Intonation tool! Vocal Pitch Monitor (Android app) -> Evaluates your intonation while you play

I found this app that records your playing and places the tune on a spectrum that allows you to evaluate your tuning over the whole recording. It is an Android app called "Vocal Pitch Monitor". I have worked with a tuner but when I check my tuning note by note I tend to play to the tuner needle. It does not help with knowing how my intonation is while I'm moving from note to note. This app helps visualize the tuning note by note, and it is free!
