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, customization, and cloud sharing capabilities.

Great free version, with some little changes needed for custom scales.

First off, one of the best tools for vocal warmups and practice. Very straightforward usage and for the free version, you get way more than enough.

Two issues tho, hopefully can be improved, especially if you're paying for the app:
1. There seems to be a delay when using this app over Bluetooth audio. Maybe it's how the app is relaying the audio, but when connected over Bluetooth, the first two notes in a warmup scale are rushed, almost like a triplet, with the remaining notes following the set BPM. This can get kind of distracting and makes it hard to be consistent.
2. The custom scales function is cool, but it needs more flexibility in terms of adding notes from more than just an octave and a half. For example, I want to do a blues scale and I need more range. Maybe add a sliding keyboard or at least a button for octave +/-

Other than that, overall great app. Well worth the price for the pro version to get rid of the ads. Even the free version is worth it!

Enjoying it so far!

Voice lessons can be costly at times, but most definitely a necessity for safety and improvements. I'm someone who's been doing lessons for years and needed something extra that wouldn't burn a hole in my pocket and I am loving this! Whenever I have time I lay facing up on my couch and I practice my scales and it helps improve my exercises in class.

This app is exactly what I was looking for. I’m a guitar player not so much a singer. I’m using this app to learn all the modes of the major , harmonic minor and melodic minor scales. The feature of being able to create your own scales (any scale) and then practice them until you really know it is invaluable. Great app. I highly recommend it!
