The ancient art of memory, rebuilt for your pocket. The Method of Loci — used by Cicero, Sherlock Holmes, and every World Memory Champion — works by placing vivid mental images inside familiar locations you can walk through in your mind. Pocket Palace is the only app built around this technique from the ground up. BUILD YOUR PALACES Create memory palaces from real places you know — your childhood home, a school, your daily commute. Add rooms as stops on your mental walk. Plant loci — the exact spots where memory images live. Every palace you build becomes a permanent storage location your brain never forgets. SPACED REPETITION TRACKER Memory doesn't work without review. Pocket Palace's built-in Tracker runs a scientifically-grounded spaced repetition schedule: review on Day 1, then +3 days, +7 days, +30 days, +90 days, and +270 days. Self-report each review honestly. Miss a date and the sequence resets — that accountability is the whole system. BREATHING BREAK Memory consolidates best during rest. The built-in Breathing Break guides you through the 4-7-8 technique — a 60-second session between study sessions. Complete a session to permanently unlock 5 additional palace slots. One session every 48 hours. EARN YOUR RENOWN Every review you complete earns you a stage. Progress from Initiate to Scholar to Architect to Mnemonist to Grand Master. Your Renown reflects genuine, consistent practice — not just how many palaces you've created. THE METHOD WIKI New to memory palaces? The Method tab is a complete guide: how to choose a palace, how to place loci, how to create vivid memory images, and how to use spaced repetition effectively. Everything you need to go from beginner to serious practitioner. PREMIUM: PAO & PEG SYSTEM Serious memory athletes use the Person-Action-Object (PAO) system to encode numbers. Assign a memorable Person, vivid Action, and distinctive Object to every number 00 to 99. Chain them into scenes. Place the scenes in your palace. A 10-digit number becomes a 3-scene story you'll never forget. The Major/Peg System reference teaches you how to convert numbers into consonant sounds and build words — the foundation every great PAO list is built on. WHAT'S FREE 5 memory palaces, unlimited rooms and loci Spaced repetition Tracker (3 palace slots) Complete Method wiki Renown progression system Breathing Break with palace slot rewards CSV data export 10 practice sessions per day POCKET PALACE PREMIUM Three ways to unlock everything: $0.99/month — try it with no commitment, cancel anytime $5.99/year — best value, save 50% vs monthly $14.99 one time — pay once, own forever Premium includes: Unlimited palaces and Tracker slots PAO List — build your global 00–99 Person, Action, Object system Major/Peg System reference and multi-digit encoding guide Full Metrics History with review charts Instant Breathing Break access from the home screen Existing $2.99 purchasers are automatically recognized as lifetime members.
