## Description

Drill your repertoire move-by-move, spaced-practice the lines you keep forgetting, and watch your stats shore up the holes in your opening prep.

Lattice is a focused chess opening trainer for serious players who want a clean way to study, drill, and remember their repertoire.

A curated library of named openings, a board you can step through move by move, a spaced-practice drill, and a stats view that shows where your memory leaks — all in one quiet app. No ads, no accounts, no nonsense.

KEY FEATURES
• Library of classical and modern openings, tagged by ECO code and side
• Filter by White, Black, or universal lines; sort by popularity
• Interactive board with move-by-move stepper for every line
• Practice drill: blind-recall the next move from a position you have studied
• Stats screen that surfaces accuracy, streaks, and weak openings
• Brass-and-wood visual style designed to feel like a study desk, not a casino

DESIGNED FOR REAL STUDY
Whether you are building a junior repertoire, prepping for a tournament, or just trying to stop blundering the first ten moves in blitz, Lattice helps you turn opening theory into actual memory.

PRIVACY
No tracking. No accounts. No network calls. Your repertoire lives on your device.
