What the diary does
An online blood pressure diary that works in any browser like a simple BP app — nothing to install — and prepares a clear report when you choose.
- Record systolic and diastolic pressure, heart rate, and a comment — two numbers and Save, with large readable text designed for phones.
- On your phone, photograph your monitor's screen and the numbers fill in for you. You check them, then press Save.
- See your trend chart with your home target line, plus 7-day and 30-day averages.
- Enter the target your own doctor gave you (the general home guide of below 135/85 is used until you do).
- Each reading is labelled “Within your target” or “Above your target” — a description of your own numbers, never a diagnosis or medical advice.
- Download a PDF report or a spreadsheet whenever you choose, for the period you choose.
Photograph your monitor instead of typing
On a phone, the entry card has a Take a photo of your monitor button. Point the camera at the monitor's screen and the systolic, diastolic and heart rate fields fill in for you.
- Nothing is saved until you check the numbers against your screen and press Save — the photo only fills the form.
- A digit the photo can't read clearly is left blank for you to type, never guessed.
- The photo is used once to read the digits and then discarded. It is never stored, and your name and diary are not sent with it — how the photo is handled.
- Prefer typing? The fields are right underneath, and the photo button is entirely optional.
Adding a reading takes about ten seconds — or one photo.
The report your doctor actually wants
Instead of scraps of paper or scrolling through a phone at your appointment, the PDF report shows your average and your last-seven-days average, your highest and lowest readings with dates, morning versus afternoon and evening averages, the share of readings below your home target, your average heart rate if you record it, a trend chart with your target lines, and the full record — all on a couple of tidy pages.
You choose the period it covers — the last two weeks, 30 or 90 days, or everything — then print it or email it to the practice yourself. Your diary always keeps every reading.
Your latest reading, your averages, and the report — illustrative numbers.

Common questions
What do I need to sign up?
Just a working email address. We don't ask for your name, date of birth or phone number.
Can my doctor log in and see my readings?
No — there is no doctor login or clinic dashboard. Only you can see your diary. Your readings reach your doctor when you give them a report.
Can I photograph my monitor instead of typing the numbers?
Yes, on a phone. Tap Take a photo of your monitor on the entry card and the numbers fill in for you. Check them against your screen before you press Save — the photo never saves anything by itself, and Health Diary never stores it (how the photo is handled).
How often should I record my blood pressure?
That's a question for your own doctor, since it depends on your situation. The diary works equally well for twice-daily readings or an occasional check.
Do I need a special blood pressure monitor?
Any home monitor works — you type in the numbers it shows, or photograph its screen. Most doctors suggest a validated upper-arm cuff monitor; ask your GP or pharmacist.
Can I keep my medication list here too?
Yes. The same sign-in gives you a medication list: the medicines you take, in your own words, with a one-page PDF to hand to your doctor and optional email reminders for medicines you take weekly or less often, or for an injection or appointment date.
Does it work on my phone?
Yes — it runs in the browser on any phone, tablet or computer, and you can add it to your home screen so it opens like an app.
