This app is a game changer. Be consistent with it and it will change the way you hear music.” — JayAllDay “This is fantastic. I’m a bit of a workaholic, and blind, audio engineer. This is like the holy grail of an iOS game for me. It’s simultaneously fun and productive. I can play on the go to have better ideas of what I’m hearing on my phone for later correction in Pro Tools, or plug into one of my monitor sets at home to test my instinct... and it’s a game, with categories and scores. Much respect.” — justmikeaf “Trained me up well! This app helped me become MUCH faster with EQ, and helped me know with greater precision what I'm hearing all around .” — MarkBvllock ===== Quiztones Terms: https://theproaudiofiles.com/quiztones/terms/ Apple Standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is review sentiment: Quiztones at 65% against Equalizer Fx's 19%.
