In-app scorekeeping
RallyMixer tracks scores, serving order, court positions, and game point — so the person keeping score can follow the game instead of managing it.
The round card
Each game is represented by a round card. The active round is the one expanded on screen (on desktop, it's shown in the right panel; on mobile, it's highlighted in the list with a pulsing green dot in the Rounds overview).
The card contains:
- The round number and which player is assigned as scorekeeper
- The two teams with player names
- A visual court showing who stands where
- Score controls for each team
- Serving indicator
- A score record of all points in sequence
You don't need to use all of it. At minimum, just tap + on the serving team after each rally — the rest is optional.
Adding and subtracting points
Tap the large + button above each team's score to add a point. Tap – to subtract one if you tapped incorrectly. You can also tap directly into the score field and type a number if you've fallen behind and need to catch up quickly.
Tip: If you're using the Live Room, score changes sync to all viewers within a second or two. There's no need to confirm — just tap and the room updates.
Setting the first serve
Before a round starts, the card prompts you to set which team serves first. Tap the team name or either player button in the service panel to record the first server. This is optional — if you skip it, serve tracking is disabled for that round.
Once the first server is set, RallyMixer tracks serve changes automatically. In rally-point badminton, the serve passes to the other team whenever they win a rally. The app follows this rule and updates the serving indicator on every point tap.
Court positions
The court visual shows which player stands on which half and side. Tap the swap button (⇅) inside a team's half to switch the two players within that team. Tap the centre swap button (⇄) to switch which team plays which end of the court.
These controls are mainly useful at the start of a game when teams walk on and need to know where to stand, or after a rubber game when ends are switched.
Court position changes are local — they update your view and sync to Live Room viewers, but don't affect scoring or the rotation schedule.
Game point detection
When a team's score reaches one point below the target score, the game-point banner appears at the bottom of the card. The banner shows which team is on game point. This is a visual cue only — it doesn't stop scoring or require any action.
When a team reaches the target score, the round is automatically marked complete. The card compacts in the list, the score is frozen, and the next round becomes active.
If both teams reach a score that requires a deuce rule (for example, 20-all when playing to 21), the app does not currently enforce a deuce extension — it marks complete when the first team hits the target. If your group plays deuce, continue tapping until the deciding point and mark complete manually. For a full breakdown of how scoring and deuce work, see the badminton doubles rules guide.
Marking rounds complete manually
If you're not using the app for scorekeeping but just want to track which rounds have been played, tap Mark complete at the bottom of the round card. This compacts the card and advances the session to the next round without requiring a target score to be reached.
You can also tap Reset score to clear both scores back to zero without marking the round complete — useful if you started scoring in the wrong round or need a fresh start mid-game.
Score record
The score record (shown collapsed below the scoring controls) logs every point in the order it was tapped — Team 1 or Team 2, with a running tally. This is useful if there's a dispute about the score or serving order mid-game. Expand it to see the full rally log.
The Rounds overview
The Rounds overview shows the full session at a glance — every round, both teams, the final score if the round is complete, and a coloured status indicator:
- Green dot (pulsing): the active round currently in play
- Green check: round complete with a recorded score
- Grey dash: upcoming round, not yet started
On desktop, tap the Rounds overview button in the panel header to open it as an overlay. On mobile, it appears inline above the round cards — scroll up to see it, or tap the sticky Rounds overview → entry bar to jump to it.
Scorekeeper column: The overview table also shows which player is assigned as scorekeeper for each round. This is the player whose name appears in the round card header — a signal to that person to watch the score for that game. On mobile, this column is hidden to save space.
