and use a capo from time to time, but there’s no way I’m paying $5 for those features. I can’t afford it at the moment and probably wouldn’t pay that much if I could. Great for theory, but doesn’t work side by side with my guitar or with my setup.
Will continue to use for theory because I haven’t found a better app for that yet but if I find one that I can get what I use in this app as well as the features I’m looking for, I will probably remove this app.
Unless you all include these features for free before then

Music Theory Tuition Paid

Truly awesome app that not only identifies chords and lets the user have full authority to build extremely complex chords but also serves to “truly” teach the user “music theory” while simplifying complicated chord progressions.

I’ve reviewed other sources and found by far that the “one hour method” app is the most accurate and user friendly.

Highly encourage upgrading to include the “capo,” “special tuning,” and “chord guesser.” Also truly take advantage of the required short lesson prior to using the app and utilize the educational lessons and tutorials included with this app.

Helps Creativity

Utilizing the One Hour Guitar method allows you to learn different versions of chords in a way that is simple, and easy to understand. Learning and applying these different versions adds depth, interest, and creativity to songs you currently play and/or are writing. I like that you can strum the virtual guitar to be able to hear and understand the chords you're learning.
