What is Blood Pressure Logger?

The Blood Pressure Logger lets you record and track your blood pressure readings over time. This free tool helps you monitor systolic, diastolic, and pulse values — all health data stays private on your device.

Each entry takes systolic, diastolic, and pulse, then classifies the reading against the standard ACC/AHA stages (Normal, Elevated, Stage 1, Stage 2, Crisis). The trend chart plots up to the last 30 readings so you can spot whether your morning numbers drift, and a one-click CSV export lets you hand the log to a doctor.

How to use

1. Enter your systolic and diastolic pressure readings
2. Optionally add your pulse rate and any notes
3. View your history and track trends over time

When to use

• Tracking morning and evening readings after a doctor adjusts your dosage.
• Building a 7-day log before an appointment so the doctor sees real data instead of one office reading.
• Watching pulse alongside pressure during a new exercise routine.

Result

Log a reading of 120/80 mmHg with a pulse of 72 bpm and track how it changes weekly.

FAQ

Where does the logger save my readings?

Readings live in local storage on the device you used to enter them. They survive page reloads and tab closures but stay on that machine only. Clearing site data or using private mode wipes the history.

How does the tool classify the readings?

It uses the 2017 ACC/AHA thresholds: Normal under 120/80, Elevated 120-129 systolic with diastolic under 80, Stage 1 starts at 130/80, Stage 2 at 140/90, and Crisis at 180/120. The higher of the two numbers decides the stage.

Can I move my data to another phone or computer?

Yes. Export the log as CSV from the current device, then open the CSV in any spreadsheet on the new device. There is no cloud sync because we never store readings on a server.

Should I always trust the stage label?

The classification follows published thresholds, but a single reading is never a diagnosis. Doctors look at trends across multiple days and also factor age, medication, and other conditions. Use the labels as context, not as medical advice.

What is a realistic range for the inputs?

The form accepts systolic 50-300, diastolic 20-200, and pulse 20-250. Anything outside that is rejected as a typo. If your real reading is outside this range, that itself is a reason to call a clinician.
