How it works
Three simple steps to a useful blood pressure log.
From your first reading to your next appointment. BpBook keeps the details together, with Mochi along for the everyday.
Snap a photo of your monitor or type your numbers. Check the reading, add a note, and save it to your diary.
Check the reading
Compare each number with your monitor before saving.
- Systolic
- 117mmHg
- Diastolic
- 81mmHg
- Pulse
- 56bpm
Blood pressure monitor scanner
Scan your blood pressure monitor instead of typing.
Take a photo of your monitor's screen and BpBook fills in the reading for you to check.
Take or upload a photo
Photograph the display straight on, without glare.
Review the numbers
Compare systolic, diastolic and pulse with your monitor and correct anything that looks wrong.
Confirm and save
The reading joins your diary with its date and time.
Photos are read in your browser and are not saved. Scanning can misread some displays, so you always confirm the numbers. Prefer typing? Manual entry is one tap away.

Frequently asked questions
Straight answers about tracking, scanning and sharing your readings.
What is BpBook?
BpBook is a free online blood pressure diary. You record systolic, diastolic and pulse readings, follow them on charts, and create reports to share with your doctor. It is a personal record, not a medical device, and it does not diagnose or treat any condition.
How do I track my blood pressure online?
Create a free account, then add each reading after you measure. Type the numbers or take a photo of your monitor. BpBook saves the date and time, keeps your history in order, and charts your readings as they build up.
How to measure blood pressure at homeCan I record blood pressure readings without an app?
Yes. BpBook runs in the web browser on your phone, tablet or computer, so there is nothing to install. If you would rather use paper or a spreadsheet, the free blood pressure log has printable and Excel versions that work without an account.
Free blood pressure logCan I scan my blood pressure monitor?
Yes. Take or choose a clear photo of the monitor screen and BpBook reads the systolic and diastolic numbers, and the pulse when it can. The photo is read in your browser and is not saved to your diary. Glare, angle and display style can cause mistakes, so check every number against your monitor before saving. You can always type a reading instead.
How monitor scanning worksCan I share my readings with my doctor?
Yes. You can download a PDF report, export your readings as a CSV file, or create a private read-only link that expires after 30 days. You choose whether notes are included in the link, and you can turn it off at any time.
How to share readings with your doctorCan I download a blood pressure report?
Yes. Choose a date range and download a PDF with your overall, morning and evening averages, a chart, and optionally every original reading. A CSV download is also available. Without an account, the free report generator creates a similar PDF from readings you paste in.
Free blood pressure report generatorIs BpBook free?
Yes. The diary, charts, monitor scanning, reports and exports are free to use, and so are the tools on this site. You only need a free account to save readings to a diary.
Can I use BpBook on my phone?
Yes. BpBook works in the browser on iPhone and Android phones, and you can add it to your home screen so it opens like an app. A dedicated mobile app is coming soon. It is not available in the App Store or Google Play yet.
Why is tracking blood pressure over time useful?
Blood pressure changes throughout the day and from day to day, so a single reading says little on its own. Heart health organisations recommend home monitoring because readings taken at consistent times give you and your clinician a fuller picture than occasional clinic visits. BpBook keeps that record organised. Your clinician interprets it.
