What’s New

Version 3.0

* The Scales app now has a fresh new coat of paint! In addition to fitting in more with modern iOS design, you may find more control at your fingertips with fewer button taps to streamline your practice routine.
* In further effort of streamlining things, there is now only one In-App Purchase that unlocks all of the content for a reduced price: Scales Pro! Check out the store for more info. Note: if you bought any previous In-App Purchase, you now have access to all of the content :)
* Finally, you may find the app runs a lot snappier due to some performance improvements and bug fixes under-the-hood.

Happy practicing!

Keeps crashing

Ever since the last update, the app crashes every time I try to open it. Before this, it was extremely useful and well-designed, and I recommended it to several of my friends. Please fix this issue so I can use this app again!

Developer Response ,

Hey Jazzyj, sorry for not reaching out sooner but the app no longer crashes! I fixed it a year or so ago, I just didn't reply because I didn't know I could haha. The latest update also includes a ton more neat features to help you practice better too, hope you enjoy it! Happy practicing!

One of the best practice tools to hit the market!

This app is an incredibly diverse and effective tool for practicing scales. The new features have taken it to a whole new level. I recommend this app to every single one of my students, from beginners to college level music majors. It is also particularly useful as a tool during lessons to help test students on their scales. With the addition of the built-in drone and metronome, this app has now become a staple in my own warm up routine, shaving time off time in my scale practice and making drone work much easier! Be sure your phone is not set to silent/vibrate when using drone/metronome.

One of the highlights of my practice time!

This app has changed the way that I look at practicing scales. I used to have a really difficult time and always dreaded my practice. I would also get into the habit of just playing them in order, which is never now they were expected to be performed in my juries. Carson’s app makes scales a challenging and exciting part of practice time! I will definitely be having my students use this app!
