“What was the score? I thought I was ahead.”
In the heat of a game the score gets muddled fast. And the arguments follow.
Score disputes
Everyone remembers a different number, and nobody wants to back down.
Losing track
A few long rallies and suddenly no one knows what the score was.
Phone off the court
Pockets are for balls. And clicking the score into your watch mid-game? You'll go off that fast.
Three steps. Pure simplicity.
Place it, click, play. The score keeps itself.
Put DOTTA where you want it
One O-ring, two seconds. On the handle or the throat of the racket, or just on a finger — wherever it suits you.
Click every point you win
Click = point. Hold the button = point back. One button, nothing else.
Live score on your phone and watch
Over Bluetooth, instantly, no hiccups — even on the Lock Screen.
A few grams of honest hardware.
One chip, one battery, one button. Nothing else needed.
Bluetooth
Connects on its own and holds the link all match long.
Swappable battery
A common coin cell. Swap it yourself, never charge.
1.5+ years of play
Playing twice a week, two hours a session.
20–40 m range
20 m with room to spare, 30 m no problem, up to 40 m in good conditions.
One button
Click = point. Hold = undo.
Conceived, designed and handmade in Czechia
We make and test every unit ourselves. A single silicone O-ring holds it — on the handle, on a finger, anywhere.
The weight of a coin — DOTTA is always right there, wherever suits you best, and your racket's balance stays exactly as you know it.
The score lives on your phone and your wrist.
Live match, stats, history and Live Activity — the full app, free, no subscription.
8 sports, one app
Padel, tennis, squash, badminton and more. Golden point, tiebreaks, side changes — DOTTA keeps the rules for you.
Score on your wrist
Raise your wrist and know who's ahead. No reaching for your phone.
One click shows up everywhere
Click once and it's there — on your phone, your watch and the Lock Screen.
6 languages, your colors
The app speaks six languages and wears the same colors as the controllers you pick yourselves.
Stats and match history
After the match you see who held serve, how long the runs were and how long you played. Everything is saved, so today lines up against every match you have played.
Audio mode
Tennis · calling every point
Pair a Bluetooth speaker and the calls carry across the whole court.
DOTTA calls the score. Your umpire in the chair.
Click — and the new score is called out loud for the whole court.
Confirmation on every click
You hear the point register. No phone, no glancing at your wrist.
The score whenever you ask
Lost track? Two quick clicks and you hear it: “In the second set, blue team leads four three in games.” Nothing is scored — you are asking, not playing.
No cheating, no accidental clicks
Everyone hears the score right away. Nothing left to debate.
Tournament wording
“Fifteen love”, “Deuce”, “Game, set and match” — proper ITF calls.
8 voices, two personalities
A straight-faced umpire, or a rather entertaining commentator who riffs on deuces and match points. English and Czech, independent of the app language.
Says exactly as much as you want
Every point, just games and sets, or match only. Volume and the audio-mode settings work from your phone and your watch alike.
One switch in the app settings. The recorded calls currently cover tennis and padel.

What you need to know
Short, honest answers. Where we don’t know for sure yet, we say so.
What devices does DOTTA work with?
iPhone and Apple Watch. Android isn’t supported yet — but an Android app is coming soon.
Does DOTTA call the score out loud?
Yes — switch on audio mode in the app and DOTTA calls the score like a chair umpire: “Fifteen love”, “Deuce”, “Game, set and match”. Eight voices, English and Czech, and over a Bluetooth speaker the whole court hears it. The recorded calls currently cover tennis and padel.
Is there anything to pay in the app?
No. The iPhone and Apple Watch app is complete and free — live match, stats, history, audio mode and firmware updates. No subscription, no in-app purchases. You pay once, for the device.
How do I pair DOTTA?
Over Bluetooth. Switch it on, open the app and DOTTA connects on its own. The app then switches to your colors.
What battery does the DOTTA controller take — and can I change it?
A common CR1620 coin cell — you swap it yourself in seconds. Playing twice a week for two hours, it lasts over 1.5 years.
What's the range?
A comfortable 20 meters, 30 with no trouble, and up to 40 in good conditions. Don't cover your phone too much during play and keep it near the court — that keeps the connection at its most stable.
Where can I clip DOTTA?
Wherever suits you — the racket grip, a finger, or, for all we care, your wrist. A single silicone O-ring holds it: stretch it over DOTTA and you're done. No glue, no tools, and you can move it any time.
Will DOTTA change my racket's balance?
No. It weighs 5 grams — about a coin. The added mass is so small, and so close to your hand, that the balance you're used to stays.
Where do you ship?
We're starting with Czechia and Slovakia, and shipping is completely free.
Can I return it?
Yes. Within 14 days of delivery, no reason needed — returns inside that window are free, and we’ll send you a prepaid return label. The form is on the Withdrawal page.
