BP Log: Blood Pressure Diary

Asked to keep a record of your blood pressure before your next appointment?

BP Log is the diary for it. Take your reading on your own blood pressure monitor, type in the three numbers, and it keeps them in order, works out your averages, and turns the whole lot into a clean PDF you can print or send to your doctor.

It replaces the paper blood pressure log book — and the log sheet your doctor asked for becomes a PDF instead of a page you have to remember to bring.

WHO IT IS FOR
Anyone whose doctor or nurse asked for a week or two of readings before an appointment. Anyone starting or changing tablets for hypertension and keeping a record of what happens next. Anyone who has kept a paper log book for years and would rather not lose it in a drawer. And anyone keeping a journal for a parent or a partner as well as for themselves.

BUILT TO BE READ EASILY
The numbers are big. The keypad is big. If that still isn't enough, the large print scales up again, and there are high-contrast colours for tired eyes. Most blood pressure apps are built for a phone screen; this one is built for the person reading it. There is no tiny text to squint at and nothing hidden behind a gesture you have to know about.

LOG A READING IN SECONDS
Tap in the top number (systolic), the bottom number (diastolic) and your pulse. The keypad moves you along automatically, so a normal reading is nine taps and done. Morning and evening are tagged for you. Add a note if something was different — before your tablets, after a walk, sitting or lying down.

MORNING AND EVENING REMINDERS
Twice a day, at times you choose. Reminders live on your phone, and they never comment on a reading. Set them for the times your doctor asked about — first thing, before your tablets, or last thing at night — and turn them off again whenever you like.

SEE THE PATTERN
Your readings, charted. Mornings and evenings side by side, week by week, so you can see what your numbers actually do between appointments — not just the one taken in the waiting room. A blood pressure tracker is only useful if you can read the trend at a glance, so the chart is drawn large and plain, from your own entries and nothing else.

THE REPORT YOUR DOCTOR ASKED FOR
Every reading in your chosen range, with the date, the time and your notes, and your averages at the end. Print it, email it, or hand it over on your phone. 7, 30 and 90-day ranges. It is laid out the way a paper record is laid out, so nobody has to work out how to read it.

TWO PEOPLE, ONE APP
Keep a separate diary for your spouse. Separate readings, separate averages, separate report. Nothing is mixed together and nothing is shared between them.

YOUR READINGS STAY ON YOUR PHONE
No account. No sign-in. No server. It works with aeroplane mode on, and nothing you enter is uploaded anywhere. A report or an export leaves your phone only when you choose to share it. No ads, ever.

ALSO INSIDE
• 7 and 30-day averages
• Reference ranges published by the ACC/AHA (2017), shown as reference — never as an assessment
• Tags for what was happening around a reading, and a note when you want one
• CSV export, backup and restore
• Light and dark, following your phone

BP Log is a manual logging diary, not a medical device. It does not measure blood pressure and does not provide medical advice. You take your readings on your own monitor and enter them yourself.
