Fix Apple Watch Open-Water Swimming Distance wrong

Apple Watch can underestimate open-water swim distance, especially during breaststroke.

In my 1,000 m race, Apple Fitness recorded just 115 m. With SwimNow’s Distance Correction, it reached 924 m—much closer to the actual distance.

Swim-tastic App

Useful app for data on each swim, trends and workout suggestions. The AI feature is interesting and improving with each update for session insights.

Swimming Must Have!!

Such an incredible app! My wife and I started taking fitness (mainly swimming) more seriously this year and this app is unreal. So much more data than what Apple workout sessions show, and the new Ai feature is also great and telling you how to improve! Extremely easy to use, and the stickers add an extra motivation! Also seeing how many calories you burnt over the weeks / months in the form of burgers is amazing and I hope that never changes 🤣
5/5

Brilliant

Excellent app. Provides a really nice month-month and year-year overview of session frequency as well as detailed analysis of individual sessions. Easy way to keep track of PBs and I love the end of year recaps and new AI insights. This app is excellent value for money, love it!
5/5

Easy to use

This app is very easy to use. It gives detail report of your swim which is recorded by native watch activities app. Very helpful for every level. Activities template is the best feature to import in apple watch.

Great app for Apple Watch

This app is simple to use. This app is simple to use. I like that it is integrated with my Apple Watch without me having to do anything. I like that it tracks my progress. I am so slow that it’s hard to tell I am improving, but this app shows I am, and this gives me hope.

Love this app!

I was going around in circles trying to find my swimming workouts and manually writing my own summary and then I found this app! Thank you for creating something so easy to use and with such a great display of info. As they say understanding data is key to achieving your goals and with this app I am keeping motivated and can see my improvements easily.

Frequently asked questions

Help with your swimming data and settings.

How does it work?

SwimNow seamlessly syncs swim data via Apple Health, enabling cross-device tracking and centralized analysis

  1. Devices → Apple Health

    Apple Watch or Third-party apps/devices (Garmin, Sunto, etc.) upload swim metrics (distance, strokes, SWOLF) to Apple Health.(Data granularity depends on the range of metrics provided by third-party devices/apps.)

  2. Apple Health → SwimNow

    SwimNow securely pulls authorized data via Apple Health’s API. Grant permission once—done.

How do I manually add swimming data?
  1. Open the Health app on your iPhone.

  2. Search for Workouts.

  3. Open the Workouts page and tap Add Data to enter your session.

Why can’t I find the Apple Watch app?

SwimNow does not have an Apple Watch app. We recommend using the built-in Workout app to record your swimming sessions.

Why isn’t my data syncing?
  1. SwimNow syncs through Apple Health. Check that your swimming data is saved in the Health app.

  2. Check Health permissions: open Health, tap your profile picture, go to Apps, select SwimNow, and enable access to all relevant data categories.

How do I set the first day of the week?
  1. Open Settings on your iPhone.

  2. Go to General → Language & Region.

  3. Select First Day of the Week and choose your preferred day.

Can I sync data from other devices?

If your device supports syncing swimming data to Apple Health, SwimNow can read that data after you grant access.
