DeuceMate Support

Everything you need to start scoring — plus troubleshooting and answers to common questions. DeuceMate is free and private, and core scoring and match review work offline.

Free · no ads No developer data collection Core works offline Singles & doubles

Getting started

Start a match

  • Open DeuceMate on your Apple Watch and tap Start Match.
  • Choose singles or doubles, enter names (optional), and pick your match format.
  • Select who serves first, then start scoring.

Score on the watch

  • Swipe up — award a point to you
  • Swipe down — award a point to your opponent
  • Swipe left — undo the last point (full game-state rollback)
  • Swipe right — open the live stats view
  • Double tap — toggle second-serve context

Review on the iPhone

  • The iPhone companion shows a live scoreboard during a match, plus your full match history and detailed per-match and per-set statistics.
  • No account, no login — core scoring and history work offline.

Key features

  • Automatic tennis scoring — points, games, sets, tiebreaks and super tiebreaks, with correct server rotation and side-change reminders.
  • Multiple formats — best-of-3, full final set, super tiebreak, and more; singles and doubles with full service-order management.
  • iPhone live scoreboard — mirrors the watch in real time over Apple's WatchConnectivity.
  • Spoken score announcements (iPhone) — umpire-style calls while the app is open on screen. Keep DeuceMate in the foreground courtside; announcements pause if the phone is locked or the app is in the background. Routes through the iPhone speaker or a connected Bluetooth speaker.
  • Statistics & coaching insights — serve, return, break points, winners/errors, pressure points, rally depth, and an interactive points graph.
  • Optional fitness tracking — link a HealthKit workout for live heart rate, calories, steps, distance, and heart-rate-zone stats. Entirely optional.
  • Optional Court Compass — "Check Changeover" reads the watch's compass heading (no GPS, no location tracking) to show which end to take.

Troubleshooting

Spoken announcements aren't playing

  • Turn on Announce scores aloud in the iPhone app's Settings.
  • Keep the iPhone app open on screen during the match — announcements are foreground-only and pause when the phone is locked or the app is backgrounded.
  • Check the phone isn't on silent/low volume, and that the right Bluetooth speaker is connected.

The watch and iPhone aren't in sync

  • Make sure both devices are paired and the DeuceMate iPhone app is installed.
  • Open the iPhone app's Settings → sync diagnostics and tap Sync Now or Ping Watch.
  • Keep both devices nearby and unlocked while a live match is in progress.

Match state was lost

  • DeuceMate auto-saves an in-progress match when the app is backgrounded — reopen it to restore.
  • If the watch storage is full, the save may have failed.

Migrating to a new device

An Apple device backup or DeuceMate's automatic iCloud Drive restore brings back your matches, scores, and non-health statistics. Recorded heart rate, steps, distance, and calories are kept in backup-excluded local storage and are not included in either automatic restore path.

Before switching iPhones, open Settings → Backup & Transfer → Export Match Archive. On the new iPhone, choose Import Match Archive. This manual file is the explicit, user-controlled full-fidelity transfer and may include those fitness metrics; you choose where to save or send it.

This design follows four principles: Health-data compliance; device-local fitness data by design; a useful but partial automatic restore for scores and non-health stats; and manual export as the user-initiated migration carrier.

Frequently asked questions

Does DeuceMate work offline?
Core scoring, match history, and analysis work without an internet connection. Watch ↔ iPhone sync is local. Personal iCloud Drive backup and any sharing or AI hand-off you choose require the relevant Apple or third-party service.
Is my match data synced to the cloud?
Watch ↔ iPhone sync is on-device peer-to-peer over Apple's WatchConnectivity, with no developer-controlled server. When iCloud is available, the iPhone app also keeps an automatic archive in your personal iCloud Drive for fresh-install restore, with HealthKit measurements removed; the developer cannot access it. Data may separately leave your devices when you deliberately export or share it, and is then handled by the recipient or service you choose.
Is there an iPhone app?
Yes — DeuceMate is an iPhone app with a bundled Apple Watch app. You score on the watch; the iPhone companion gives you a live scoreboard, spoken announcements, unlimited match history, and statistics.
Can I review past matches?
Yes. Every completed match is saved to an unlimited on-device history in the iPhone app, with full per-match and per-set statistics.
Can I back up or move my match history to a file?
Yes. In the iPhone app, Settings → Backup & Transfer lets you Export Match Archive to a single full-fidelity file (it includes any heart rate, steps, distance, and calories you recorded) and Import Match Archive back — on the same phone or a new one. On import you choose how it combines with what's already there:
  • Merge keeps your current matches and adds the ones from the file. If a match is in both, it keeps the more complete copy — so you won't lose health data or finished results — and brings back any match you'd previously deleted if it's in the file.
  • Replace swaps your iPhone archive for exactly what's in the file. Matches not in the file are removed from the iPhone (though any still on your Apple Watch can sync back), so the app asks you to confirm first.
This is a manual file you control, and is separate from the automatic iCloud backup.
Can I share a match with someone who doesn't have DeuceMate?
Yes. From a match's detail view, the Share menu's Interactive Web Page exports the whole match as a single self-contained .html file. It opens in any web browser — on a phone, tablet, or computer — with the momentum chart, the full you-vs-opponent stats (with Stats/Points tabs and per-set filters), a point-by-point list, and a built-in AI-coach launcher. The file works completely offline and uploads nothing; you choose who to send it to. (If a file preview can't run scripts — like the iPhone's Quick Look — it still shows a full static report; open it in a browser for the interactive version.)
Does it work for doubles?
Yes — singles and doubles are both supported, with full four-player service rotation in doubles.
Can I use it for padel?
Yes. Padel uses the same game/set scoring structure as tennis, so DeuceMate keeps score for padel too (tennis-only rule tips won't all apply).
Are there subscriptions or in-app purchases?
No. DeuceMate is completely free — no subscriptions, no in-app purchases, and no ads.
How do I manage HealthKit access?
Fitness features are optional. You can review or revoke DeuceMate's HealthKit access any time in the Apple Watch Settings app or the iPhone Health app.
