## What is Munin?

The chess trainer that remembers what you miss: offline, no account, pay once.

Munin is a tactics coach that works anywhere: on a plane, on the train, in a cabin with no signal. Every puzzle, the engine and all your progress live on your device.

WORKS OFFLINE
• 275,000 selected puzzles from beginner to master, built into the app
• No internet needed to train, review or play on against the engine
• Flight sessions of 10, 20 or 30 minutes

REMEMBERS WHAT YOU MISSED
• Every missed puzzle comes back with spaced repetition: after 10 minutes, then 1, 3, 8 and 21 days
• Cycle mode: solve the same set again and again, faster and more accurate each round
• 72 themes, from forks and pins to back-rank mates, with your weak themes marked
• Openings: the tactics of the Sicilian, the French, the Caro-Kann and 34 more

LEARNS FROM YOUR OWN GAMES
• Mistake book: import your public games from Lichess or Chess.com by username
• Your games are analysed on your device by the built-in Arasan engine, and the moves that cost you turn into puzzles

FIND YOUR LEVEL
• A short placement test gives you a rating and a rank, from Pawn to King
• Glicko-2 rating that adjusts as you train
• Stats: rating graph, accuracy per theme, cycle rounds and streak

PLAY IT OUT
• After a puzzle, play the position on against the engine at the strength you choose
• Any checkmate counts as a solution, even if it isn't the one in the book

FAIR AND QUIET
• Try everything free for 3 days. Nothing is charged when the trial ends.
• After that, free: 10 puzzles a day, the daily puzzle and your reviews included.
• Munin Full Access unlocks unlimited puzzles, theme drills, all 37 openings, flight sessions, cycles and the mistake book. One payment, no subscription.
• No account, no ads, no tracking, no hint coins, no lives
• Your training data stays on your device

Puzzles come from the Lichess puzzle database (CC0). Munin is not affiliated with Lichess or Chess.com.
