Lattern: Memory Grid Puzzle

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.

Three rounds. Sixty seconds. One quiet streak.

What you get:
- 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
- Calm stats: your span, your best, your steady days
- A home-screen widget
- No accounts, no noise, no pressure

A quiet memory puzzle, not a race. No timers counting down, no leaderboards, no streaks to lose. The grid lights a sequence; you memorize the pattern and light it back. Spatial memory, focus, and concentration, one calm round at a time.

If you like Simon Says-style sequence memory, Corsi-style spatial recall, daily puzzle habits, or simply a gentle grid puzzle to end the day, Lattern is built for that single calm minute.

Lattern+ unlocks practice grids, 1,000 training levels, your full history, and removes ads.

Quiet work. Same time tomorrow.
