About this app

SWIFTSCALES was created by singers, for singers, and is the first app to simulate sitting at the piano with a vocal coach. Unlike other apps & audio lessons, SWIFTSCALES moves with you, as high or low, fast or slow as needed. You control every session in real time or passively, the only limits being the 88 keys of the piano and your imagination. No musical knowledge required! In fact, vocal coaches themselves can use SWIFTSCALES on the go to train and warm up students with exercises they already teach thanks to the app's endless flexibility and customization.

Whether beginner or master, student or teacher, SWIFTSCALES grants a lifetime of ever evolving vocal training. Singers, this is the app you've been waiting for!

Not what I expected - thought it would have a variety of built-in scales... but it misuses the term... what it calls scales are just simple vocalise patterns... all the prefab ones are based solely on note selections from the major scale. If you wanted to practice, let's say, Harmonic Minor you are out of luck short of using it's custom feature to build it yourself. Okay for what it does, which is not much.

Love the ability to customize. It would be nice if there was a way to set an uper limit on the exercises though. Currently you can set the starting note, but it just keeps going until you manually shut it off. It would make the routines much more convient to be able to set a range for each exercise. I love that you can make your own scales though, its very helpful!

Glad you like the customization options! Yes, I've been wanting to work that in without overcomplicating the interface (basically, allowing a user to still control the flow in real time and/or let it rise and fall completely automatically, like you are talking about), and think I have a way of doing it. Happy singing!

Thank you Swiftscales! I absolutely love this app and I've told all my singing friends so too! Swiftscales is a major part of my 'go to' daily vocal exercise regime. It is convenient, easy to use and thorough. I showed it to my voice teacher and she says that the exercises are sound (lol). However, as I advance through the preset routines, I find that most of the exercises are way too fast for me to maintain good technique. To solve that issue, I intend to have a go creating my own routine.
