Tennis tournament organiser
Club tennis
that runs itself
Pick a format, add the players, and DTennis builds every round, records every score and crowns a champion. Real tennis scoring, singles or doubles, from a Tuesday social to a full interclub tie.
No spreadsheet, no whiteboard, no group chat arguing over who sits out next.
- No account, no sign up
- Works fully offline
- No tracking
- Free to start
Eleven formats
The formats the sport actually uses
Draws, rotations, interclub ties, ladders and squad battles. The engine handles courts, rounds, byes and seeding for every one of them. You enter scores.
Single Elimination
The classic knockout draw. Add a consolation bracket and a first round loss is not your last match.
Round Robin
Everybody plays everybody once, and the table decides it. Ranked by USTA Regulation II.B.6, not by an invented tiebreak.
Pools + Playoff
Two to four pools feed a knockout, one or two through from each. Snake seeded, byes to the top pool winners.
Compass Draw
Nobody goes home early. A loss moves you sideways, not out.
Rotating Partner Doubles
Enter as an individual. Partner with and play against everybody, one leaderboard at the end.
Fixed Partner Round Robin
Pick a partner and keep them all day.
Team Competition
Two clubs, a fixed slate of singles and doubles lines. USTA 3, 4 and 5 line ties, Davis Cup and Team Tennis.
Team Rotating Doubles
Two clubs, pairs re-formed every round. The honest club night.
King of the Court
Win and climb toward Court 1. Lose and drop a court.
Team King of the Court
The same ladder, climbed by fixed pairs.
Squad Battle
Squad against squad, with playing levels choosing the lineups.
Singles, graded, mixed: options, not extra formats. Run any rotation as singles. Seed the next round off the live table instead of the circle. Hold two men and two women to a court. Each is a switch on the format you already picked, so the list stays short and the rules stay honest.
Fair by construction
Rotations that stay fair without you policing them
Everyone gets a turn
Play with and against everyone across the session. Court time evens out and sit outs are spread on purpose, not left to luck.
Pair off the live table
Turn on grading and each round is drawn from the current standings, so the leaders meet the leaders and the matches stay close.
Draws that seed properly
A knockout hands byes to the top seeds and names every stage. Pools snake seed into the playoff. Nothing is stored that can go stale: the bracket is rebuilt from results every time.
Real tennis scoring
Scores that follow
the rulebook
Not a generic point counter with a tennis logo. Four presets, each a named format with its own target, its win by two rule and its ceiling.
- 4
Fast4
First to four games, no ad, tiebreak at three all.
- 6
Standard Set
Six games, two clear, 7-6 tiebreak.
- 8
Pro Set
The eight game set used for club and junior play.
- 10
Match Tiebreak
The ten point breaker that replaces a deciding set.
Set the match format once and every surface says the same sentence: best of three, standard set, no ad. Record the match as 2-1 if that is all anyone knows, or write it out set by set as 6-4 7-6 and the app keeps the two in step. A match tiebreak counts as one set and one game, exactly as the regulation says.
Features
Everything the organiser is juggling, in one app
Live scoring
Tap in a score, the winner highlights, the next round unlocks. Built to be used courtside with one hand.
Leaderboard
Wins, point difference and fair compensation for anyone who played fewer matches. Medals on the podium when it is done.
Per set scores
Enter 6-4 7-6 when you have it, 2-1 when you do not. The breakdown never disagrees with the match score.
Player profiles
Career stats across every tournament: win rate, recent form, streaks, best partners, head to head records and 13 earnable badges.
Playing time check
Games played, sit outs taken and longest run on court per player, with a plain verdict on whether the rotation is balanced.
Bench
Park someone who is sitting out a while without withdrawing them. One tap brings back whoever has waited longest.
TV mode
Put the board on the club screen. Mirror the phone, or drive an attached display independently and keep using the app.
Court mode
Hand a device to each court and let them score their own matches. Everything lands in one table.
Session clock
Tell it when the courts are yours until and it fits the rounds to the booking.
Leagues
Combine standings across every event, so a season adds up instead of scattering.
Split costs
Divide the court fee and track who has paid, without a second app.
Share the result
A full text summary, or a branded result card with podium and standings, sized for WhatsApp and Instagram.

Privacy policy
Your tournaments stay on your phone
DTennis has no account, no sign up and no tracking. Everything you create lives on your device. This page explains exactly what that means, and the few things the app does connect to.
Last updated: 26 August 2026
What stays on your device
Every tournament, player, score, league, cost split and setting you create is stored only on the phone or tablet you created it on. None of it is uploaded to us, and we have no way to read it.
Backups are files you control. When you export one it is saved or shared wherever you choose, and nothing about that copy comes back to us. Uninstalling DTennis removes all of its data from your device.
What the app connects to
DTennis works fully offline, and a handful of features do talk to a server. None of them carry your tournament data. In full:
- Checking for a new version. The app asks whether a newer release exists. The request says nothing about you.
