A Schulte table is the simplest test there is: tap 1 through N, in order, as fast as you can. Schulte Grid PLUS turns that one mechanic into four training modes that build peripheral vision, short-term memory, and sustained attention — fully offline, no account required.
Each mode isolates a different cognitive skill — pick one, or rotate through all four in a session.
Find numbers 1 to N in order, against the clock. The baseline test of visual search speed.
The grid hides after your first tap. Recall the remaining positions from memory alone.
Fix your gaze on a center crosshair and locate targets using only side vision.
Apply a rule — odds only, primes, Fibonacci — and filter the right number out of the noise.
Pick a size, set a rule, and the timer starts the moment you tap. Every session ends with a full performance breakdown.
Speed and a finish time are only part of the picture. Each run is broken down across the dimensions that actually predict improvement.
No login screen, no upload step, no ads tracking your sessions. The grid, the timer, and your history all live on your device.
Core gameplay needs no sign-up and creates no server-side profile. Open the app and start the timer.
Session history and preferences are stored on-device. Clear them anytime from settings or by uninstalling.
We don't sell personal information, and core offline gameplay data isn't shared with third parties.
This is a short summary. Read the full Privacy Policy and Terms of Use for complete details.
Five minutes a day, any grid size, any mode. Schulte Grid PLUS keeps score so you don't have to.
