Doctor said to track your blood pressure?
Systo turns it into a five-second habit — and gives you a clear, one-page report for your next visit.
Download on the App StoreSysto doesn’t measure blood pressure. Use it with any validated cuff.

Tracking blood pressure shouldn’t feel like homework.
Numbers scribbled on the back of an envelope.
“What’s your average?” — and you have no idea.
One high reading, and you worry all day.
How it works
Measure
Use the cuff you already have, the way your doctor showed you.

Log or scan
Type three numbers with big keys — or point your camera at the cuff.

Share
Send a one-page PDF to your doctor, or print it before your visit.

Every reading lands on one simple bar
The same colours your doctor uses. Choose US (AHA) or European (ESC) guidelines in Settings.
Made to be simple
Systo turns it into a five-second habit — and gives you a clear, one-page report for your next visit.
Your real trend
Single readings jump around. Systo shows the weekly average your doctor looks at.

Scan your cuff
Point your camera at the monitor. Systo reads the numbers on your iPhone — the photo is never saved.
No more notes on paper
Every reading is saved with the time, arm and whether you’d taken your medication.
Plain words
Each reading is explained in everyday language, with the colour range from the guidelines.
Gentle reminders
Morning and evening nudges so measuring becomes a routine.
See what moves your numbers
Tag coffee, salt, stress or poor sleep, and see how they change your top number.
After a check-up
Your doctor asked for two weeks of home readings.
On medication
See whether your numbers settle, before and after your pills.
Caring for a parent
Keep their readings in one place and bring them to the appointment.

Questions
Does Systo measure my blood pressure?
No. No app can measure blood pressure with an iPhone camera or finger. Measure with a validated cuff, then log the numbers in Systo.
Which monitors does it work with?
Any upper-arm or wrist monitor. You type the numbers, or scan the display with your camera.
Can I share the results with my doctor?
Yes. Pick a period and Systo creates a one-page PDF with your averages, a chart and every reading.
Is it free?
Logging, history and reminders are free. Systo Pro adds PDF reports, cuff scanning and insights.
