-- Bgirlz, 2024-07-10

### *---- "Don’t want to keep paying for this and can’t figure out how to uninstall"
Dont want this app
-- f stitch Fish Bo, 2022-07-30

### ***-- "Want horizontal stripes"
Mine will only display vertical stripes and I need horizontal as well as vertical for mdds symptoms. I am not sure if that is possible with this app. If so, I don’t know how to do it
-- megletr, 2021-12-26

### ***** "OKN strips"
This  works quite well. Tap the screen to make the strips go faster. Level 1 through 5. I’m using this app to treat my nerve/ muscle paralysis in my left eye.  It was recommended by my therapist.  This exercise and time and hope.
-- JohnKrunch, 2021-03-07

### *---- "No instructions"
Useless without
-- chennen2, 2018-09-05

### ***** "Breakersmoon"
Great app!  Has corrected my issue with left hand shaking.
-- Breakersmoon, 2017-11-20

### *---- "No instructions"
Useless to me without instructions on how to use it
-- Jacob91999, 2016-03-29

### ****- "Good app"
Red-Black inversion doesn't work on grid test but otherwise a good app. You can get back to main menu from optokinetic by holding down on screen for two seconds and the back menu appears.
-- SpaceSnaxxx, 2014-08-17

### ***** "Good"
Good app.. The only complain ill make is after opening the OKN strips if i need to go back to the menu containing amsler grid , i can only do so after i quit and close the application and open it again.. But its a minor complaint and i like the app.
-- kalsajja, 2014-07-22

### ***** "Good App."
Good App.
-- Bossy gamer, 2014-01-22

### ****- "Optokinetic Drum"
Great little tool. Different speeds also are a plus as is the ability to change color to red or black. Thanks.
-- rsjung80, 2013-10-01

### ***** "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 (there's 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.
-- CherylHunter, 2013-03-12

### **--- "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.
-- Samie1968, 2013-02-06

### ****- "OKN STRIPS"
Great app.  A request: a slower speed than is currently available.
-- Andy A A, 2012-12-24

### ***** "Amazing help!"
The OKN Strips were prescribed by my doctor. It's pretty incredible, and I don't understand  all the reasons, but I have found amazing relief of pain, when I am consistent to use it 3 times a day!
-- Jjjoy, 2012-11-18

### ***** "Really helpful"
Finally, there's an app for this. *recommend*
