Trains With You. Watches Over You.
IntelliFit is a health monitor watch that checks in on you all day, not just when you ask. The IntelliFit pairs serious fitness tracking with a full health toolkit — on-demand ECG, heart rate, blood pressure, blood oxygen, body temperature and sleep — plus Bluetooth calls, one-button SOS and remote family care on a bright 1.91-inch HD display.
✓ Free shipping ✓ 30-day money-back guarantee ✓ Works with iPhone & Android
Six everyday health tools, one glance — and Bluetooth calls when your hands are busy.
Continuous tracking that taps you on the wrist when your numbers step out of line.
Record an electrocardiogram in moments and keep every trace filed for your doctor.
Check your oxygen saturation any time — one tap, a few seconds, full clarity.
A discreet skin-temperature sensor flags changes before you reach for the thermometer.
Light, deep and REM stages tracked automatically while you rest.
Answer calls from the wrist, trigger an SOS, and share your vitals with family through the app.

That afternoon slump, the racing pulse on a hill, the restless nights — they all leave fingerprints in your data. The IntelliFit gathers them quietly and shows you the pattern, so you can spot trends and build healthier habits.
No cuff on the shelf, no appointment, no rolling up your sleeve. Glance at your wrist over breakfast and your reading is there — logged, charted and ready to show your doctor at the next visit.
For wellness tracking and awareness — not a replacement for a medical blood pressure monitor.


Feel something odd? Press the sensor and the IntelliFit records an electrocardiogram in about half a minute, using the same electrical principle as clinic machines. The moment passes — the trace stays.
Designed for awareness and conversation with your physician — not for diagnosis.
Wear it to bed and wake to a full report: light, deep and REM sleep, overnight heart rate, and how tonight compared to last week. Once you can see your sleep, you can fix it.


Beyond the basics, the IntelliFit reads your blood oxygen on demand and keeps an eye on body temperature — plus breathing exercises when your stress numbers say you need a minute.

For families who like to stay connected: link the IntelliFit to the family-care feature in the app and see their heart rate, activity and daily vitals from wherever you are.

IntelliFit collects a lot of signals. Every one of them is a wellness estimate rather than a clinical measurement — here is how to read each properly.
Optical heart-rate sensing from the wrist is mature and, worn snugly, close to a chest strap at rest and steady effort. The American Heart Association target heart rate guide gives the ranges. Watch your own resting rate over weeks rather than reading anything into a single measurement.
IntelliFit records a short single-lead ECG from your wrist. That is not a clinical 12-lead ECG and it does not diagnose anything — it produces a trace you can keep and show to a clinician. Read our ECG smartwatch guide and what a smartwatch can and cannot say about AFib before you rely on it.
The watch estimates blood pressure optically rather than measuring it with a cuff. It is genuinely useful for seeing patterns across a week, and it is not a substitute for a validated upper-arm cuff. The National Heart, Lung, and Blood Institute has the reference ranges, and how cuffless estimation works explains the method.
Blood-oxygen estimates move with fit, motion, circulation and cold hands. Skin temperature is not core body temperature and cannot detect fever. Both are trend signals — compare them against your own normal, never against a threshold.
Sleep stages are inferred from movement and heart rate rather than measured. SOS sends an alert to contacts you set up in advance and depends on your phone, its network and its battery — it is not a monitored medical-alert service. The CDC activity guidelines are a better daily target than any score the watch invents. See also daily health monitoring.

No. IntelliFit is a wellness tracker. Its heart-rate, blood-pressure, blood-oxygen and temperature figures are estimates produced by optical sensors on the wrist, and they are designed to show you trends over time rather than to diagnose anything. They do not replace a validated blood-pressure cuff, a clinical ECG, or a conversation with a clinician about anything that concerns you.
Heart rate first, by some distance — it is the most mature wrist measurement and, worn snugly, it tracks well at rest and at steady effort. Sleep duration is next, though the stage breakdown is inferred rather than measured. Blood pressure and blood oxygen are the softest, because both are estimated optically and shift with fit, movement and circulation. Read all of them as your own baseline moving, not as absolute numbers.
Yes — iPhone (iOS 9+) and Android (4.4+) both work over Bluetooth. The free DeepFit companion app stores your readings, trends, sleep reports and ECG history.
Nothing. ECG, blood pressure, SpO₂, body temperature, sleep, Bluetooth calls, SOS and family care all come fully enabled, free forever.
Treat them as an early-warning companion. The IntelliFit is a wellness device — brilliant for spotting trends and prompting conversations with your doctor, but not a replacement for medical equipment.
Yes — a skin-temperature sensor tracks changes against your personal baseline, which is exactly how you catch a fever brewing early.
IP68 water resistance handles rain, sweat, hand-washing and everyday knocks — and a charge lasts 5–12 days of normal use, with 30+ days on standby.
