Mars LogBook

Mars LogBook is a free, non-commercial companion and personal game journal for Terraforming Mars players. It helps you prepare a game, calculate final scores, save results, and gradually build a personal history of your expeditions to Mars. SAVE YOUR GAMES Record players, corporations, preludes, boards, expansions, colonies, milestones, awards, generations, and final results. Every completed game becomes a permanent entry in your personal logbook. CALCULATE SCORES Mars LogBook helps with final scoring across the main scoring categories, milestones, and awards, determines player rankings, and handles tied results correctly. FOLLOW YOUR HISTORY Your personal logbook shows games played, victories, win rate, average and best scores, game preferences, personal records, and recent expeditions. HOST MODE Mars LogBook can also accompany the game itself. Track player order, generations, turns and passes, use individual player timers, and get assistance during drafting. For competitive games, an optional Sports Mode adds time and generation limits while keeping the sports result separate from the classic Terraforming Mars score. YOUR LOGBOOK STAYS YOURS Your game history and profile are stored locally on your device. You can create a backup of your journal and restore it later. The interface is available in English and Russian. Mars LogBook started as an app I built for my own gaming group and is shared as a free project with other Terraforming Mars fans. Mars LogBook is an unofficial fan-made companion app and is not a digital version of the board game.
