Lattern: Memory Grid Puzzle
Calm daily focus game
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Lattern is a 60-second daily memory ritual. Calm, precise, and deliberately not brain training.
Each day, a grid lights its cells one by one. After it rests, you light the same path back from memory. The sequence builds as you go: three for the day, a little longer each round. Get it, and your Lattice fills in, a quiet pattern of light that grows day by day.
• One new Lattern every day, the same for everyone
• A gentle build-up, a few tries, never a harsh fail
• The Lattice: your streak, as a calendar of light
• Apple Watch and home-screen widgets
• No accounts, no noise, no pressure
Lattern+ unlocks practice grids, 1,000 training levels, your full history, and removes ads.
Quiet work. Same time tomorrow.
