Music theory can be empowering, exciting, and one of the biggest tools in your creative arsenal. Whether you already play an instrument or are just learning, Waay teaches you how to bring together notes into melodies, chords, progressions, and even songs. This is applied music theory—stuff you can take straight to your instrument and use.


"Absolutely phenomenal. This is better than any YouTube video, podcast, or music theory book I have read. This truly helps you find an actionable way to put music theory to practice. Within 48 hours using this app I have actually comprehended what is being taught with this app far beyond any previous comprehension for past products. Honestly they could charge more than double the amount and it would be totally worth it." —Artice, May 3, 2022

"It's obvious a lot of time, love and energy has gone into this app. It's very well thought out, easy to follow and keeps you coming back for more. The developer is super friendly and answers any questions you have. It's clear he has a real passion for what he does and genuinely wants to help out. Awesome work all round" —thatboyswiss, Jan. 8, 2019

"The app is very smooth, and a great resource for learning more about music theory. I found the scale exercises to be very helpful, and I suspect I'll go back to them as a way of keeping those skills sharp." —Sean Garland (iOS MARS)

"I have probably spent thousands of dollars perfecting tone on pedals, instruments, amps and apps, posters, printed media, online courses. The BEST PURCHASE has been your Waay app." —A.P., Apr. 1, 2020

Highly underrated app

I think this app is one of the best in the App Store for music theory. I don’t usually comment or give ratings ever, but I just have to make people more aware. I feel that they took a lot of time to make the videos and the games they have to make sure that you actually understand and memorize the lesson all together. I have looked at many videos on music theory and the circle of fifth and I feel that this is the most understanding way that it has been broken down to me. How you can’t continue the lesson unless you’ve reached a certain quota is perfect. The way the lessons are broken down into 5-6 minute videos is great for someone like me who loses his attention too easily. It always kept me coming back and wanting to learn more. The only problem I can see coming from the app is that maybe main hub screen is a little boring and can make you think that you aren’t gonna have fun while learning but I was really surprised when I started watching the first video. I hope to see more lessons in the future from this app!

Exactly what I needed

This app is incredible. If you’re anything like me, you’ve been wanting to learn music theory for a while and have been putting it off. Recently, I’ve had the desire to dig deep and really learn music theory. I was searching for a course that was clear, concise, and guided. This app fits the bill 100%. The lessons are very well presented and the exercises are a fun way to test and hone your skills. The developer has done an amazing job by gamifying the process and making your progress feel tangible and substantial. Then there’s the cherry on top: this app is a one-time purchase and the developer doesn’t collect your data! Seriously, this kind of honest business practice is unheard of these days on the App Store. A big thank you to the developer, and his two beagles! SUPPORT THIS MAN!

Amazing app by an amazing developer!

While the pricing has gone up in the past few months for this app, I believe it is well worth it. Music theory for songwriting is simply not taught like this on any other app, making this invaluable. The creator of the app is just one guy, yet he considers ALL customer feedback. For those who can’t afford to purchase the full app, a subscription for a month or two should be enough to get you through all the lessons and get some practice in.

If you’ve been wanting to write your own songs but didn’t have a strong music theory foundation before, this app makes everything simple and practical. I love it!
