Want a daily health monitoring watch with ECG built in, rather than just heart rate and blood oxygen? Among REXQU’s four daily health monitoring models, only one adds an on-demand ECG trace to the mix — here’s what that actually gets you, and how it compares to the rest of the lineup.
This article is for general information only and isn’t medical advice. An on-wrist ECG is a wellness and awareness tool, not a diagnostic device — share anything unusual with your doctor.
REXQU’s Daily Health Monitoring Lineup: Who Has ECG?
REXQU sells four watches built around continuous daily health tracking, and only the HealthLink includes ECG. Here’s how the full lineup compares.
| Model | ECG | Display | Standout | Price |
|---|---|---|---|---|
| REXQU HealthLink | Yes — on-demand | 1.95″ AMOLED | ECG plus body temperature | $139.97 |
| REXQU VitaSync | No | 1.83″ display | 100+ sport modes | $139.97 |
| REXQU OmniTrack | No | 1.93″ AMOLED, 800 nits | Brightest screen, stress tracking | $139.97 |
| REXQU BioTrack Pro | No | 1.96″ curved | One-handed clasp, big digits | $139.97 |
How the HealthLink’s Daily Health Monitoring Watch With ECG Works
Pressing the HealthLink’s side sensor for about 30 seconds records a single-lead electrocardiogram trace, the same basic technology used in consumer ECG features on other wearables. The reading, along with heart rate, blood oxygen, body temperature, breathing and sleep data, saves automatically to the companion app so you can review it later or show it to a doctor.
Research on consumer ECG wearables backs up why this matters as a screening tool: a 2024 analysis from the American College of Cardiology found that consumer smartwatch ECG features show high sensitivity and specificity for irregular rhythm detection, though they’re best used as an early flag rather than a clinical diagnosis. That’s exactly how REXQU frames the HealthLink’s ECG — a way to capture a snapshot when something feels off, not a replacement for a professional exam.
Do You Actually Need a Daily Health Monitoring Watch With ECG?
If you or a family member has ever wanted a way to capture “that fluttery feeling” as an actual data point instead of a vague description at a doctor’s appointment, the HealthLink’s ECG is the differentiator that justifies picking it over the other three. Its IP68 water resistance and no-subscription companion app match the rest of the lineup, so you’re not giving up anything else to get the ECG feature.
If ECG isn’t a priority, the other three models cover the core daily basics — heart rate, blood oxygen and sleep — at the same $139.97 price point, just with different strengths: the VitaSync leans into sport modes, the OmniTrack has the brightest outdoor-readable screen, and the BioTrack Pro’s one-handed clasp is built for easy day-to-day wear.
Frequently Asked Questions
How long does an ECG reading take on the HealthLink? About 30 seconds — press the side sensor and hold still until the trace completes, then it saves automatically to the app.
Is the ECG feature locked behind a subscription? No — ECG, along with every other tracking feature on the HealthLink, is included with the free companion app and no subscription tier.
Can I export the ECG trace to share with a doctor? Yes — the HealthLink’s companion app stores a history of past ECG recordings, and you can pull up or screenshot any individual trace to bring to an appointment rather than trying to describe symptoms from memory.
All four watches link back to REXQU’s daily health monitoring lineup, alongside the dedicated blood pressure smartwatches for anyone who wants pressure tracking specifically. For most shoppers weighing a daily health monitoring watch with ECG against the rest of REXQU’s lineup, the decision comes down to one question: do you want that extra heart-rhythm snapshot, or would you rather have brighter screens and sport modes instead?
