Prefrontal Lab

Read full description

Prefrontal Lab is a collection of short training games for iPhone. Each round takes about a minute. Open it, play one, put it away. Every feature is open to every player, with no subscription. SIX GAMES · Schulte Grid — Tap numbers from 1 to 25 in order. · Stroop Test — Ignore the word meaning. Choose its actual color. · N-Back Memory — Decide whether the number matches the one 1 step ago. · SET Logic — Find 3 cards whose color and shape are all same or all different. · Neuron Counting — Count every matching target shape, then submit the number. · Code Logic — Use four clues to find a three-digit code with no repeated digits. ADVANCED AND ENDLESS Besides Basic, every game has a harder Advanced mode and an untimed Endless mode you play until you choose to stop. What Advanced changes: · Schulte Grid — tapped cells leave no mark · Stroop Test — the color swatch is removed; you choose the written color name instead · N-Back Memory — 2-Back, matching two steps back · SET Logic — adds fill level, which must also be all same or all different · Neuron Counting — more similar, moving distractions · Code Logic — four-digit codes with no repeated digits TWENTY-TWO SCHULTE BOARDS Schulte Grid has a page of its own. Pick a size — 3×3, 4×4, 5×5 or 6×6 — then a way to play it: forward, reverse, evens first, odds first, or blind. There is also a letters board, A through Y, and an Endless mode with no clock. Every board keeps its own best, and the result screen offers the next one to try. YOUR TEXT SIZE Set it in Settings ▸ Display & Brightness ▸ Text Size and the app follows, with no restart. DAILY CHALLENGE One fixed task per day, the same for everyone. Visual Lightning, Reverse Radar, Color Override, Memory Loop, Logic Calibration, Neural Storm, Letter Maze and Expanded Grid rotate through, each finished in 60 to 120 seconds. Completing it checks in the day and builds your streak. COGNITIVE ARENA A continuous mixed run of Schulte Grid, Stroop, quick SET, N-Back and Neuron Counting, in Basic or Advanced, tracking your personal best. ABOUT YOUR DATA Prefrontal Lab collects nothing. Your training records, level progress, daily check-ins, language and sound settings are stored only on your own iPhone. Nothing is uploaded, and there is no account to create. There are no ads. Privacy Policy: https://prefrontal-lab.com/privacy
