My opinion

Its the best game ever kinda hard though

Disappointing

Click on the correct/ck mark and it doesn’t register and counts it wrong. Removing the game. I want a game that you can actually play and be challenged correctly!

Sooo fun

It's really good

Redownloaded

The app does what it needs to do

Gut

Nach wie vor top: Einfach gehalten und aufs Notwendigste beschränkt, ohne den ganze Schnickschnack. Fünf Sterne für eine regelbare Lautstärke, derzeit gibt es nur an oder aus.

FAQ

What is the One Brain app?

One Brain is a mobile game inspired by the Stroop effect, a psychological test. It challenges your brain to process conflicting visual information, such as identifying the color of a word when the word itself spells a different color, or verifying math equations.

What are the game modes available?

The app features three distinct game modes: 'Colors,' where you determine if the word's text color matches the word itself; 'Arrows,' testing if an arrow points in the direction it states; and 'Numbers,' requiring you to verify if a math equation is true or false.

Is One Brain free to play?

Yes, the app is free to download and play. It does include advertisements and offers in-app purchases, which may provide benefits or remove ads.

What is the main goal of the game?

The primary goal is to score as high as possible by correctly answering the challenges presented in each game mode before time runs out. It's designed to test your cognitive speed and accuracy under pressure.

Who is this app designed for?

This app is designed for anyone interested in testing their cognitive abilities, improving reaction time, and engaging in a fun, challenging brain training exercise. It's particularly appealing to those interested in psychology and cognitive science.
