This is utterly useless as a tool. More like a cartoonish visual with no way to see results frozen or saved. The screen went to half size and had to restart to fix. No options like calibrate or any choices of settings available other than colors and which test is shown, the upper right drop down is blank. Free app needs to run perfect to sell other simple add-ons that are commonly built into hardware. Limiter, compressor etc. Digital EQ with analog sound? Good idea since digital EQs are junk.
