Honesty First
We make no medical claims and no unsupported promises. Our tests are educational tools, clearly labeled as such, always.
Our Story
A Platform for Curious, Active Minds
Recycling Granulator Shredder was developed by the team at Recycling Granulator Shredder Japan as an educational side project — born from a simple idea: that mental exercises can be enjoyable, accessible, and genuinely engaging for adults of all ages, particularly those 55 and over.
We observed that many online brain game platforms were cluttered, made unsupported health claims, or were difficult to navigate on mobile devices. We wanted something different: clean, honest, and easy to use every day.
Our exercises draw from established cognitive research areas — reaction time, working memory, sustained attention, and logical reasoning — presented purely for self-exploration and entertainment, with no medical claims whatsoever.
"Our goal is simple: create a calm, enjoyable space where adults can engage their minds every day — no pressure, no promises, just good mental exercise."
