Six ways the CardioCall looks after you — day and night, in numbers big enough to read at arm’s length.
Record a personal ECG right from your wrist for a wellness snapshot you can review in the app.
Answer and make calls straight from the watch over Bluetooth 5.3 — your phone can stay in your bag.
On-demand blood-oxygen readings alongside continuous heart-rate tracking.
Wrist body-temperature readings help you keep an eye on how you are doing day to day.
Scientific sleep monitoring and stress readings show how your rest and pressure track together.
A crisp 1.56-inch 480×480 AMOLED in an IP67 water-resistant body, with a huge choice of faces.
The CardioCall keeps continuous tabs on the numbers that matter — heart rate around the clock, blood oxygen on demand, body temperature, sleep and stress — all gathered in the free H Band app so you can watch the trends that shape how you feel.
Rest your finger on the CardioCall and it records a personal ECG right there on your wrist — a quick wellness snapshot you can save and review in the app. It is built for everyday reference, not medical diagnosis, so it is an easy way to stay in tune with your body.
Wear the CardioCall to bed and it breaks your night into stages, then pairs that with all-day stress readings so you can see how recovery and pressure move together — the quiet signals behind how you feel each morning.
Bluetooth 5.3 calling connects the CardioCall to your phone and syncs your contacts, so you can answer or hang up with a tap — through the watch speaker and mic — whether you are cooking, driving or mid-workout.
