Frequently Asked Questions
What blood pressure reading is considered normal?
According to the ACC/AHA, a normal reading is systolic below 120 mm Hg AND diastolic below 80 mm Hg. Readings above this, even slightly, should be monitored and discussed with a doctor.
Why is my home reading different from the doctor's clinic?
White‑coat hypertension can raise readings in a clinical setting due to anxiety. Home measurements, taken after sitting quietly for five minutes, often give a more accurate picture of your daily blood pressure.
What should I do if I get a high reading?
Take a second reading after resting for a few minutes. If it remains high and you are not experiencing symptoms like chest pain or severe headache, schedule an appointment with your doctor. A hypertensive crisis (>180/>120) warrants urgent medical attention.
Is Blood Pressure Checker free and private?
Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
