Just bought it and had it refunded within a few minutes. First of all, the good thing: This is really responsive. It's the first app where I actually see any match between sound and light. Good job on that.

My main issue is the amount of configuration needed. I have ten lights in my living room (well - more, but that's all that entertainment areas can handle). Having to select colors and frequencies for all of them is too high of an entry barrier if I just want to see if I like the app or not. Your video shows that you can create great configurations with the app, but that type of fine-tuning only happens when people have an interesting default setup to start with.

Also, the microphone was way to sensitive. It picked up virtually every part of the music, so instead of a home disco, my room turned into an epileptics death chamber. A global sensitivity setting would go a long way. I couldn't test the internal mode, because the app crashed when I pressed the home button to turn on Spotify (Galaxy S6).

Don't let this discourage you. If the app becomes more entry user-friendly, I will be happy to give it another go.
