Looking for an automatic health monitoring watch that logs your vitals in the background instead of one you have to remember to check? REXQU sells two very different approaches to daily heart-health tracking: one that runs blood pressure checks around the clock on its own, and one built around a fast, deliberate 30-second reading. Here’s how they actually differ.
This article is for general information only and isn’t medical advice. REXQU watches are wellness devices, not medical devices — talk to a doctor about any health concerns.
What Makes a Watch an Automatic Health Monitoring Watch
Most wrist-based health trackers ask you to press a button or hold still for a reading. A true automatic health monitoring watch instead measures continuously in the background, so the data is already there by the time you open the app — no ritual, no remembering to check in.
REXQU BioVision: 24-Hour Automatic Blood Pressure
The REXQU BioVision ($149.97) is built around exactly that idea. Its FitBlood+PWTT algorithm measures blood pressure automatically, 24 hours a day, with no cuff and no manual trigger required — readings simply accumulate into the app as the day goes on. BioVision pairs that with on-wrist ECG (a roughly 60-second recording when you want a full waveform), SpO₂ and body-temperature sensing, body composition estimates, sleep staging down to REM, Bluetooth calls, one-click SOS and 60+ sport modes on a 1.81″ HD display.
REXQU VitaCore: The 30-Second On-Demand Check
The REXQU VitaCore ($149.97) takes the opposite approach: press the rotating crown and it captures heart rate, blood pressure, blood oxygen, body temperature and stress in a single 30-second check, with the results and an HRV heart-health index shown right away. It can also log trends quietly through the day, but the headline feature is a fast, complete reading on demand rather than continuous background monitoring — on a 2.04″ always-on AMOLED with a week of battery life, Bluetooth calls, SOS and NFC.
| Feature | REXQU BioVision | REXQU VitaCore |
|---|---|---|
| Price | $149.97 | $149.97 |
| Blood pressure monitoring | Automatic, 24-hour background | On-demand 30-second check |
| ECG | Yes, ~60-second recording | Yes, via rotating crown |
| Body temperature | Yes, NTC thermal sensor | Yes |
| Body composition | Yes (BMI, body fat, muscle, hydration) | Not listed |
| Display | 1.81″ HD | 2.04″ always-on AMOLED |
| Battery life | 7–10 days | 5–10 days |

Automatic vs On-Demand: Which Should You Buy?
If you want your blood pressure and heart data collected without thinking about it — useful for spotting patterns across mornings, evenings, workdays and weekends — the BioVision’s always-on approach does the work passively. It’s also the stronger pick if body composition metrics matter to you, since VitaCore doesn’t track those.
If you’d rather take a quick, deliberate reading and see everything at once — heart rate, blood pressure, oxygen, temperature and stress in one 30-second check — VitaCore’s rotating-crown workflow and always-on display make that a faster, more visible habit to build.
FAQ: Automatic Health Monitoring Watches
Is automatic blood pressure monitoring more accurate than on-demand checks? Both use the same underlying wrist-based optical sensing technology; automatic monitoring simply takes more readings across the day, which can reveal patterns a single check might miss. Neither replaces a clinical blood pressure monitor for medical decisions — see the American Heart Association’s guidance on home blood pressure monitoring for how to use any wrist or cuff device correctly.
Does automatic monitoring drain the battery faster? BioVision still rates 7–10 days per charge despite the background monitoring, comparable to VitaCore’s 5–10 days, since the sensors involved sip relatively little power compared to a display or GPS radio.
Can I still get an on-demand reading from an automatic health monitoring watch? Yes — BioVision supports spot-checks on top of its background monitoring, so you’re not limited to waiting for the next automatic reading.
Bottom Line
Both watches are genuine picks for an automatic health monitoring watch lineup, but they solve the problem differently: BioVision runs blood pressure checks continuously in the background, while VitaCore packages a complete health snapshot into one fast, on-demand check.
