RallyMixer Features
Fair rotation scheduling, real-time session sync to every phone at the court, and in-app scorekeeping — all in one free tool, no install required.
Core features
Fair rotation algorithm
Generates a full session schedule that distributes rest rounds evenly, rotates partners across every round, and spreads opponent matchups — for any group of 4 to 20 players.
How it works →Live Room
The only badminton pickup tool with real-time session sync. Everyone at the court sees the same rounds and live scores on their own phone — no group chat, no passing your phone around, no install.