- Delivering app updates. Improvements can arrive without a store update by downloading new app files. The usage reporting built into that component is switched off.
- Unlocking DTennis Pro. Apple or Google takes the payment and we never see your card. To confirm the purchase is genuine and to restore it on a new phone, the app sends the store's purchase receipt identifier to our server. That identifier refers to the purchase, not to you: it carries no name, email or device identifier, and it is not linked to anything else.
- Google Drive backup, if you connect it. Drive backup is off until you sign in to it yourself, and the app asks Google for the narrowest permission there is: access to the files this app created, and nothing else in your Drive. The backup file goes from your device to your Drive. It does not pass through us, and the sign in tokens are kept in their own place on the device so they can never travel inside a backup file you share.
- Feedback you choose to send. If you use the feedback form we receive what you typed, and your name and email only if you decided to fill those fields in. Leave them blank and the message reaches us with nothing identifying attached.
What we never do
No advertising
There are no ads in DTennis and no ad networks in the app.
No analytics or tracking
We do not measure how you use the app, and nothing follows you across other apps or websites.
No selling or sharing
We hold no personal data about you, so there is nothing to sell, share or hand on to anyone else.
Children
DTennis is suitable for all ages and collects nothing from anyone, including children.
Your rights
Rights such as access, correction and deletion apply to personal data a company holds about you. We hold none, so there is nothing for us to retrieve or erase. Your own copy is entirely in your hands: export it whenever you want, and uninstalling removes it.
Changes to this policy
If the app ever starts doing something this page does not describe, we will update this page before that version ships, and change the date at the top.

Terms and conditions
Terms of use
DTennis is made by Dihardja Software. These terms cover what you can expect from the app and what we expect from you. Plain language, no surprises.
Last updated: 26 August 2026
What DTennis is
DTennis is an app for organising tennis: building draws and rotations, recording scores and ranking players. It runs on your own phone or tablet, with no account and no internet connection required. It is published by Dihardja Software.
Your licence to use it
You get a personal, non-exclusive licence to install and use DTennis on devices you own or control, for your own play and for running events at your club, including events you charge players to enter.
You may not resell or redistribute the app itself, or attempt to decompile, reverse-engineer or extract its source. The app, its name, its logo and its design stay ours.
Free and Pro
The free tier is a complete app, not a trial. Tournaments, players, rounds and scoring are never counted or capped on either tier, and backup and restore to a file work on both, so your data is never held hostage.
DTennis Pro is a one time purchase, not a subscription. It unlocks the remaining tournament formats, up to 12 courts, court mode, PDF export, the session clock, leagues, cost splitting and Google Drive backup. It is tied to your Apple or Google store account, so Restore Purchase brings it back on a new phone at no extra cost.
Prices are shown in the app in your own currency and can change over time. A price change never affects a purchase you have already made.
Payment and refunds
Apple and Google take the payment, not us, and we never see your card details. Because of that, refunds are handled by the store you bought from, under that store's policy: through Report a Problem for the App Store, or Google Play's own refund process for Android.
We cannot issue a refund ourselves, but if something has gone wrong, tell us and we will help you sort it out.
Your tournaments are yours
Everything you create in DTennis (tournaments, players, scores, leagues and cost splits) belongs to you and stays on your device. We hold no copy of it, so we cannot recover it for you. How we handle data is set out in the privacy policy.
That makes backups your responsibility. Export a backup file before you change phones, and keep it somewhere safe. If you uninstall the app or lose the device without a backup, that data is gone for good.
Updates and changes to the app
We improve DTennis over time. Some updates arrive through the App Store or Google Play; others download directly into the app without a store update. Features may be added, changed or removed as the app develops.
If a change would remove something you had already paid for under Pro, we will say so before that version ships.
What we do not promise
DTennis is provided as it is. We work hard on it, but we cannot promise it will be free of bugs or that it will suit every event you run.
The app is a tool for organising play, not an authority on it. Draws, pairings, scores and standings are for your group to agree on. If a result is disputed, that is a conversation for the court, not for the app. Check anything that matters before a prize depends on it.
Limits on our liability
To the extent the law allows, Dihardja Software is not liable for indirect or consequential loss arising from your use of DTennis, including lost data, a disrupted event or a disputed result. Where liability cannot be excluded, it is limited to the amount you paid us for the app.
Nothing here removes rights you have under the consumer law of your own country.
Ending these terms
You can stop using DTennis at any time by uninstalling it. We may withdraw the app from sale or stop supporting an older version, but that does not take away a copy already installed on your device.
Changes to these terms
If these terms change, we will update this page and change the date at the top. Continuing to use the app after that means you accept the updated version.
Governing law
These terms are governed by the laws of the Republic of Indonesia, where Dihardja Software is based.
