## OptoDrum Description
OptoDrum is an easy to use replacement for a bulky optokinetic drum or a fraying cloth tape to elicit optokinetic nystagmus for evaluation of neurological, otological, and opthalmological disorders.   Simply place the iPhone with a moving pattern in front of a patient’s eye to elicit the response.  The stripe pattern, width, and speed are easily adjustable.

• OptoDrum provides five patterns:  black stripes, red stripes, mixed colors, symbols, and animals.

• Drag a finger up or down the screen to make the pattern move at the speed of your finger.

• Double tap the moving pattern to make it stop.

• Pinch or zoom the pattern with two fingers to narrow or widen the pattern.

• A left or right finger swipe switches a stopped pattern to the next one in rotation.

## OptoDrum Reviews in United States

### *---- "Waste"
Doesn't work as described. Can't switch pages to use different frames. Can't double tap to stop, have to close out and reopen to use another frame. It does not go as fast or as slow as you swipe.
-- HiyaUser, 2023-08-06

### *---- "No"
This is a rip off. Double tapping does not stop the pattern, so you can not switch patterns or colors. Very unresponsive to all touch commands instructed, in general.
-- tkmcg85, 2021-06-01

### *---- "Worthless"
This app does not work as described. I want a refund please!
-- 22zazz, 2019-03-12

### *---- "Stop doesn’t work"
Can’t stop the movement with double tap so once it’s going I can’t change between them.
-- DBdc, 2018-01-07

### ****- "Does the job"
It's a little tricky but with enough pinching, tapping the top where the icon bar appears, and sliding down on the screen you can change settings. Direction is changed by catching the movement to a stop and dragging slowly in reverse. It works better with young pediatrics than traditional methods of kinetic assessment and therapy, so worth $5!
-- Functional Neurology, 2016-09-08

### *---- "Doesn't work as described"
My first use of the darned thing and it won't stop on double tap as directed. It will change directions but not stop. Five bucks for a crap app. How about .99? At least I won't feel ripped off for buying an app that doesn't work from the start. Not to mention that it's just rolling bars!  Haven't found color options yet, so that may not work either. Don't buy.
-- mysteryalias, 2016-08-10

### **--- "Glitches"
Cannot change icons or freeze movement once started in current version ! I regret updating !
-- DC2474121050, 2016-01-30

### *---- "Won't load onto my iPad"
Only loads on my iPhone. What a waste of Money
-- Madelle, 2012-06-01

### ***** "New version (1.3.2)"
The freezing issue in fact has been fixed.   I've tried it on both the iPad and iPhone and it consistently has worked very well.
-- UM-SL, 2012-05-29

### ***** "Turbo Drum"
I too had the same problem with Turbo Drum as Camelottt but had she(?) contacted their help desk she would probably have found that her iPad IOS was out of date. Upgrading it to 5.1 was easier said than done and needed a final step of erasing TD then reloading it in order to reset the app directory. Doing this also fixed all the other loaded apps which had stopped working along with the IOS upgrade. Turbo Drum now works as described by the author and is an invaluable aid to neurological disorders.
-- Xlimey, 2012-03-23

### *---- "RARELY WORKS"
I want a refund! Unable to get this app to work properly. Sticks, does not move, continually rebooting. Support info does not alter problems!
-- CAMELOTTT, 2012-03-20

### **--- "Not worth spending money on"
Some Apps have thousands of hours of programming. This App is maybe 2 hours and cost $5!!! Should 1000% be free. Its rudimentary.
-- Prambanan, 2012-02-11

### *---- "WORST APP EVER"
My dr. also suggested this app and you can't get off one page. this should be a free app, not $5s.
-- Ugbugcheese, 2012-02-06

### *---- "Hate this ap"
My Dr asked me to use this ap. I hate it. You can never get to the correct page. I can spend half an hr just trying to get of one page. the MOST AGGRAVATING AP EVER! And I paid for it!! Err.
-- mjchap, 2012-01-23

### *---- "Doesn't work"
I am a neurology resident and have tried this ap but it doesn't work.  Don't waste your money.  The speed was too slow to elicit nystagmus in any of my adult patients or fellow residents.
-- lcmayans, 2011-07-06

### ***** "Dystonia advocate"
This app is amazing. It has become a vital tool in my home therapy program for the treatment of my Dystonia.  It helps me untwisted and cures migraines faster than any medication.  Applied neurology is amazing!  A huge thank you for putting this out there.
-- Gnashgal, 2011-03-31

### ***** "Brilliant!"
I'm going to have to start having my iPhone with me while I see patients now. What a fast and easy way to assess and correct the optokinetic reflex. 
Best though was that I installed it, played with it, emailed with a suggestion and got an email back that my idea was going to be in the next update which is due out soon. 

The other OKN app doesn't have the pediatric 'strip' like Opto Drum does.
-- Sranicki, 2011-03-06
