Train your brain by playing cool memory games. Remember the scene and answer the question. But it is not as simple as it may seem. You only have a few seconds to remember everything you see on the screen. Every time you choose the wrong option, the question will be changed. And rest assured, the questions will be very unpredictable. The locations will vary from level to level, and in addition, the scenes are built with beautiful graphics and lots of great animation. Have fun and test your memory!

【Not just a game, but an experiment in evolution】 Inspired by the famous "Ayumu Project" at Kyoto University. A chimpanzee named Ayumu demonstrated an eidetic memory capability that leaves most humans in the dust. It makes us wonder: along the millions of years of evolution, as we gained language and logic, did we lose some primal, powerful instincts? This app brings that legendary laboratory challenge to your phone. 【The Core Challenge】 Numbers flash on the screen and vanish in the blink of an eye. You must tap them in the correct order relying solely on your instantaneous visual afterimage. Eidetic (0.5s): Think like Ayumu. Challenge the limits of humanity. Average (2.0s): A starting point for most sapiens. Rote (10.0s): Take your time. For those who admit defeat (jk). 【Ultimate Experience】 To replicate the purest reaction test, we've optimized this app to the millisecond: Zero-Latency Audio: Built with iOS SystemSound API for instant feedback the moment you touch. Fluid Interaction: No superfluous animations to drag down your reaction speed. Minimalist Aesthetic: High-contrast black and white design to keep you hyper-focused. 【Secret Features】 Too hard or too easy? Try a LONG PRESS on the start button. Want to know the story? Try SHAKING your phone. This might be the simplest game on your phone, yet the hardest challenge you'll ever face. Can you reclaim your primal power?

Verdict
The clearest difference is ads: MDonkey at none against Brain Tests's shown. MDonkey also leads on update cadence (daily vs every 8 months). Brain Tests's advantage is iOS requirement (12.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.
