Customer Reviews

Great feedback fighter

I use it on my iPhone 6 to quickly pick out resonant notes in my PA system when setting up for a gig, and this app works great for that. The mics on the iPhones and iPads are not calibrated reference microphones, so the app is not accurate for ringing out a room for a perfectly flat response, but for this price I'm very happy.

Works great on my iPhone 6, but the screen flickers constantly on my third gen iPad since the latest update. The app is still useable though; the flicker is merely annoying.

Life saver

Accurate, easy, fast, flexible. I've used this both tontine a home stereo's graphic equalizer and to tell an incompetent sound guy where feedback was. Well worth having.

App Flashing

As a former audio engineer, I'm impressed with the app, especially considering the price. However, I'm having an problem with this app flashing on and off on my iPAD.

When I open the app Octive RTA it begins erratically flashing the entire screen which now makes it unable.

From what I understand, this is a handshake problem with iPAD's rotation.

Their support offered a quick solution by "turning the iPAD upside down" which worked for me as long as I kept it that way. They also assured me that a fix is coming.

Looking forward to that update!
