Serious About Health. Stylish About It.
Syntra is a smartwatch with blood pressure monitor trends built into an always-on display you will not want to cover up. The Syntra pairs a bold 1.73-inch always-on AMOLED with round-the-clock heart, blood pressure, oxygen and sleep tracking — plus Bluetooth calls from your wrist and a battery that runs 7–10 days between charges.
✓ Free shipping ✓ 30-day money-back guarantee ✓ Works with iPhone & Android
Six tools that quietly work all day, behind a watch face you’ll actually want to wear.
Round-the-clock tracking that nudges you when your numbers wander off course.
A few seconds against your wrist and your oxygen saturation is on screen.
Guided breathing sessions to slow a racing day back down.
Answer and make calls straight from the watch — phone stays in your pocket.
Your night mapped automatically — depth, duration and disturbances.
A two-hour magnetic charge runs the better part of two weeks.
Energy dips, restless nights and a heart that races on the stairs all leave traces. The Syntra logs them quietly in the background, so you argue with data instead of guessing — and change habits before they change you.
No cuff, no pharmacy queue, no waiting room. Glance at your wrist with your morning coffee and your reading is logged — building a history your doctor can actually work with.
For wellness tracking and awareness — not a replacement for a medical blood pressure monitor.
Check your blood oxygen whenever you like, then let the guided breathing sessions walk you back to calm — slow inhales, slow exhales, measurable results on a screen big enough to follow.
Designed for awareness and conversation with your physician — not for diagnosis.
Wear it to bed and wake up to the whole story — how long you slept, how deep it went, and how tonight stacked up against the rest of the week. Fixing sleep starts with seeing it.
Walking the dog, carrying shopping, elbow-deep in the garden — when the phone rings, just talk to your watch. Built-in speaker and mic keep the conversation going while your hands stay busy.
For the parent who never mentions the dizzy spells or the partner who skips check-ups: a watch they’ll wear for the style, that quietly keeps their heart, pressure and sleep on record.

Wrist blood-pressure figures are estimates, and they are useful precisely when you treat them as estimates. Here is how.
Syntra reads the pulse waveform optically at your wrist and derives a systolic and diastolic figure from its shape. A cuff measures pressure directly by squeezing an artery. Those are fundamentally different methods, which is why the numbers will not always agree — and why the watch is a pattern tool rather than a measurement one. See how cuffless estimation works.
The National Heart, Lung, and Blood Institute and the American Heart Association guide to blood pressure readings publish the same ranges. Use those as the reference and the watch to see how your own numbers move between them across a week.
This is the important sentence on the page. A smartwatch blood-pressure figure is not a substitute for a validated upper-arm cuff, and no decision about medication, treatment or a GP visit should rest on a wrist estimate. Our guide to blood pressure smartwatch accuracy sets out how large the gap can be.
What a watch can do that a cuff cannot is keep reading while you sleep and while you go about the day. That continuous picture is genuinely new information — 24-hour blood pressure monitoring explains why those windows matter.
Snug, a finger width above the wrist bone, arm still and supported at heart height while a reading is taken. A loose watch on a moving arm produces a number, but not a meaningful one. Battery matters here too — see what continuous tracking costs.

It is an estimate rather than a measurement, and the honest answer is that it varies. The watch infers pressure from the shape of your pulse waveform, so fit, movement, circulation and skin temperature all affect it, and readings can differ noticeably from a cuff taken at the same moment. What it does well is show you how your own numbers move across a week, including overnight, which a cuff cannot. Keep a validated upper-arm cuff for anything you would act on.
No, and you should not try. A validated upper-arm cuff measures pressure directly and is what clinical decisions are based on. Syntra estimates optically from the wrist, which is useful for spotting patterns and trends between cuff readings but not for establishing a number you would act on. Use them together — the watch for the pattern, the cuff for the answer.
Android 4.4+ and iOS 10+ over Bluetooth. The free FitCloudPro companion app stores your readings, sleep reports and trends.
Never. Heart rate, blood pressure, SpO₂, sleep, calling and breathing training are all included, free for life.
Treat them as a wellness companion — excellent for spotting trends and starting conversations with your doctor, not a replacement for medical equipment.
The watch pairs with your phone and uses its own speaker and microphone, so you can answer, talk and hang up without touching the phone.
7–10 days of normal use per charge, with up to 40 days on standby. A full magnetic charge takes about 2 hours, and IP68 water resistance handles rain, sweat and hand-washing.
You have 30 days and a full money-back guarantee, with free tracked shipping both ways on qualifying returns.
