Not a waste of time

Super useful for any sound engineer. Actually a reason to pick up my phone.
Devs: 1 bug so far. The "random" aspect of the answers in the eq quiz isnt so random. Its only the highest or lowest option when its 63hz or 16k, otherwise its always one of the middle 2 (out of the 4 choices). This is in easy and advanced mode. Takes a bit of the fun out of it. Small niggle, thank you for an app worthy of phone time.
