Before you install

You bring the reading

BP Log records numbers from a home blood pressure monitor. It does not measure blood pressure.

Keep a usable record

Log readings, review the history and trends, and generate a PDF report for a clinician conversation.

Use on your phone

Works offline with no account needed; readings are stored on your device.

Reference, not diagnosis

Categories and trends organise what you record; they are not medical advice or a diagnosis. For decisions about your blood pressure, bring the report and your questions to your doctor or healthcare provider.

A clear record, step by step

⚡

Start with one reading

Enter systolic, diastolic, and pulse from your home monitor without a long setup flow.

🎨

See the reference category

Each recorded reading is classified as Normal, Elevated, Stage 1, Stage 2, or Crisis using American Heart Association guidelines.

📈

Review the record over time

See systolic and diastolic trends by week, month, three months, six months, or all time.

📊

Spot the pattern

View the distribution of your recorded categories in one chart before a conversation with your doctor.

📄

Prepare a doctor handoff

Generate a clean PDF of your readings to share at your next appointment.

⏰

Set your own reminder

Choose morning and evening reminders that fit the measurement plan you and your clinician use.

💡

Keep the focus on your record

Use the history and report as a factual starting point, not as a replacement for clinical guidance.

🔒

Private by design

Readings stay on your phone. No account or internet connection is needed for the core record.

Frequently Asked Questions

Is BP Log really free?

Yes. BP Log has no ads and nothing to buy inside it today. Logging, history, AHA classification, trends, and reminders are the core of the app and stay free. If we ever add extras, they will be a one-time purchase, never a subscription.

Does BP Log need internet access?

No. BP Log works completely offline. Your blood pressure data is stored only on your device and never uploaded to any server.

What is AHA blood pressure classification?

The American Heart Association (AHA) classifies blood pressure into categories: Normal (less than 120/80), Elevated (120-129 with diastolic below 80), High Blood Pressure Stage 1 (130-139 or 80-89), High Blood Pressure Stage 2 (140 or higher, or 90 or higher), and Hypertensive Crisis (systolic higher than 180 and/or diastolic higher than 120). BP Log automatically classifies each reading.

Can I share my BP readings with my doctor?

Yes. BP Log lets you export your readings as a PDF report that you can share with your doctor via WhatsApp, email, or print.

How often should I measure blood pressure at home?

Follow the schedule your clinician recommends. The American Heart Association advises using a validated automatic upper-arm monitor, measuring at the same time each day when possible, and taking two readings one minute apart.

Is my health data private?

Yes. BP Log stores all readings locally on your device only. There is no account and no cloud sync. It reports anonymous crash and usage statistics so we can fix problems, and that never includes your readings. Your health information never leaves your phone.

What Android version does BP Log require?

BP Log requires Android 8.0 (Oreo) or higher. It works on most Android phones released after 2017.

Can BP Log replace my doctor's advice?

No. BP Log is an informational tool for tracking readings. The AHA classification is for reference only and is not a medical diagnosis. Always consult your doctor for medical decisions.
