Short answer
A watch measures your body: heart rate, calories, time on court. A sensor on the racket measures your shots: which ones you hit, how well, and how often they went wrong. With Padelplay you don't have to choose. The app connects to Apple Health and Google Health Connect, so your watch's heart rate and calories sit next to your shots in one place.
What a smartwatch measures during padel
Smartwatches are excellent at measuring effort. During a padel match a good watch records:
- heart rate and time in each heart-rate zone;
- calories burned;
- duration of the session;
- steps and, outdoors, sometimes distance.
Some watches offer a padel or racket-sports activity profile. That makes the workout easier to log, but the measurement is still about you, not about your shots. A watch doesn't know whether you just hit a bandeja or a lob, whether your smash was good, or how many points you gave away.
What a padel sensor measures
A padel sensor sits on the racket and measures how the racket moves through every swing. From that it can tell you:
- Which shots you played: forehand, backhand, volley, smash, bandeja, lob and slice, and how they are distributed.
- How good your smash is: a quality score per smash, not just a count.
- How many mistakes you made: the points you lost on balls you should have controlled.
- How your game changes: trends across sessions, so you can see whether training is working.
Why a wrist can't see your shots properly
A smartwatch sits on your wrist. The ball meets the racket head, about half a metre further on. A flat forehand, a sliced backhand and an overhead can look surprisingly similar from the wrist, especially when technique is not perfect. Even dedicated wrist-worn padel trackers struggle with this. A sensor on the racket measures the thing that hits the ball, which is why it recognises shots far more reliably.

Which one should you get?
You want to get fitter
Or you play several sports: a smartwatch is the right tool.
You want to win more matches
A padel sensor. Fitness helps, but most points at club level are decided by shot choice and mistakes, and that is what a sensor shows you.
You already own a smartwatch
Keep it and add a sensor. They measure different things, and Padelplay brings both together in one app.
Better together: your watch and your sensor in one app
The most complete picture comes from combining both. Padelplay connects to Apple Health on iPhone and Google Health Connect on Android. Your smartwatch keeps measuring your heart rate and calories as usual, and the Padelplay app shows that data alongside your shots, smash quality and mistakes for the same session.
Seeing effort and quality side by side helps you spot patterns neither device shows on its own, for example whether your mistakes pile up in the sessions where you were working hardest.
Do I need my phone on court?
For Padelplay, yes: keep your phone nearby, for example in your bag next to the court. The sensor sends your shots to the app over Bluetooth during the session, so the phone needs to stay within range.
Padelplay is a 15.6-gram sensor that sits at the bottom of your racket handle. It recognises seven shot types with 85% accuracy or higher depending on the shot, lasts up to 8 hours of play per charge, is waterproof, and works with the free Padelplay app on iOS and Android. See how Padelplay works.
