Find out how to connect and sync your Garmin, Suunto, Apple or Wear OS watch (Samsung Galaxy, Pixel) to the Catch app. Send your sessions to your watch and let your watch guide you through your swim.
Good news - setting up Garmin with Catch only takes a minute. Once it’s connected, your swim sessions will automatically sync both ways: from Catch to your watch, & from your watch back to Catch.
To connect your Garmin:
When you next open the app, your planned sessions will automatically appear on your Garmin, & your swims will sync back into Catch once they’re saved on your watch.
💡 Tip: If you ever need to reconnect (for example, after a Garmin app update), just repeat these steps.
Once your Garmin is connected, following your Catch swim sessions on your watch is easy.
To start your guided swim:
Open your Garmin watch
For a pool swim:
Your watch will guide you through each rep & rest. It’s a seamless, zero faff way to tick off your sessions.
| Lap button | Press this when you finish each rep. |
| Skip forward | Press the Lap button again to move on to the next part of the session. |
| Pause/Resume | Use the Stop/Start button if you need a longer rest (or fancy a quick chit chat). |
Depending on which Garmin model you have, the watch might buzz on your last length. This is normal and is designed to let you know that you're nearly at the end of the rep.
When you’re done, save your activity on your watch. It’ll automatically sync back to Catch the next time your Garmin connects.
Good news - setting up Apple Watch with Catch only takes a minute. Once it’s connected, your swim sessions will automatically sync both ways: from Catch to your watch, & from your watch back to Catch.
To connect your Apple Watch:
Your swims will also sync back into Catch once they’re saved on your watch. Head back to the Catch app after your swim to see your stats. Catch will analyse your swim and feed this back into your training plan.
Note: Make sure you select the correct day in the Catch app before sending. If you have selected a different date, click the 3 dots to view all Catch workouts and you'll find it there.
Once your Apple Watch is connected, following your Catch swim sessions on your watch is easy.
To start your guided swim:
Open your Apple watch
For a pool swim:
Top tip: If you want a little longer to prepare for your first rep, press pause as soon as the countdown ends and the instructions appear.
When you're ready to swim, resume by pressing the same buttons again.


| Pause/Resume | On newer Apple Ultra watches, you can press both the "action" button and "side" button at the same time. On all other Apple watches press the "side" button and the "digital crown" at the same time. |
| Lap button | The "action" button on newer Apple Ultra watches. |
| Skip forward | Turn off the water lock by holding down the digital crown. Swipe right, select "Next". |


Water lock: During a swimming workout, the touch screen locks. You can unlock it by long pressing the digital crown.
We don't recommend you do this until the end of the swim, when you want to end the workout.

Good news - setting up Suunto with Catch only takes a minute. Once it’s connected, your swim sessions will automatically sync both ways: from Catch to your watch, & from your watch back to Catch.
To connect your Suunto:
When you next open the app, your planned sessions will automatically appear on your Suunto, & your swims will sync back into Catch once they’re saved on your watch.
Once your Suunto is connected, following your Catch swim sessions on your watch is easy.
To start your guided swim:
Navigate to the Exercise section on your Suunto watch
For a pool swim:
Your watch will guide you through each rep & rest. It’s a seamless, zero faff way to tick off your sessions.
| Lap button | Press this when you finish each rep. |
| Skip forward | Press the Lap button again to move on to the next part of the session. |
| Pause/Resume | Use the Stop/Start button if you need a longer rest (or fancy a quick chit chat). |
When you’re done, save your activity on your watch. It’ll sync back to Catch automatically.

Our own Catch app for Samsung Galaxy Watch, Google Pixel Watch and other Wear OS watches. There's nothing to sign in to: your phone sends this week's sessions to your watch, and your swims come back the same way.
Unlike the other watches, this is our own app. It was built for the pool. You control it with your watch's button or crown, as the touch screen doesn't work well in water. It buzzes as you start the last length of each rep, and it shows what's next while you rest.
This week's sessions, ready on your watch
Planned Catch pool sessions, or record your own session
Every rep's distance and pace when you finish


There's no account to link. This week's sessions go to your watch whenever you open Catch on your phone. The first time, you'll also be asked about Health Connect: allow it to see your swims in Samsung Health and other health apps.
No plan today? Free swim sits at the bottom of today's sessions. It counts your lengths and time, and you mark reps yourself.
The first time you open a session, How it works teaches the controls with a quick practice. You'll find it again at the bottom of every session.







You control Catch with your watch's button or crown, as the touch screen doesn't work well in water. Which one depends on your watch.
| To | Galaxy Watch · buttons | Pixel Watch · crown |
|---|---|---|
| Finish a rep | 2 clicks | Turn away |
| Skip a rest | 2 clicks | Turn away |
| Pause or resume | 1 click | Turn towards you |
| End the swim early | Pause, then 2 clicks, then 2 clicks again to end and save | Pause, then Turn away, then Turn away again to end and save |
Galaxy: use the lower button. Press it, don't hold it: holding it opens Samsung Wallet. Two clicks means two quick presses. If the screen has gone dark, your first press just wakes it.
Pixel: keep turning until the ring on screen fills. The ring tells you what the turn will do.
The screen ignores touches while you swim, so splashes can't change anything. Don't turn on your watch's water lock: Catch handles that for you. Rests count down and move on by themselves. Reps don't, so tell the watch when you touch the wall.
Didn't mean to record it? Scroll down on Done, tap Delete swim and hold for two seconds. It won't be saved or sent.
