Hi zhur4ik,
Have you added the app to the Health app on your iPhone?
From Manage Health data on your iPhone, iPod touch, or Apple Watch - Apple Support:
Add information from other apps
1. Open the Health app.
2. Tap your profile picture in the upper-right corner
.
3. Under Privacy, tap Apps. You can see apps that you already own that are compatible with Health. If you don't see an app, it might not be compatible.
4. Tap an app and turn on the health categories that you want that app to track.
You might also need to open the app and adjust its settings to allow it to share data with Health.
If you continue to have an issue, reach out to Apple Support directly to further assist.
