User environment
Let’s put our phone aside for a moment and check the UI on the watch itself.

We can quickly access the watch’s key features by swiping left or right to access fitness data (estimated distance and calories burned, plus steps), latest blood pressure readings, heart rate data, and Sp02 percentage (aka oxygen saturation) .

BP is clearly the blood pressure monitor feature with a default mode that syncs with the mobile app to keep a history of readings, and a guest mode in case you want to take a friend or family number reading and not mess with your own data . I’ll go into more details about blood pressure function in another section below.

The SpO2 or oxygen saturation level would be normal at 95-100 percent. The data can be used to detect sleep apnea, and you may also recall that some COVID-19 patients had low levels. Taking a measurement is super easy: just go to the menu and wait a few seconds. Sorry I didn’t get COVID-19 during the assessment, so I just measured my SpO2 while I was healthy, and I always got 98%. It is worth noting that the smartwatch can detect sleep apnea and if the option is enabled, the watch will vibrate in that case.

The heart rate monitoring function works as expected, and I actually never had to manually activate it during normal use, as I enabled auto-measurement (Auto MEAS) so that it will automatically take readings every few minutes and sync the data in the app.

The training section comes with three options: Outdoor Walking, Indoor Running, and Outdoor Running.

If you don’t wear your watch while sleeping, you’ll only see “No sleep tracking”, but if you do, the watch tells you how long you’ve slept, how well with a sleep quality score, and splits light and deep periods .

HRV (Heart Rate Variability) is measured at night, so if you don’t wear the watch while sleeping, you’ll only see a black graph (top left), but if you do, you’ll see a data plot with red dots ( top right). That doesn’t tell us anything, but more details will be provided in the app. HRV measurements can help identify anomalies, and decreased HRV is associated with an increased risk of death and arrhythmias.

Two alerts are available: Apnea Alert and Move It. The first triggers if you suffer from sleep apnea, the second if you sit in your chair too long. As with the alarms, the watch vibrates and displays a visual reason for the alert.

The watch supports five languages: Simplified Chinese, Traditional Chinese, English, Japanese and Spanish. This subset of languages ​​can also affect your ability to read messages from your smartphone (eg SMS, Facebook Messenger, LINE, Whatsapp…) in an unsupported language. For example, the watch cannot display messages written in Thai language.

The Units feature allows you to select whether the distances are displayed in kilometers or miles and the temperature in Celsius or Fahrenheit. Reset deletes all data and restores the watch to factory settings.

Blood pressure measurement with BP Doctor PRO smartwatch
Let’s take a closer look at the blood pressure monitoring feature. But before dong, I took a reading with the Koogeek BP2 blood pressure monitor that uses a traditional inflatable arm cuff. SYS/DIA was 104/55 and heart rate was 61 beats per minute.

There are two ways to start the measurement, either through the menu as seen before, or by holding the Home button for two seconds, in which case the measurement will start automatically.

The air cuff will slowly inflate and feel progressively tighter on your wrist as the SYS number goes up, and once the measurement is complete, which takes approximately 30 seconds, you will be given the SYS/DIA numbers in mmHg and your heart rate. I got 110/68 mmHg and 65 bpm, which isn’t that far off the 104/55 mmHg and 61 bpm numbers I got with the BP2 in that both results are still in the safe zone.

BP Doctor Plus Android App
While it is possible to use the watch without the app, after the initial setup you will get most of the analysis and health history from the BP Doctor app.

The main page has all the information for the current day on one page with blood pressure, SpO2, HRV, weight, exercise data, steps count, calories burned and sleep monitoring.

Battery Life of BP Doctor PRO
The smartwatch will not last as long as some others based on an e-paper display, and also because of the features like continuous HRM and blood pressure monitoring. In my case, I used the watch with maximum brightness, 20 seconds timeout, increase to wake, automatic HRM and I took one blood pressure reading per day. After charging the watch, which usually takes more than an hour from 10%, I could use it for 2.5 days, which practically means 3 days from Monday morning to Wednesday evening.

Conclusion
Overall, I’m satisfied with the watch, and it’s especially useful for people who need to regularly monitor vital health signs such as blood pressure, heart rate, oxygen saturation, and so on, without having to carry around larger devices.
