Great free version, with some little changes needed for custom scales. – SWIFTSCALES Vocal Trainer Review

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!
