Set up once.
Run it by text.
You do 5 minutes of setup on the web. Everything after that lives in your messages.
Create your group
Log in with your phone (no password), name your group, add a few players. Or just text "create a group called Friday Night Tennis" — that works too.
Text the AI to schedule
"Doubles this Friday 6pm at Riverside, invite everyone." It creates the match and texts the whole group. Change plans anytime — "move it to 7pm", "cancel Friday".
Watch it fill
You get live updates — "Bill's IN, 3/8 confirmed." Full match? Waitlist handles it. Enough players? Text "set the lineup" for balanced teams.
Get the invite
A text lands: "Tennis Friday 6pm at Riverside. Reply YES to play, NO to pass." No app, no login, works on any phone.
Reply naturally
"I'm in" / "can't make it" / "waitlist me." Ask "who's coming?" or "when do we play?" anytime.
Play & brag
Show up to your court and partner. After: text "we won 6-4 6-2" to log it, and "what's my record?" to check your stats.
