Lap Counting Accuracy Issues?

If Swim.com is undercounting your swim distance:✅ Use a flip turn or open turn at the wall.
✅ Push off with a strong glide to reset stroke tracking.
Avoid stopping mid-length or changing stroke types frequently.

For drills like kickboard sets, enable Drill Mode to manually log your distance.

To view HR data:

  1. Open your Swim Details in the iOS app.
  2. Swipe right on the Workout Summary to reveal Heart Rate Metrics.

⚠️ Apple Watch heart rate readings in water may appear higher than actual HR.

You can change distance units on either:

  • Apple Watch → Tap Unit (Meters/Yards) in Workout Settings.
  • iOS App → Go to Settings > Devices > Apple Watch > Distance Units.

Other Features
