OptoDrum

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.

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.

This app does not work as described. I want a refund please!

Can’t stop the movement with double tap so once it’s going I can’t change between them.

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!

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.

Cannot change icons or freeze movement once started in current version ! I regret updating !

Only loads on my iPhone. What a waste of Money

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.

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 contacted their help desk she would probably have found that her iPad IOS was out of date.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.
