Your Health, In Living Colour.
Nova puts a 24/7 smart watch heart rate sensor behind a screen you will actually enjoy reading. The Nova keeps heart rate, sleep and daily activity on a bright full-colour display — and adds Bluetooth calls and an AI voice assistant, so the phone can stay in your pocket.
✓ Free shipping ✓ 30-day money-back guarantee ✓ Works with iPhone & Android
Every feature below is verified against the manufacturer’s spec sheet — no asterisks, no fine print.
Continuous tracking with a clear on-watch readout, charted over time in the app.
Follow professional coaching cues on screen and let live heart rate keep the effort honest.
Nova watches the night and reports how you actually slept, every morning.
Answer or dial calls straight from your wrist over rock-steady Bluetooth.
Speak commands and fire the camera shutter remotely — hands stay free.
IP68 dust and splash protection, alloy case, magnetic charging.
No menus, no fuss — your heart rate lives right on the bright home screen. Nova tracks it continuously and turns weeks of beats into trends you can actually read.
The Nova comes with professional sports guidance built in: pick your activity, follow the on-screen cues, and let real-time heart-rate tracking keep the effort honest. Every session lands in the app, charted next to your sleep and recovery.
Wear it to bed and Nova quietly writes the story of your night — how long, how deep, how restless — and files it in the app before your alarm goes off.
Designed for awareness and conversation with your physician — not for diagnosis.
Beyond heart rate, Nova monitors blood oxygen automatically around the clock and reads stress through heart-rate variability — with guided breathing exercises to bring it back down. In the Runmefit app, women’s health tools intelligently predict menstrual cycles, fertile periods and ovulation days. For wellness awareness, not medical diagnosis.
Take the call without touching your phone. Nova answers, dials and reminds — with Bluetooth keeping the line steady while your hands stay where they belong.
The AI voice assistant takes dictation while your hands are full, and the remote shutter grabs the group photo — all from your wrist.
Rain on the school run, dust in the garden, splashes at the sink — the alloy-cased, IP68-rated Nova takes the week as it comes and clicks back onto its magnetic charger when it’s done.

The sensor on the back of the watch is doing something quite simple, and understanding it explains every quirk you will notice.
An optical heart rate sensor shines green LEDs into the skin and measures how much light comes back. Blood absorbs green light, so each pulse changes the reflection, and the watch counts those changes. That is the whole mechanism — which is why fit, skin contact and movement all affect it so much.
At rest and at steady effort, a well-fitted wrist sensor tracks closely with a chest strap. Where it struggles is sudden change — the first seconds of a sprint, or short intervals — because the optical signal needs a moment to settle. The American Heart Association target heart rate guide gives the zones worth training to.
Snug, a finger width above the wrist bone, on dry skin. Loose, and the sensor loses contact as you move and fills the gaps with estimates. Tattoos, very cold hands and poor circulation all reduce the signal too, which is a property of the physics rather than a fault.
Not today’s figure — the trend across weeks. That is only possible if the watch stays on overnight, which is why battery life and comfort matter as much as the sensor itself. Nova is designed to run for weeks rather than days.
Voice features run through the paired phone and its data connection, so they work in town and stop at the edge of coverage. The sensors carry on regardless. More in what a watch assistant can actually do and how Bluetooth calling works. The CDC activity guidelines are a better daily target than any score.

It shines green LEDs into your skin and measures how much light bounces back. Blood absorbs green light, so every heartbeat changes the reflection slightly, and the watch counts those changes to derive a rate. Because it depends on light reaching blood vessels and returning cleanly, anything that breaks skin contact — a loose strap, movement, very cold hands — degrades the reading.
Two reasons, usually. Movement shifts the sensor against your skin, which introduces noise the watch has to filter out, and the optical signal takes a moment to catch up with a sudden change in effort. Tightening the strap one notch before a workout and wearing the watch slightly higher up the forearm solves most of it. For hard interval sessions, a chest strap remains more responsive.
Yes — the Nova connects to iPhones and Android phones through the free Runmefit app over Bluetooth. Calls, notifications and health syncing work on both.
No. Everything the Nova does — heart rate, sleep, calls, the voice assistant — is included in the price, permanently.
Yes. Answer, reject or dial calls straight from the wrist. You can also feel call and message reminders when your phone is buried in a bag.
Wake it on the watch, speak, and it handles commands hands-free — handy while cooking or driving. It works alongside the remote camera shutter.
The Nova is IP68 rated: sweat, rain and hand-washing splashes are fine, but keep it out of the pool and shower.
Wear it for a full month. If it hasn’t earned its place, our 30-day money-back guarantee refunds you in full — no restocking fee, no fuss.
