Tennis club nights, ladders and knockouts, without the spreadsheet.
Mix-ins, club championships, singles ladders and box leagues, run from one app.
Most tennis clubs run the same handful of things: a weekly social doubles mix-in, a singles ladder somebody keeps in a spreadsheet, a box league that lives on the noticeboard, and the club championships every summer. Rallio runs all of them, and players join, play and report scores from their phone.

What you can run
Tennis at your club, all in one app.
Social doubles mix-ins
Players sign up for the club night and Rallio draws balanced doubles, mixed where the numbers allow, with fresh partners every set. Reserves step in automatically when someone drops out.
How it worksSingles and doubles ladders
A tennis ladder that keeps itself up to date. Players challenge anyone in range, agree a date, and the ranking moves when the score is confirmed.
How it worksBox leagues
Small singles boxes by level, a playing window of a few weeks, and live standings. At the end of each window the top players move up and the bottom players move down.
How it worksClub championships
Seeded knockout draws for singles, doubles and mixed, with optional handicaps (−15, −30, −40) set from players’ levels, and a live board for the clubhouse.
How it worksFind a hit
Members post a game for a time that suits them and pick who joins, so a Saturday hit doesn’t depend on who reads the group chat first.
How it worksLevels and ratings
World Tennis Number, UTR or your club colours
Start from the Red, Orange and Green bands many clubs already use, or let players add their World Tennis Number or UTR. Rallio converts them to one club scale so draws and seedings start fair.
Tennis questions
No. Rallio doesn’t take court bookings or membership payments, so you keep ClubSpark or whatever you book with today. Add your booking link and players see a “Book a court” button when they arrange a game.
Rallio also runs padel, pickleball and squash.
