Health app stopped working

Hello Roox,

Thank you for using Apple Support Communities.

If you are having issues with the Health app not working, we would recommend starting with the steps in this article: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

1. Close and reopen the app. Force the app to close. Then open the app to see if it works as expected.
2. Restart your device. Restart your iPhone. Then open the app to see if it works as expected.
3. Check for updates. If updates aren't available for the app, update the software on your iPhone or iPad.
4. Delete the app, then ere download it. Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.

If you are still having issues after this, let us know and we can go from there.

Best regards.
