    So honestly I haven’t even really used it that much but I do indeed know exactly what this system accomplishes and that it does it well. Really a great tool! In a nutshell this app will show you exactly how your chords should change and how it interacts with “beadgcf” or (the circle of fifths) rendering the way we think about music into a new form of algebra (if you get me), appropriately without having to think too hard and that’s really cool. The scales bank and chord shapes puts my thick chart book in my pocket. Thank you for this app.

    Who Made This App?!

    You’re an absolute genius. Thank you. By far the greatest app on my phone. I don’t like paying for apps but this one is priceless. The knowledge it gives you in real time takes most people, like me, a lifetime to learn. If you are a Music Producer, this is a necessity.

    Fantastic Experience

    I’m an absolutely beginner to music theory, and I’m just giddy with this app. Incredibly fun. It takes a bit to figure everything out, but once I got the hang of it, man. Really great. Thanks for this guys.
