About

Lucidmi

Your brain has an incredible short-term memory — most people never train it. Lucidmi is a five-minute-a-day brain training game built around real working-memory research. Every round shows you something, then asks you to rebuild it from memory by dragging pieces back into place, exactly as you saw them. FIVE WAYS TO TRAIN • Spot the Difference — catch what quietly moved • Breadcrumb — retrace a path from memory • Numerosity — track shifting counts under pressure • Spatial Recall — rebuild a whole scene from scratch • Mirror & Rotate — recall through a twist CLIMB LUCIDMI'S ASCENT Every day brings one new challenge across all five games. Clear it and you climb — Rookie, Sharp, Focused, Genius, Mastermind — over a 25-level ascent modelled on the real elevation of the world's tallest mountain. Watch your route light up on a live elevation chart as the summit gets closer. BUILD A STREAK Come back daily to keep your streak alive and work toward a set of achievements spanning speed, accuracy, consistency, and rank. TRAIN RECALL, NOT JUST REFLEXES A quick daily check also tests what you remember from your last session — not just the round in front of you. SYNCS EVERYWHERE Progress, stats, and streaks sync automatically across every iPhone and iPad signed into your iCloud account. FREE TO PLAY All five games and the full 25-level ascent are free, forever. Lucidmi's Ascent+ is entirely optional: unlock a weekly bonus climb, deeper stats, and goal insights for £0.99/month or £7.99/year. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed anytime in your Apple ID account settings. Payment is charged to your Apple ID at confirmation of purchase.
