In simple words: When psychologists and cognitive scientists want to measure how quickly human minds react to things (like flashes of light or word tests), people traditionally have to go into a university lab and sit in front of specialized laboratory computers. Testing online with regular phones or laptops usually has lots of lag and freezes. RelyMind is an innovative web platform that eliminates that lag, letting anyone participate in brain and reaction-time experiments directly from their phone or laptop with laboratory-level precision, zero software downloads, and 100% user privacy.
