### 3/5 — Terrific

*2016-11-15*

I'm your first review😊 hoping this will help my side vision because mines bad. Little hard to do this right now, but hopefully this app improves it.

### 4/5 — What?? No instructions

*2018-09-24*

I shouldn’t have to come to the App Store to get the instructions for the app.  It would be helpful if you included them in the app itself.  I deleted it because I couldn’t do it, gave up.

### 4/5 — Cool app

*2017-08-23*

Maybe some times to aim for to unlock the next stage could be cool

### 4/5 — Cool

Very cool app! I enjoy challenging myself. A little addicting... even if they are just "tiny" 0's!!!

### 5/5 — 頭良くなったん？

*2024-02-17*

正直信じていいか分かんない

### 5/5 — Great brain train

Great for quick recognition and memory.

### 5/5 — Nice distraction
