Works great for me - 10/1/2016
This app works excellent on my iPhone 6 w/ iOs 8.3. The layout is wonderful and it seems relatively accurate. I run a budget live sound company and this app is exactly what I need. Not too much, not too little. No option to change colors of the display, but Im happy with the look, so it works well for me.
