Really helpful

Finally, theres an app for this. *recommend*

Amazing help!

The OKN Strips were prescribed by my doctor. Its pretty incredible, and I dont understand all the reasons, but I have found amazing relief of pain, when I am consistent to use it 3 times a day!

OKN STRIPS

Great app. A request: a slower speed than is currently available.

No instructions

There are absolutely no instructions to tell you how to use this app. You click on a screen and stare at a dot in a grid and do what? Would like to be able to use full App versus just the lines going down screen. Not really worth my money or time.

Outstanding customer support

My doctor prescribed OKN strips after a head trauma. I had a question about using the app, so I wrote customer service (theres a link right where you download the app.) Within minutes, on a SUNDAY no less, the app designer himself emailed me back, and continued emailing with me three times until I was satisfied and had the answer I needed. Outstanding.

Optokinetic Drum

Great little tool. Different speeds also are a plus as is the ability to change color to red or black. Thanks.

Good App.
