Mind Palace - Memory Train

Mind Palace is an engineered implementation of the Method of Loci, the spatial-memory technique used by world memory champions. It converts arbitrary text into structured spatial cues and drives you through a measurable two-phase training loop. ENGINE - Imagery layer: each input is mapped to (icon, palette hue, scene caption, keyword set) by an on-device deterministic mapper, no LLM, no network - Three theme-coherent route layouts: Castle, Forest, Space Station, each with 8 landmark cue sets - Stable encoding: the same input produces the same cue, supporting repeated rehearsal TRAINING PROTOCOL - Phase 1 Memorize: walk the route, observe the visual encoding for each peg - Phase 2 Recall: blind input on each peg, accuracy graded per peg - Score = accuracy x 0.7 + speed x 0.3, baselined at 180 s - Tournament mode persists scores to a local leaderboard for longitudinal tracking PRIVACY AND FOOTPRINT - 100% on-device. No accounts, no analytics, no remote endpoints, no third-party SDKs - All palaces and tournament records persist in local UserDefaults - No background activity. App is dormant when closed. USE CASES - Vocabulary acquisition (L2 learning, GRE/IELTS) - Formula and definition retention (medical, engineering) - Speech and pitch rehearsal (sequential cue chains) - Procedural lists (checklists, routines) REQUIREMENTS - iPhone, iOS 17 or later - No connectivity required at any point Train with intent. Measure with rigor. Mind Palace ships the algorithm of antiquity in a clean, modern, and verifiable form.
