How to use your Omron blood pressure monitor with FourNumbers

How FourNumbers gets your readings

• From Apple Health, automatically. FourNumbers only reads blood pressure and pulse from Apple Health. It never writes or changes anything there.
• Take a photo of your monitor's screen.
• Type it in.

It works with any upper-arm or wrist cuff.

Step 1: Link Apple Health in OMRON connect

1. Go to Profile > App settings.
2. Under "Share data with other apps", tap Apple Health > Link.
3. Turn on the data types, then tap Allow / Done.

In some versions this is under a "More" tab.

Step 2: Let FourNumbers read Apple Health

Open FourNumbers and allow Blood Pressure and Heart Rate when iOS asks for Apple Health access.

To check later: iPhone Settings > Apps > Health > Data Access & Devices (or Health app > your profile picture > Privacy > Apps).

Tips

• Omron only shares to Apple Health while it's turned on inside OMRON connect. If it shows as inactive, open the same screen and link it again.
• The iPad version may not offer Apple Health — use your iPhone.
