General information only, not medical advice. Category labels are informational and not a diagnosis. If readings are often high or you feel unwell, see a doctor. Emergency signs such as chest pain, severe headache or shortness of breath need urgent care.
How to use
- Enter systolic, diastolic and pulse, plus the date and time of the reading.
- Click Add reading — it is saved in your browser and added to the log.
- Watch the trend chart and the 7 day and 30 day averages over time.
Note: Rest 5 minutes before measuring, sit with your back supported and your arm at heart level. This tool stores data only in this browser on this device.
Tips
- Measure at the same times each day for a fair trend.
- Avoid coffee, exercise and smoking for 30 minutes before measuring.
- Take two readings a minute apart and log both — the log shows them all.
- Bring your log to doctor visits; the trend often matters more than one reading.
