"OPPO Band Style" that can also measure blood oxygen levels in the 4000 yen range -Mobile Watch

　I tried using the smart band "OPPO Band Style" released by OPPO on April 23.Oppo provided "Please try", and I intend to use it for about a week, but I have been using it for about three weeks.In other words, I really like it.

　The actual selling price of OPPO Band Style is 4480 yen.It's cheap.However, it has a variety of functions like a smartwatch.Not only smartphone notifications and measurements of activity can be measured, as well as measurement of recent important blood oxygen levels.You can monitor sleep and get advice for a good sleep.I usually use Apple Watch (Series 6), but I can do most of what I can do with Apple Watch.

　The advantage is that the smart band is thin and light, and you do not care about it.Oppo Band Style is about 10.Because it is 3G (only for the main body), there is not much discomfort even if you sleep while wearing it.

　The display is 1.1 inch organic EL.The resolution is 126 x 294 dots, and up to 50 characters can be displayed.The displayed characters are inevitably small and somewhat difficult to read.However, for example, if you receive a message, if you know that you have received it, you can read it on the smartphone screen, even if you do not read it on the smart band screen.1.The 1 -inch screen is small for "reading", but there is no hindrance to "seeing" glimpse, and I do not feel inconvenient.

　The color variations are black and vanilla, and I use black.Two types of straps, style type and sports type, are included, and the body is clicked on the strap frame and fixed.It can be fixed rather strongly and there is no anxiety to come off when installed, but it is necessary to put a little effort to attach and detach.

　For charging, the bundled USB charger is used.The body is clicked there, but it is necessary to put a little effort and put it on.In addition, the style type strap can be charged with it on, but when removing it from the charger, the body may come off from the strap too much.On the other hand, it was difficult to fit the charger if the sports type strap was attached, and it was somewhat inconvenient to remove it every time it was charged.Also, the charger cable is only about 13cm, so it may be inconvenient depending on where to insert it and charge.

　While saying "I liked it," I got a detailed dissatisfaction, but in fact, I was dissatisfied.I am generally satisfied with other usability.

　The battery capacity is 100mAh and can be used for up to 12 days.I didn't measure it exactly, but even if I worked out for about an hour every day, it seemed to have one week.At the moment, the battery level has become a pinch and has never been impatient.If you feel that the batteries are getting less, remove it when you take a bath and charge it, and when you get out of the bath, it is already 100 %.Then, wrap it around your arm again and go to bed.I used it that way.

　There is no physical button on the main unit, and it can be operated only by touching the screen.When tapped from the screen off, the screen lights up (it is possible to automatically turn on when you raise your arm).Tap again to display the activity of the day (the number of steps, the calorie consumption, the workout time, the amount of exercise per day) and the battery level.If you trace to the left, you can return to the original screen.If you trace it down, you can check the notification, and if you trace it up, you will see a menu such as "Workout", "Heart rate", and "blood oxygen level".If you trace to the left, you can switch the dial design.This was the only thing I could do on the second day without getting lost in the operation.

　Oppo Band Style basically plays a role just by wearing it on your arm.A mechanism that automatically records activity and immediately understands the achievement status of the goal.The recorded data is synchronized with the "Hetap Health" app installed on the smartphone and can be confirmed at any time.It has the same feeling of use as a general smart watch.

　Workouts include "outdoor running", "indoor running", "Fat burning running", "walking", "outdoor cycling", "indoor cycling", "lowing machine", "cricket", "cricket", "badminton", "swimming" and "yoga".Can be selected from "Free Training".By the way, the swimming seems to be compatible with the water depth 50m.

　I only tried "outdoor running" and "walking", but I can start measurements with one tap, so I can set goals such as distance and time before start.Pause, resume, and end operation are simple and easy to understand.Since the GPS is not installed, if you want to record the running route, you need to have a paired smartphone.

　The blood oxygen level can be measured by facing the dial, placing the arms on the table, and staying still for about 50 seconds.I measured it several times, but I got a perfect result of 97 to 99 %, so I can trust the performance.Of course, it is not a medical device, so it cannot be used for applications such as diagnosis or treatment, but this is a great advantage because there are still few smart bands that can measure the blood oxygen level.

　The functions used in collaboration with smartphones are rarely used except for notifications and alarms.However, you can search for smartphones from OPPO Band Style (iPhone is not compatible), use as a camera remote control, or control music playback.Impression that the functions required for smart bands are provided without exception.If you are strong and missing, it will be about the payment function.

　Smart bands are mainly healthcare functions and low prices.Smart watches are equipped with a variety of functions, and the price varies depending on the material and performance.I had such an impression, but this year I feel that the border between the two is becoming ambiguous.OPPO Band Style is an impression that it is a compact and affordable smartwatch.Those who emphasize cospa are worth of consideration.
