This is where you choose a group of players for an event. You can have different groups, like League, Tuesday RR, etc. Tapping a group takes you to the Players screen, where you select players for today and can add new ones. Tap the New Group button to start a new group. Tap the ⋮ next to any group to rename or delete it. Use the ? button on any screen to get help on that screen.

Select the players for the current group and for this event. Tap the New Player line to add a new player anytime. Select their gender and use the ... menu to Rename or Delete this player. Tap any player to select or deselect them for this event.

In the top bar you can choose the rotation mode: Random (everyone mixes partners), Mixed (men and women partners), Team (choose fixed teams for a round robin tournament), MLP Random (randomly choose teams of four and play MLP matches), MLP Team (choose fixed teams of four and play MLP matches). MLP is only available with 8 men and 8 women selected.

Tap the Courts button to assign court numbers to match your actual courts or change the number of courts you're using.

You can still change players once the event has started. Just come back to this screen, rename a player or add another player, and tap Update RR.

Edit the court numbers to match your facility — for example, if you're playing today on courts 5-8, edit the numbers to match. Sometimes you don't have enough courts for a full round robin, but it's worth it to play anyway with a few more byes. The app is smart about this and you can select how many courts you have on this screen. Tap Done when finished.

The app picks the number of rounds that makes the round robin as fair as possible. The first goal is equal byes: everyone sits out the same number of times, and nobody sits out twice in a row.

The normal round robin generated is 7 rounds, normally playable in 2 hours, comfortable for most people. Some sessions have fewer rounds — 10 players on 2 courts, for example, get equal byes after 5 rounds, so we stop there.

Sometimes equal byes take 9 rounds, as with 9 or 18 players. Then the app asks how many rounds you want when you tap Start RR: 9 for equal byes, or 7 or 8 to finish sooner.

If equal byes can't fit in a reasonable session, a few players end up playing one extra game. That extra game doesn't count toward their score, so everyone's total stays comparable.

Within those rounds, the app also gives you a new partner each round until you've played with everyone, mixes up your opponents, moves you between courts, and takes turns on who serves first.

All of the games for the round robin are shown here. After a round is played, enter scores if you want, then tap Round Done to complete that round. Tap the numbers in the round bar to jump to previous or upcoming rounds. The byes for the round are shown at the top, with a Swap button in case someone isn't available — give them the bye and let someone else play the game.

At the bottom of the games is an adjustable timer if you need to limit the length of your rounds.

In the top bar you can switch between Rounds and Stats to track wins and losses and total points. If a game goes over 11, it's automatically adjusted down to 11 so that all the scores are compared fairly.

If another player shows up, or someone has to leave, go back to the Players screen and add or remove players, then tap Update RR. Rounds already completed won't change — the upcoming rounds will be updated with the new players. The Cancel button cancels the current round robin so you can start another one.
