Check your ability to focus your mind despite interference! We invite you to test yourself with the so-called Stroop Test adopted for iPad. Stroop Effect app is a fun experiment in neuropsychology. Find out how your brain is playing tricks on you. See if you can train your brain to ignore interference. There are 3 variations: - No interference - Light interference - Heavy interference In each version you must tap the color of the word and NOT the color described by it. For example: if the word Blue is printed in red ink - you should choose Red as the answer. You will get one point for each correct answer and minus one point for each incorrect answer. You have 30 seconds in each test. Do your best! Features: - develop your memory and concentration - train your ability to focus - compare results with other players in the Game Center - great fun for a company of friends Why? The words themselves have a strong influence on your ability to say the color. The interference between the different information (what the words say and the color of the words) your brain receives causes a problem. There are two theories that may explain the Stroop effect: Speed of Processing Theory: the interference occurs because words are read faster than colors are named. Selective Attention Theory: the interference occurs because naming colors requires more attention than reading words. The interference effect suggests you're not always in complete control of what you pay attention to!

Verdict
The clearest difference is price: CBS at Free against The Stroop Effect's $0.99. CBS also leads on rating (4.8 vs 4.0) and update cadence (fortnightly vs every 5 months). The Stroop Effect's advantage is ads (none vs shown) and review sentiment (67% vs 36%). On in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
CBS is free to download; The Stroop Effect costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
CBS holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: CBS has 71K ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 67% of The Stroop Effect's written reviews are positive against 36% of CBS's, so the app with the better star average is not the one people write more warmly about.
The Stroop Effect ships an update every 5 months, CBS fortnightly. The most recent releases landed on October 18, 2026 and October 19, 2026 respectively.
