It's useful for anyone checking a home blood pressure reading, and since every calculation runs directly in your browser, your numbers are never sent to a server.
How to use

FAQ
- What categories does this tool use?
- It uses six stages — normal, elevated, prehypertension, stage 1, stage 2, and hypertensive crisis — based on standard combinations of systolic and diastolic values.
- Can this replace a doctor's diagnosis?
- No. This tool only provides a reference classification and is not a medical diagnosis. Consult a healthcare professional if your readings are consistently abnormal.
- Is my blood pressure data saved anywhere?
- No, nothing is stored. All calculations happen locally in your browser and nothing is sent to a server.
