Tennis partner rotation tracker.

In most recreational groups, the same four people end up partnering together every week. It happens without anyone deciding it — pure inertia. Newer players or weaker players feel quietly excluded. Stronger players never get pushed. Over a season, the group loses cohesion.

You can't fix this without data. And no one wants to build the spreadsheet that tracks it.

Every set you record in Monday Tennis updates a partnership graph behind the scenes. Tap any player to see who they've partnered with most often, who they've faced most often, and their record against every opponent.

• Partner-with-whom matrix surfaces missing combinations
• Per-game scoring means weaker partners still earn individual credit
• Tournament feature lets you define teams explicitly when fairness matters most
• Multi-season history shows year-over-year patterns

Healthy tennis groups stay healthy because new members get absorbed and rotated through. If your group has felt clique-y, or you've noticed the same four names every week, this is the data you need to fix it.
