Easier Than REW, Less Expensive Than Dirac

I’m really impressed by this app, it just makes everything so easy, just like it should be. Setting up a mic? Easy. Running a sweep? Easy. Generating a response curve? Easy. Copying that curve into miniDSP PEQ settings? Easy. Getting stoked on how your system sounds after setting up your new PEQ? EASY.

Good job!

This is a great, easy to use tool. Just invest an hour reding the directions and you’ll be good to go. It made my expensive stereo sound like I thought it should and could sound. Sound went from good to amazing. It also helped me fix a large bass dip 14 db at 125 hz. Moved my speakers closer to front wall to get it to 8 db and was able to correct it to 1.5db dip. Nice

Good app that I’ve seen that uses the iPhones microphone

A microphone is more than good enough for simple, manual EQ, but most apps don’t use it or don’t compensate, this app does both and for a decent (at least when I purchased it). While not exactly necessary, I do wish that they added true support for headphones.
