Have an original or Series 1 Apple Watch and love swimming? With Swimtivity, you can get credit for your swim workouts in the Apple Watch Activity Move ring--without risking your watch in the pool.

And if you did another type of exercise but forgot to wear your watch, you can add a custom workout with Swimtivity to get credit for those calories, too!

After your activity, use the Swimtivity iOS or Apple Watch app to enter your workout information. Swimtivity does a very rough calculation of your calories burned. If you already know your calorie count, you can manually change Swimtivity's calculated calorie count to match.

Workouts are saved to the Health app and the entered calories count towards your Move goal. And workouts entered with the iOS app will count towards your Exercise goal.

When you enter an activity on your Watch, a force press on the details page allows you to switch between yards and meters.

As of version 2.0, the iOS app allows you to enter activities. It also displays a list of activities entered with Swimtivity.

Note: Due to limitations with the Health API, you will NOT get credit for the Exercise ring when entering activities with the Watch app.

Please don't wear your original or Series 1 Watch in the pool; Apple doesn't recommend it, and it's not required for Swimtivity.

What’s New

Version 2.1

- Added a default duration to iOS activity entry. Activities with very short durations result in odd behavior when adding calories to the Move ring.
- Minor bug fixes.

Only works for the current day

It will show greyed out minutes and calories but will fill your rings it even does my stands. The only problem is it only works for the current day you can not go back in time and have it count towards your rings. I forgot my watch the other weekend when I went out of town and wanted to be able to go back and input my data to keep my streak alive. If this app could do that it would be 5 stars and a top seller.

1 for 2 getting data into Apple Watch Activity

Thanks for making this app. I think it must be an Apple WatchOS limitation, but this app loads the calories into the Apple Watch Activity app but not the time of the swim. So you get progress on the pink ring, but not the more challenging yellow ring where you try to get 30 minutes of Exercise per day. Hopefully at some point the Activity app will be able to update this in the rings. In the Activity app on the iPhone, you can scroll down the page, see your swimming workout under Other, and going into that it does show the exact minutes of your just update the yellow ring with those minutes. C'mon Apple!

It’s not a bad option... but this app has so much more potential when it comes to swimming , tracking calories, and a more complete apple health kit integration.
