Blood Pressure Log & Chart

Type in the numbers your blood pressure monitor shows. The app keeps them, draws the chart, and makes the sheet you hand to your doctor.

■ It does not measure anything
No phone can measure blood pressure from a camera or a fingertip. This app does not pretend to. You read your own monitor, you type two numbers, and the app looks after the rest.

■ One tap to the keypad
Open the app, press Record, and the boxes are already there. The top and bottom numbers are all that is required. Everything else can stay empty.

■ Morning and evening, kept apart
Home readings are meant to be read as a morning average and an evening average, so that is how they are shown. Every entry is marked morning or evening, and the month shows both, next to the overall average.

■ Your chart
The month is drawn as two lines, the top number in red and the bottom one in blue, with your target line across it. The scale does not move from month to month, so a good month really does look different from a bad one.

■ PDF and CSV, free, every month
Export the month as a one-page sheet to print or hand over, or as a spreadsheet. There is no limit on how far back you can go, there is nothing to unlock, and the dates run down the page in the order you would expect.

■ Pulse, weight, temperature, SpO2
Turn on only the ones you use. They sit on the same screen as the blood pressure and they are all optional, so a day with only two numbers is still a complete day.

■ Fix anything later
Forgot to write one down? Add it with the right date and time. Open any entry to change a number, move it, or put a note on it.

■ Your records stay yours
Everything is kept on this phone. No account, no sign-in, no server, nothing uploaded. The app also keeps a spare copy of your records and a dated backup for the last seven days, and you can write the whole lot out to a file before you change phones.

■ The bands
Each reading is labelled with the usual published band, from normal up to grade 3, using the higher of the two numbers. It is a label, not a diagnosis.
