### 1/5 — didn’t work??

*2026-07-01*

it wasn’t working when i was using it!! other than that its a nice idea

### 4/5 — Great Brain Game but…

*2026-04-09*

I thought there used to be more colours to unlock. I’d be happy to pay for ad free but when I click on the main menu an ad pops up. I’m not willing to wait through the ad to find out what else there is to it.

### 2/5 — Annoyed with commercials

*2025-06-18*

Love this app but each time I restart for my next attempt I am forced to watch an ad for another game I have no interest in any idea how to stop that ?

### 1/5 — Crashes all the time

*2025-06-05*

Great game, but basically crashes nonstop. Please fix it so it’s functional!

### 1/5 — Funktioniert nicht richtig.

*2023-07-07*

Auch wenn man sich sehr viel Zeit lässt und genau hinschaut und garantiert keinen Fehler macht, so ist oftmals die Bewertung falsch.

### 5/5 — Still better than 99% mobile games

*2021-10-26*

Best way to wake up

### 1/5 — Not working

*2021-07-21*

I can not get this program to work. It changes it’s mind about weather it is pursuing colour or word.
Please fix, I need this app.
Thanks 
Katherine

### 2/5 — No sound or support to resolve issue

*2021-05-01*

I’ve gotten used to having sound with the app but now when using on my iPad there isn’t any. The app on my iPhone works fine but the screen is a bit small for me. I’ve tried reaching out to the support team to resolve this issue but I haven’t heard anything back. Also, it’d be nice if there were a paid version to not have to deal with the pop-up ads after each game. The ads are not overly intrusive but I still find them annoying. Despite recent issues, it’s a decent app that I enjoy using.

### 3/5 — Great app when working properly

*2020-03-07*

I tried your app support link, but it doesn’t work so I’m contacting you here. I have the unlocked expert mode, but for some reason now when using your app after every time I do a cycle I get a pop up ad when I press restart. Even worse than the new ads, the ads freeze on the screen and I can’t X out of it and have to manually close/clear the app to start again. Please help!

**Developer response:** Hello Unhappy Strooper! The support website is up and running without any issue. Please contact me via the form so that I can troubleshoot the situation. -> https://stroopeffectapp.com

### 2/5 — Crashes on open

*2019-12-24*

Was stable until 6 months ago. Unusable.

**Developer response:** Hello Vinman54! Would you mind sharing your experience in detail?
