What Sistovia does
A simple tool for people who measure their blood pressure at home, whether on their own or because their doctor asked them to.
Quick entries
Record systolic and diastolic pressure, pulse and an optional note in a few taps.
Averages the guideline way
Readings are averaged using the home measurement method described in the European guideline.
Measurement reminders
Optional reminders help you complete a full measuring week.
A record for your doctor
A free PDF with your averages and every reading, ready to print or send.
Private by design
No server, no sign in, no analytics. Everything stays on your device and works without internet.
Five languages
The app interface, reports and dates adapt to the language you choose.
How a measuring week works
A single reading says little. Blood pressure changes through the day, so guidelines ask for a series of home readings and look at the average.
Example: the European method
Measure for 7 days, morning and evening.The first day is left out, because readings tend to run higher while you get used to measuring.
Choose your language
On first launch you pick the language and confirm that the app is a diary, not a medical device.
Record your readings
Enter each reading as you take it. Reminders help you keep the rhythm.
See your average
After the week, Sistovia shows your average next to the home measurement threshold of the guideline. What it means for you is up to your doctor.
Guideline used
Sistovia compares home readings with the ranges published by the European medical societies. It is available in the European Union.
| Region | Guideline | Home measurement threshold | Measuring period |
|---|---|---|---|
| Europe | ESC 2024, ESH 2023 | 135/85 mmHg | 7 days, first day skipped |
You can also enter a reference value your doctor gave you. The app then compares your readings with that value instead.
Notices in the app
Two notices are shown regardless of the reference value you use.
180/110
Very high reading. From this value the app suggests measuring again after rest, contacting your doctor, and shows the emergency number if you feel unwell.
90/60
Low reading. Below this value the app lets you know, so you can mention it to your doctor, especially if you feel dizzy or weak.
Records for your doctor
Created on your phone as a PDF. Nothing is uploaded anywhere.
Extended record
In preparationWe are working on a longer record for people who measure over several weeks. It is planned to include:
- Charts of your readings over time
- Morning and evening readings side by side
- Two periods compared, for example before and after a chosen date
- Weekly averages and readings by tag
- A calendar showing which days were measured
- Unusually high or low readings and your notes, listed separately

Questions
How should I measure at home?
Sit quietly for a few minutes before measuring, with your back supported and feet flat on the floor. Put the cuff on your bare upper arm at heart level. Do not smoke, drink coffee or exercise in the 30 minutes before. Use a validated automatic upper arm device and follow the instructions from your doctor if they differ.
Why is the first day left out?
On the first day people are often a little tense about measuring, and readings tend to be higher. The European guideline therefore skips it and average the following days.
Why is the home limit lower than the one at the doctor's office?
Readings at the doctor's office are usually higher than at home. Guidelines set separate, lower limits for home readings, which is why Sistovia only uses home thresholds.
Does Sistovia tell me whether I have high blood pressure?
No. Sistovia records your readings and shows how they compare with published guidelines. Only a doctor can assess your blood pressure and decide on any treatment. Never change your medication based on the app.
Where is my data stored?
Only on your phone. There is no account and no server, so we cannot see your readings. If you delete the app, the data is deleted too, so export a report if you want to keep a copy.
How much does it cost?
The app and the PDF record are free, with no ads and no account. An extended record is in preparation.
