Recording
Choose Record Score to enter a result after playing. Choose Start Live Match to record each point as you play.
Tap Undo before saving the match. You cannot undo individual points after the match is saved.
For a match you created, open its details and tap Edit. Changing the result does not rebuild its point-by-point history.
Yes. Stop scoring, check the current score, and tap Save.
Choose Save & Leave to review and save the score, Discard & Leave to discard the unsaved session, or Keep Playing to return. Closing the result preview does not save the match.
No. Unsaved matches won’t be restored if the app closes. Save before leaving. Switching briefly to another app or locking the screen keeps a session only while the app remains alive. Saved matches, pending uploads, and Watch records are separate.
No. Save before refreshing or closing. A brief switch away can keep the current page alive, but the browser cannot guarantee a warning before closing. If saving fails, keep the page open and retry. If your session expires, sign in to the same account to save the current match.
Yes. Select the people who are playing. The match goes into Others’ Matches and does not count toward your own win rate.
Scoring Rules
Standard uses games and sets. Tiebreak counts points directly toward a target score.
At 40–40, Advantage requires two points in a row to win the game. With No-Ad, the next point wins the game.
The target is 7 or 10 points. In both cases, you must lead by at least 2 points to win.
Yes. Choose Tiebreak, enter Number of Rounds, and choose the point target. Every round uses the same target and requires a 2-point lead. All configured rounds are played, even if one side already has more wins. The next round starts with the player after the previous round’s first server.
The match score counts rounds won, and each Round shows its actual point score. An even number of rounds can end in a draw. Saving early counts a leading unfinished round; tied unfinished rounds do not add a win. A single-round match keeps its point score as the main result.
On iPhone, set Match Format before starting. Open Advanced Settings for more options, including tiebreak and deciding-set rules.
Move to the other end of the court. This reminder does not change who serves next.
Friends & Sharing
A local player is a name you save for an opponent or partner. They do not need an account, and you can link them to a real friend later.
Sign in, open Players, and search by their full email address, Player ID, or nickname. Check the result before sending a friend request.
You connect that saved player to a real friend and share the past matches that can be shared. Review the match list before confirming.
Yes. Each local player can link to only one real account, but several local players can link to the same account. Matching names are not merged automatically.
No. It only accepts future shared matches. You still need to accept or decline friend requests yourself.
No. Shared results exclude your private notes, email address, and health data.
Open the link, sign in or create an account, then return to the same match and select your place. Signing in does not submit a claim. The creator must approve your request before you receive a copy. Private notes, health data, email addresses and internal user IDs are not public.
Existing shared matches stay in both accounts but stop receiving updates. Adding the friend again does not restart updates to those old copies.
Devices
Install the companion app on the Apple Watch paired with your iPhone. You do not need a pairing code in this app.
On your watch, open Settings → Display & Brightness → Wake Duration → Wake for 70 Seconds. This changes the system wake duration, not an unlimited screen-on mode. Always On depends on your model and system settings: SE 3 supports it; SE and SE 2 do not. Low Power Mode may disable Always On. DeuceCount cannot force these settings.
No. Save matches on the watch and transfer them when it can connect to your iPhone. Backing them up to an account is a separate step that needs sign-in and internet.
Check Matches on the watch first. Bring the devices close together and open both apps. Saved matches transfer automatically when the paired apps can communicate. Keep the local record if transfer or account backup fails. New Watch match formats require the updated iPhone App.
Yes. Use Score Only if Health access is unavailable. The Watch App checks whether Health permissions need to be requested when it first opens. Granting access does not start a workout; Start Workout starts it and checks workout writing access again.
In Settings, change Watch Settings and tap Apply to Watch. The iPhone Settings section only controls matches recorded on your phone.
Tap Start Workout to begin one tennis workout. You can create and save several matches during it; saving a match returns to preparation and keeps the workout running. Use Controls → End Workout to finish the whole workout. Returning home does not end it.
Swipe right from preparation or scoring to the left-hand Controls screen, then tap Pause. Workout time, match time, point entry and automatic score prompts pause together. Tap Resume to continue, and swipe left to return. Leaving From iPhone cancels that waiting request. The waiting screen reconnects automatically when the paired apps can communicate; no Retry button is needed.
Yes. If workout writing is unavailable, use Score Only. Match records and local timers still work. A missing heart-rate sample is shown as a dash; it does not prove that access was denied. Local timers alone do not provide HealthKit background sensor recording.
Start a workout on Watch and choose Create on iPhone. In the paired iPhone App, choose Start Live Match, configure the players and rules, and start. The Watch must confirm before both devices open the same match. Ordinary iPhone matches stay independent when Watch is not waiting.
Keep scoring on Watch. iPhone shows the last confirmed score and remains read-only. Reconnect and refresh before entering another point. If an operation was not confirmed, retry that same operation; it will not add a second point. Closing iPhone does not end the Watch workout.
Watch creation does not set a fixed match length. After each set, choose Next Set or Save Match; standalone tiebreaks use Next Round. The choice waits for you, and a match can be saved as a draw. iPhone-created matches keep the fixed length and advanced rules chosen on iPhone.
For a match created directly on Watch, swipe left from scoring and choose Change Format. Std and Tiebreak keep separate progress for the current game; the first switch starts the other format at 0:0. Apply submits the choice and tiebreak target. Winning settles that one game, and the next game follows the original match format. Only the chosen branch contributes to saved statistics. iPhone-created matches use the format set on iPhone.
No. Home Settings and iPhone Apply to Watch change defaults for future workouts. In-workout Options apply to the current workout. Sound and haptics use Watch settings; iPhone feedback uses its own settings.
Workout time includes preparation and breaks between matches. Match time begins when that match starts. Both exclude pauses. Match details do not copy the workout’s entire energy or average heart rate into every match.
Not yet. Garmin Watch support is coming soon.
Account & Data
No. It means the match is saved on the device. Account backup also needs sign-in and internet; if upload fails, keep the local record and retry when connected.
Open its message in Inbox and tap Accept Match. You need to do this when automatic acceptance is turned off.
They are app announcements in Inbox. You can read them, but you cannot reply.
System messages are currently shown inside the app, not as push notifications. Open Inbox to read them.
Open Profile → Account Management while signed in. Choose Sign Out, or open Delete Account and Data to read the effects before confirming deletion.
No. New accounts choose 4–20 letters, numbers or underscores after verifying their email. IDs are case-insensitive and cannot be changed or reused after account deletion. Existing accounts keep their current ID. You can still change your display name.
No. Registering again will not restore deleted data. Other players may still have copies of matches you shared with them.
No. Manage or delete those workouts separately in Apple Health.
