Assistant Lost Cities is a free Android app developed by Thomas Valloo that serves as the perfect companion app for the popular board game Lost Cities from Reiner Knizia. This app is designed to make scoring after each round simple and easy, so you can focus on enjoying the game without worrying about keeping track of points.

The app is not a game in itself and requires the actual board game to play. However, it provides a hassle-free experience by eliminating the need for pen and paper or any other scoring mechanism. Moreover, the app is completely ad-free, ensuring an uninterrupted gaming experience for the players.
