how to remove health and fitness data from iPhone and Apple Watch using the Health app

Apple’s Health app records and keeps a lot of your activity and health data, especially when you connect third-party apps to it.

If you decide you want to delete some or all of your data from your iPhone or your Apple Watch, this article outlines just how to do that!

There are other reasons to remove health data, from cleaning out storage hogs, removing old and no longer needed health information, or getting rid of someone else’s data that was stored on your device. And the good news is that you can remove all or just some of your health data and you can pick and choose which third-party app data you want to delete too–you have choices!

Remove your activity history from your Apple Watch

The Apple Health app consolidates health data from your iPhone, third-party apps, and syncs information directly from your Apple Watch.

While Apple stores all of your health and activity history on your paired iPhone, your Apple Watch does retain your most recent data. This data includes things like daily tracking of your Activity.

The most comprehensive way to remove any fitness, activity, or other health data from your Apple Watch is to unpair your watch from your iPhone and then re-repair. unpair apple watch from iPhone

Change which apps can read and write Health data using your Apple Watch

Rather than unpair or reset your calibration, you may want to remove app access to your Apple Watch instead.

Manage apps on your Apple Watch by going to Settings > Health > Apps and adjust which apps have access.

FAQs FAQ frequently asked questions

How do I delete an old Apple Watch from my iPhone’s Health app that I no longer have?

Each time you unpair your Apple Watch, the Health app creates another device entry. And unfortunately, even when you restore your watch from a backup, the Health app does not consolidate that data into a single Apple Watch entry.

So if you delete one of your older Apple Watch listings under the Health app’s devices, you lose that data.

If you are okay with that, go to your iPhone’s Health app and tap your profile picture or icon. Under Privacy, choose Devices (or Sources on older iOS versions) and tap each entry to see if you want to remove that data or not. delete a data source from the Health app on iPhone
