Blood Pressure Log & Pulse

Blood Pressure Log exists for one instruction, given across a desk in ninety seconds: take it twice a day for a week and bring me the numbers. You go home with a cuff, a scrap of paper, and no idea that the paper is the hard part. THE UNIT IS A SITTING, NOT A SINGLE READING Every home-monitoring instruction sheet says the same thing: sit still for five minutes, take two or three readings about a minute apart, and use the average. That is not fussiness. The first reading of a sitting is reliably the largest one in it, because the cuff inflating is itself a stimulus, and so is having just climbed the stairs. So an app storing one row per reading is not storing the measurement. It is storing the noise, and drawing it as a sawtooth. Here the sitting is the row: a date, a morning or evening slot, and the two or three readings you took within a few minutes of each other. The average is computed and never typed. And the number of readings behind it is shown wherever the average is shown, because an average of one is a different fact from an average of three. If you only had time for one reading, it still saves. A form that refuses is a form that gets replaced by the scrap of paper it was meant to retire. IT DOES NOT TELL YOU WHAT YOUR NUMBERS MEAN No colours. No categories. No arrows, no faces, no verdicts anywhere. This is the decision most likely to be mistaken for laziness, so here is the reasoning. Almost every app of this kind colour-codes a reading and puts a word beside it. It looks helpful, and it is a judgement passed by an app that measured nothing and knows nothing about you. This app records, it arranges, and it hands over. That is the whole job, and it does it properly. HANDING IT OVER IS THE POINT A spreadsheet file: one line per reading, with the sitting average beside it, the date, the slot, the arm and your note. Every number you typed is in there. And a plain written summary, arranged to be read out loud from a phone screen with no spreadsheet in the room. What will be sent is shown to you in full first. WHAT ELSE IS IN IT A log of every sitting, newest first, grouped by day. A chart over 7, 14, 30 or 90 days or over everything, one point per sitting. The average across any window, with the number of sittings behind it. Pulse recorded alongside, left empty when your monitor did not report one. Which arm, and a note, both optional and both blank until you say otherwise. Optional morning and evening reminders, off until you switch them on. A full backup file, so a new phone is not a fresh start. YOUR READINGS STAY ON YOUR PHONE No account. No sign-up. No server. Nothing is uploaded, ever. The readings are health information about you, they are stored only on this device, and the only way they leave is an export you perform yourself and name the file for. Android cloud backup is switched off. The app stays out of the recents screen and out of screenshots by default. Turn it off if you want to screenshot your own log; the setting says exactly that. There is no passcode and there will not be one: a PIN over a database any backup tool can read would be a promise this app cannot keep. Uninstalling deletes everything. Save a copy first: the backup is one file, and restoring it on a new phone puts the whole record back. WHAT IT IS NOT It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional for medical advice, diagnosis, or treatment. It does not track medication. No doses, nothing to tick off. It is not a scale, and there is no body measurement of any kind in here. It does not connect to a cuff, a wearable or a health platform. Every number here was typed by the person it belongs to, which is why it needs no sensor permission and no Bluetooth. Five permissions. Three are for the ads that keep it free; the other two are the optional reminders, never requested unless you switch one on.
