## What is Lattern?

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.

## Version history (last 5 releases)

### 1.8 — 2026-07-06

Small behind-the-scenes improvements to keep Lattern running smoothly. Same quiet daily puzzle.

### 1.7 — 2026-06-27

A gentle new opening when you light your first Lattern of the day. Same quiet puzzle.

### 1.6 — 2026-06-22

Small behind-the-scenes improvements to keep Lattern running smoothly. Same quiet daily puzzle.

### 1.5 — 2026-06-18

A steadier hint. Use one and the cells light up numbered in order and stay on the grid, so you can follow and tap the whole solution at your own pace. Also fixed a hint that could stall after a rewarded ad.

### 1.4 — 2026-06-17

Sound, if you like it. The grid now plays soft, warm tones as the sequence lights and as you tap it back, with a gentle resolve when a Lattern is lit. Calm by design, it respects your mute switch, and you can toggle it in Settings.
