Tournament Manager is a free Android app developed by Alexander A. Rogachev. It is a lifestyle app designed to create and manage competitions and tournaments for your friends and family with ease. It is primarily aimed at match/game based tournaments like Chess, Go, Badminton, MTG, and others.

One of the main features of the app is that it can handle tournaments for up to 32 players. It also supports different types of events, including Single Elimination, Swiss, Round Robin, Double Round Robin, and Double Elimination. The app can automatically pair players for rounds, and it has a smart byes system to handle odd numbers of players. Moreover, the app supports players leaving tournaments.

It is important to note that this app works offline-only and stores all data locally on your device. Currently, there are no cloud storage or data synchronization options available.
