FAQ

Questions? We've got answers.

I "purchased" the app but I can't find it on my Watch +

Method 1: directly on the Apple Watch (the "Purchases" menu)

If you want to download it directly from your wrist:

  1. Press the Digital Crown to open the Home Screen.
  2. Tap the App Store app.
  3. Scroll all the way to the very bottom of the main App Store screen.
  4. Tap Account.
  5. Tap Purchased (and then My Purchases if prompted).
  6. Scroll down to find the app and tap the Cloud icon to download it to the Watch.

Method 2: using the iPhone Watch app (usually easier)

This is typically the fastest way to push an already-purchased app to your watch:

  1. Open the Watch app on your paired iPhone.
  2. Make sure the My Watch tab is selected at the bottom left.
  3. Scroll all the way down past the system apps to the Available Apps section.
  4. Find the app in the list and tap the Install button next to it.

Pro tip: check if you have Automatic App Install turned on — on your iPhone, go to Watch app > General > Automatic App Install. When enabled, future Watch apps you download on your phone automatically push to your wrist.

How do I install the Web App on my phone? +

Once installed, it opens full-screen from your home screen, no address bar, just like a native app.

On iPhone (Safari)

  1. Open the Web App using Safari (Add to Home Screen only works from Safari, not Chrome or other browsers).
  2. Tap the Share icon (the square with an arrow pointing up) in the toolbar.
  3. Scroll down and tap Add to Home Screen.
  4. Tap Add in the top-right corner.

On Android (Chrome)

  1. Open the Web App using Chrome.
  2. Tap the three-dot menu in the top-right corner.
  3. Tap Add to Home screen (or Install app, if Chrome offers it directly).
  4. Tap Add (or Install) to confirm.
What's the difference between the Watch app and the Web App? +

They share the same core dashboard — live speed, max speed, Course Over Ground heading, and elapsed time — and both need Location access to work. Beyond that, they're built for different situations:

Watch app

Native to the Apple Watch. Every session is automatically saved as an Apple Workout, so you get a full history in the Fitness and Health apps.

Web app

Runs right in the browser on any phone or computer — no App Store needed, works on iPhone and Android alike, and you can install it to your home screen. It now also includes a live speed chart of your last hour on the water. Since it's browser-based, it only remembers your most recent session (stored privately in your browser, never sent anywhere) rather than keeping a full workout history, and you'll need to keep the tab open and in the foreground while tracking.

How do I end a session on the Apple Watch app? +

When you start tracking, the app automatically turns on Water Lock to protect the screen from water and stray taps — you'll see a small blue water-drop icon on your watch face while it's active. Since the touchscreen is locked, you'll need to turn Water Lock off before you can tap anything:

  1. Press and hold the Digital Crown until you see water droplets spin off the screen — this disables Water Lock and unlocks the display.
  2. Swipe right to get back to the workout controls.
  3. Tap End, then confirm, to finish the session.
