How it works

Measure as usual.
Take a photo. Done.

You measure with your own blood pressure monitor, upper arm or wrist, just as before. Blutdruck-Tracker reads the values from its digital display and keeps your log.

  1. 1 · Measure

    As usual, with your own monitor. The app itself does not measure anything.

  2. 2 · Photograph

    Take a photo of the display with your iPhone. Systolic, diastolic and pulse are recognized.

  3. 3 · Check & save

    Quickly compare the values with the display and save. Ready for calendar, statistics and PDF.

01 · Log

A photo instead of typing.

Photograph the display of your blood pressure monitor. The app reads systolic, diastolic and pulse and pre-fills them for you. You check the values and save.

Note: The app does not measure blood pressure or pulse. It takes values from the display of your separate blood pressure monitor. Automatic recognition can make mistakes: compare every suggested value with the device display.

  • Manual entry works just as well: enter three numbers, done.
  • Afterwards, too: date and time can be adjusted freely.
  • When in doubt, empty rather than wrong: with reflections or deep shadow, a field stays empty rather than showing a wrong value.

02 · Overview

Every day at a glance.

The calendar shows the median for each day. One tap opens the day’s readings, with the option to add more right away.

  • Forgot a reading? You can add it at any time.
  • Thumbnail photo of the display in the day list, editing and deleting included.

03 · Statistics

The median. Not an average of averages.

For week, month, year and all time, the median is calculated separately for systolic, diastolic and pulse from all individual readings. Outliers distort the picture less than with an average.

  • Drill-down: from the year into the month, into the week, down to a single reading.

04 · Share

Ready for the doctor in seconds.

There is a PDF export for every view: day, week, month, year or everything. A clear A4 table with date, time and values, via mail, message, AirDrop or “Files”.

05 · Private

Your data belongs to you.

Your readings and photos are stored locally on your device. The app does not transmit them to us or to any server automatically. Only if you share a PDF export yourself or send a device report, the content you approve goes to the recipients you choose. No account, no ads, no data collection.

  • The camera is only used for photos of the device display.
  • Photo selection uses the iOS system picker: the app sees only the image you choose.

06 · Languages

Nine languages. Your choice.

German, English, Spanish, French, Italian, Portuguese (Brazil), Dutch, Polish and Turkish. You choose the language on first launch and can change it any time under “Settings”, without restarting.

Good to know

Does it work with your device?

1

Standard display: no setup

Recognition is designed for displays with SYS, DIA and PUL stacked and large segment digits. The app usually recognizes such devices without any setup.

2

Another device? Set it up yourself.

Mark on a photo where systolic, diastolic and pulse are. The app immediately tests whether it can read there. Works with segment-digit displays.

3

Or send a photo to the developer

Send a photo of the display straight from the app so your device can be supported in an upcoming version. You see the e-mail before it is sent. Every submission is reviewed. We add as many devices as possible in upcoming updates.

Developed with a reference device

Blutdruck-Tracker was developed and tested with an upper-arm monitor that has a classic segment display, with systolic, diastolic and pulse stacked. The app usually recognizes devices with a comparable display without any setup. During the free launch phase we want to find out whether setting up a device in the app is enough for other monitors, or whether we need further reference devices. Your feedback and the photos you send help us with that.

Manual entry works with any device, at any time. Recognized values are always a suggestion that you confirm or correct before saving.
