About RallyMixer

RallyMixer is a tool for badminton players who run casual pickup sessions and want fair, balanced doubles rotations — without the mental overhead of working it out on the spot. It's designed for groups playing doubles on a single available court.

The problem it solves

Anyone who organises a regular pickup game knows the friction: who plays with who, who's been sitting out too long, which pairs keep getting an unfair advantage. RallyMixer generates rotation schedules that balance partner variety and rest time automatically, so you can focus on playing.

Features

• Generate up to 60 rounds for 4–20 players
• Fair rotation algorithm — minimises repeat pairings and uneven rest
• Live room sharing so everyone at the court sees the same schedule in real time
• In-app scorekeeping with game-point detection
• Works without internet after your first visit
• No sign-up required

Who built this

RallyMixer was built by badminton players who kept running the same problem at every pickup session — too much time figuring out rotations, not enough time playing. So we built the tool we wished we'd had.
