⚕️ This is a record-keeping tool, not medical advice. Category labels follow widely used clinical bands for context only — your doctor interprets your readings. If a reading is very high (180/110 or more) or you feel unwell, seek medical care promptly.
A single clinic reading is a snapshot taken on a possibly stressful day — some people measure higher at the doctor's ("white coat" effect) and others lower. A log of properly-taken home readings across days and times gives your GP the pattern they actually diagnose from, which is why the tool shows a rolling average of your recent readings: treatment decisions follow averages, not one-off spikes. Log the details in notes (which arm, after coffee, feeling stressed) — context explains outliers.
Use a validated upper-arm cuff, check its fit, and bring it to a GP visit occasionally to compare against theirs. Blood pressure travels with overall health, so the Weight Journal, Habit Tracker (walking, salt habits) and BMI Calculator are natural companions.
What do the category labels mean?
They follow the widely used clinical bands (optimal under 120/80 up to grade 3 at 180/110+), applying whichever of your two numbers falls in the higher band. They're context, not diagnosis — only your doctor can interpret readings for you.
Why are my readings different each time?
Blood pressure moves constantly with activity, stress, caffeine and time of day. That's normal — and it's exactly why the average across many correct readings is what matters.
Which arm should I use?
Whichever your doctor advises — commonly the arm that reads higher, used consistently. Note the arm in your first entries so the log is comparable.
When should a reading worry me?
If you get 180/110 or higher, rest a few minutes and re-measure; if it stays that high, or you have chest pain, severe headache, vision changes or breathlessness, seek urgent medical care. For anything persistently elevated, book your GP.
Is my health data private?
Yes — readings live only in this browser on this device and are never uploaded. Export the CSV to bring to appointments; it's also your backup.
