Excellent but needs 64-bit upgrade – Spectrogram Pro (with super-smooth 60Hz update) Review

As the title says, this is an excellent app. It's very hand to have around when checking for acoustic anomalies, or finding the latest hidden picture Easter Eggs in Aphix Twin's music. My only caveat is that the app is still 32-bit. That means when iOS 11 hits, this great app won't work anymore. That is, unless the developer updates it. So, my message to the dev team: please update this bad boy!
