### 1/5 — It keeps freezing

*2023-08-30*

So I can’t even get into the app.  It just freezes.

### 1/5 — What’s the point?

*2020-08-29*

Anyone explain where’s the test itself??

### 1/5 — Worthless

*2020-01-19*

No instructions, no way to make it do anything. All it does is show and cycle the patterns. You can tap a pattern and instantly get absolutely no response. You can jump up and down on your iPad or phone while running and by doing so, actually get the same result—nothing. You can delete the app and actually get a result—more storage space on your device for things that actually work.

### 3/5 — Believe it or don't ..

*2017-07-20*

It has preset patterns - looks cool, needs a randomizer and more zener patterns and variables .. with a score counter for right and wrong that can be compared over time -like say on a calendar

I think it's neat 👍 and has potential to be really fun and cool
