Apple Health

Connect Apple Health and each session you count on your iPhone lands there as a jump rope workout, with its calories and heart rate. The app reads one thing back: your weight, for calories.

What the app reads and saves

The app reads your most recent weight, to estimate calories. It reads nothing else.

For each session counted on your iPhone, it saves:

• A jump rope workout, from the session’s start to its end. Pauses are marked in it, so they stay out of the workout’s duration.
• The session’s calorie estimate, as active energy, when you have a weight. See Calories.
• Every heart-rate reading from your strap, when one was reading. See Heart rate.

Apple Health gets only what you allow. You can share workouts and leave out heart rate, for example.

A session that counted no jumps isn’t kept, in the app or in Apple Health. A session you run on Apple Watch is saved by the Watch, which asks for Apple Health the first time you start one there; its summary says whether it was. See After a session.

Connect Apple Health

One sheet covers both directions: reading your weight and saving your sessions. You can also connect during onboarding, from the Weight sheet, or from a session’s summary. Your other devices with the same iCloud skip onboarding, so the app offers it there once, when you first open it.

Once connected, the Apple Health card becomes a switch. It decides whether new sessions are saved, and it starts on.

On iOS 26 and later, connecting does one more thing: a session keeps running when you lock your iPhone or switch apps. Your headphones keep counting and the voice keeps calling the rounds. See Off screen and on the Lock Screen.

What the summary says

The summary after each session says what happened in Apple Health:

The summary says	What it means
Saved to Health	The workout is in Apple Health.
Not saved to Health	Apple Health isn’t connected yet. Tap Connect beside it, and this session is saved once you allow it.
Health saving turned off	The Apple Health switch in Settings › Profile is off.
Health access turned off	Apple Health doesn’t let the app save workouts.
Couldn’t save to Health	Saving this session failed.

Connecting saves the session on screen and every session after it. Earlier sessions stay out of Apple Health.

Deleting a session

When you delete a session in the app, its Apple Health workout goes too, with its calories and heart rate. Swipe left on the session in Progress › Sessions and tap Delete, or open it and tap Delete session. While Apple Health is connected, the confirmation says so: “Delete this session? Its records, charts and Apple Health workout go with it.”

A few limits:

• The app can delete only what it saved itself. It finds it by the session’s start and end times.
• A session counted on the Watch was saved by the Watch, which deletes its workout the next time its app opens.
• If you stopped letting the app save heart rate or active energy, it can’t delete those either.
• The Apple Health switch plays no part: a deleted session leaves Apple Health even with saving turned off.
• It works one way. Deleting a workout in the Health app leaves the session in the app.
• Deleting the app leaves its workouts in Apple Health. Delete them in the Health app if you want them gone.

Turn off access

To stop saving new sessions, turn off the Apple Health switch in Settings › Profile. The workouts already saved stay in Apple Health.

To take back the app’s access, open the Settings app and go to Privacy & Security › Health › JRProtocol. JRProtocol is the app’s name on your Home Screen. Turn off what you no longer want to share.

Without access to your weight, the app forgets Apple Health’s weight. Enter yours in Settings › Profile to keep calories.

Without access to workouts, summaries say Health access turned off. On iOS 26 and later, a session also pauses when you leave the app.
