Adults only
You enter your date of birth when you sign up, and nobody under 18 can sign up or join a team. There are no accounts for minors and no guardian-managed sign-up.
Your local league OS · Adults 18+
Your tennis league, line by line.
Lineups that check the rules, lines the players schedule themselves, live courtside scores, and standings that move only when both captains agree — on iPhone and iPad.

How it works
From invite to standings, one line at a time.
A team match in a local league is an odd number of separate lines, from 3 to 25, so every match has a winner. Hi5Tennis follows each one on its own: who plays it, when and where, the score, and whether both captains have signed off.
Join
Join your team from your captain's invite. Your date of birth confirms you're 18 or over.
Availability
Answer In or Out for each round window in a couple of taps.
Lineup
The captain fills every line. The app checks NTRP, gender and one line per player before anything is published.
Schedule
The players on each line agree a time and court. Time and court lock 24 hours out; players lock 6 hours out.
Score
The captain scores live from the bench, or the players report the result to their captain.
Confirm
The winning side records, the losing captain confirms, and the line counts. Disputes go to the Organizer.
Roles
One account. Three roles.
Everyone starts as a Player. Captains are invited by their Organizer; Organizers subscribe. The app changes colour with the role you're in.

Live courtside scoring
Scored from the bench. Followed by the team.
When a line goes on court, the captain can score it live, point by point, and teammates follow it on their home screen.
- The whole team follows alongThe score scrolls across every teammate's home screen, just above the captain's broadcasts — from the preview to the live score, the final and the celebration.
- One tap per gameAdd a game — or a point in the match tiebreak — with one tap, and undo a point if you tapped the wrong side.
- Sets close themselvesA set ends at six games with a two-game lead, or at seven; a match tiebreak goes to ten.
- Straight to confirmationAt match point the final score goes to the other captain. Once they confirm, the standings update.
18+ & privacy
Built for adult league tennis.
Every Player, Captain and Organizer on Hi5Tennis is 18 or over. Here is what that means, and what happens to your account.
No passwords
Sign in with Apple, with Google, or with a one-time link sent to your email.
Your number stays private
A mobile number is optional. It stays on your profile, is never shown to other players and is never used to sign in.
No public feed
No posts, no photos, nothing to scroll — just your league's lineups, matches and scores.
Money stays off-platform
League fees and team dues are paid outside the app; Hi5Tennis never collects them. Organizer plans are billed by Apple, so we never see your card.
Delete your account in the app
Settings → Data Export / Delete Account. Captains and Organizers hand their role to their co-lead first. The account is deleted at once and can't be restored, and we email you a confirmation. An Organizer subscription is cancelled in your App Store account settings.
Pricing
Play free. Pay only to organize.
Players and Captains never pay. Organizers pick a yearly plan by the size of what they run.

Organizer plans are billed yearly, renew automatically and are cancelled in your App Store account settings; Restore purchases is in the app's Settings. Archived or deleted leagues still count toward the year's allowance. League entry fees and team dues are collected outside the app — Hi5Tennis never collects, holds or splits them.
Less noise. More tennis.
No public feed, no endless content. Just the people, the lines and the decisions that get you back on court.

Good questions, clear answers.
Hi5Tennis is built for local amateur tennis in the United States, in English and Chinese. Anything else? Email support@hi5tennis.com.
Who can use Hi5Tennis?
Adults aged 18 and over. You give your date of birth when you create your profile, and anyone younger can't sign up. There are no accounts for minors.
How do I sign in?
With Apple, with Google, or with a sign-in link we email you — open it on the same phone. There are no passwords, and your phone number is never used to sign in.
How do I become a Captain?
Your Organizer gives you a private invite code for a specific team. Entering it starts the role in that league, and it ends when that league ends. You captain one team per league.
Can I use Hi5Tennis without a league team?
Yes. Start a casual squad of up to 8 hitting partners and call them to a fixture on one to four courts. Hi5Tennis works out how many players it takes — with separate limits for men and women in doubles — and everyone answers in one place, instead of a string of texts.
How does a score reach the standings?
The winning side records the result — from a player's report or entered directly by the captain — and the losing captain confirms it. Only confirmed lines count. A disputed line waits for the Organizer's ruling while the rest keep counting.
Can Captains and Organizers work on a tablet?
Yes. On iPad the app opens a wide landscape workspace for lineups, schedules and disputes. On iPhone it stays in portrait, one task per screen.
Is Hi5Tennis a social network?
No. There's no public feed, no posts, no photos or videos and no group chat — just your league's lineups, matches and scores.
How much does it cost?
Player and Captain are free. Organizer Standard is $39.99 a year for up to 8 leagues with 8 teams each; Advanced is $59.99 a year for up to 16 leagues with 16 teams each. Both are billed yearly through the App Store.
How do I delete my account?
In the app: Settings → Data Export / Delete Account. If you hold a Captain or Organizer role, hand it to your co-lead first. The account is deleted at once and can't be restored; we email you a confirmation. Cancel an Organizer subscription in your App Store account settings.
Is there a web app?
No. Everything runs in the iPhone and iPad app. hi5tennis.com is for downloads, the Privacy Policy and the Terms of Service.
Is there an Android version?
Not yet. Hi5Tennis starts on iPhone and iPad; we'll announce Android here when it's ready.
Your next match starts here.
Hi5Tennis is in final testing. The App Store link appears here the day it launches.
Bring your league into one focused app and spend less time coordinating.
