It Gets Smarter Every Game You Play
Most life counters forget the moment the game ends. Compendium remembers. Every game you track builds a picture of which decks win, who's beating you, and how your pod really plays — so the app gets more useful the more you sit down to play.

Track results over time and see real win rates, matchup patterns, and which of your decks pull their weight.
A life counter built for the table
Life totals, poison, and commander damage for up to 6 players, with the right starting total set automatically for any format.
Every game, logged for you
Each game saves to your history automatically, building the record Compendium learns from. No spreadsheets, no dice.
