About SchulteLab

SchulteLab is a free online Schulte table trainer — and, step by step, a small cognitive training platform built around it. The Schulte table is the classic grid exercise for attention and visual search; we keep that core and add what static tables lack: dynamic variants (spinning, blinking, moving targets, size-shift), printable sheets, and local progress tracking.

Most Schulte sites are single static grids with ads. We wanted a trainer that treats practice like practice: timed rounds, personal records, a progress curve, standard-time references, and harder modes once the basics plateau. Everything is bilingual (English / 中文) from day one.

Every feature runs entirely in your browser. Results and history are stored in localStorage on your device — there are no accounts, no uploads, no analytics trackers and no ads SDK in your training data.
