User Reviews
Should have a recording feature
I like it!
My vision therapist recommended this app to help with eye stretches. It’s good, but I wish I could change the direction the bars move. I have to do this exercise with a patch on because my eyes don’t track together. So I’d like it if the bars could travel left or right and up or down.
Would have been nice to choose some things like smooth pursuit, saccades, vor
Dont want this app
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
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.
Useless without
Great app! Has corrected my issue with left hand shaking.
Useless to me without instructions on how to use it
