Syncing to Apple Watch

Your workout. Your watch. Your wrist.

Phone-free training starts here. This guide covers everything you need to pair your Apple Watch with your ROXFIT account. From syncing your PaceMe splits before race day to training with accuracy and reminders. Set it up today so that when you're ready to go, you're not fumbling with a screen.

1. Pairing your Apple Watch

No separate login, no account linking. Your Apple Watch connects to ROXFIT automatically as long as it's paired to the same iPhone.

What you need

  • iPhone with ROXFIT installed
  • Apple Watch paired to the same iPhone
  • ROXFIT Watch app installed (it comes bundled with the iOS app - you may just need to confirm installation)

Steps

  1. Open ROXFIT on your iPhone.
  2. Tap the profile icon in the top-right corner.
  3. Tap Devices or Add Device.
  4. Select Apple Watch. ROXFIT will detect and register it automatically.
Watch not showing up? Make sure it's paired to your iPhone in the Watch app, within Bluetooth range, and that the ROXFIT Watch app is installed. Check under My Watch > Installed on Apple Watch.

2. Granting permissions

The first time you open ROXFIT on your watch, it'll ask two things of you: Health & Workouts and Motion & Fitness permissions. Say yes to both. We need them to track your heart rate, record your sessions, and log your calories. You didn't train this hard to finish a session with nothing to show for it.

3. How workouts get to your watch

ROXFIT workouts and race simulations aren't browsed on the watch. You find or build them in the app, then push them across. The watch is your player. Your phone is your control room.

The first time you open the ROXFIT app on your watch with nothing synced, you'll see exactly what to do:

  1. Open ROXFIT on your iPhone
  2. Find or create a workout
  3. Tap the watch icon to send it

Once it's synced, it appears in your watch's workout list automatically. You can have multiple workouts on your watch at the same time - useful if you're training multiple times in a week or day.

4. Syncing your PaceMe splits

If you've built your race plan in PaceMe, this is how it gets onto your wrist. Your pace targets are in the workout, so you'll see at every station whether you're ahead or behind your goal. All of it in real time, as you race.

Haven't set up PaceMe yet? Do that first: PaceMe guide here.

Steps

  1. On your Race Calculator page, tap the event you wish to race, then tap Add pacing to wearable.
  2. Select your Apple Watch from the device list and tap Confirm.
  3. Choose your settings. We recommend Auto sport detection - this means when you select a Run activity it will appear as an option to complete the workout.
  4. Tap Sync to Apple Watch.
  5. Wait for the confirmation: "Workout synced to [Watch Name]!"

During the race, you'll see a live pace delta - seconds ahead or behind your target at every checkpoint. Race to a strategy. Execute the plan. That's the whole point.

5. Syncing a training workout

Any ROXFIT workout - training sessions, custom builds, plan workouts - can go straight to your watch from the workout preview screen.

Steps

  1. Open the workout in the ROXFIT app on your iPhone.
  2. Tap the Add to Wearable button at the top of the workout preview.
  3. Select Apple Watch from the device list.
  4. Choose your sync options.
  5. Tap Sync to Apple Watch.
  6. Wait for the confirmation: "Workout synced to [Watch Name]!"

7. Running your workout

Steps

  1. Open ROXFIT on your Apple Watch.
  2. Tap your synced workout.
  3. Swipe to the Timer tab.
  4. Tap Start.

During the session: current exercise, targets, and time remaining are on screen. Heart rate tracks continuously. For PaceMe workouts, your pace delta runs live. The workout auto-advances between timed exercises - for rep-based movements, use the knock gesture or Action Button to move on.

When you finish, you'll see your total time, average heart rate, and calories. You can then view your results in greater detail in the ROXFIT app.

8. Viewing your results

Results sync from your watch back to ROXFIT on your iPhone automatically. No manual upload needed.

Tap Exit Workout on the completed screen. If you need to end early, pause and select End & Save. Don't tap Discard - that permanently deletes the session and it's gone for good.

What syncs to your phone

  • Exercise splits and times for each exercise/station
  • Heart rate data throughout
  • Calories burned
  • Overall duration
  • Pace delta vs target (PaceMe workouts only)
  • Which Apple Watch was used

Sync Queue

All completed workouts are stored on your watch until they've successfully synced. Check status in the ROXFIT app on your watch under Sync Queue - Pending, Syncing, Synced, or Failed. Failed workouts can be retried as many times as needed and won't be deleted until they've synced. Everything is kept for up to 7 days, so even if you're without your phone on race day, your data is safe.
