"GALAXY WATCH4" Self -purchase experience, smart watch that can measure body composition data!

I purchased Galaxy Watch4 for measuring body composition data

One is because Galaxy Watch4 has a function that can easily measure body composition data on the wrist.At the moment, Apple Watch has no functions that can be done by hardware alone.

I previously reported a smart body weight "BODY CARDIO" that can measure the body composition data of WITHINGS.

If you can regularly check not only weight but also body composition data that is an indicator of overweight and muscle weakness, you will be able to make the results of moving your body in sports, such as jogging, will be clearly visible, improving and maintaining your physical strength.It was connected to.

I can't carry a smart weight, but I hope that a smartwatch will be more convenient because you can check your body comparison data immediately after moving your body or on a travel destination.

Another reason is that I wanted to try Wearos Powered by Samsung.I also use some smart watches in Wearos, but I want to know the evolution of the new wearable OS (WearOS Powered by Samsung) developed by Google and Samsung, or that becomes inconvenient.I thought.

Unfortunately, I found one of the inconvenience of the latter.If you use a smart watch equipped with the conventional Google genuine Wearos, you may not be able to use some functions compared to the Android smartphone, which may be inconvenient.However, Galaxy Watch4 cannot be used by pairing on the iPhone in the first place.

Android 6 to use Galaxy Watch4.You will need an Android device equipped with 0 or later.As expected, smartphones don't have to be Samsung's Galaxy series, but I wanted the iPhone user to open the door.This time, I installed the app on Google Pixel 5a (5g) and paired Galaxy Watch4.

Light mounting feeling.Waterproof and dustproof support

I purchased a Bluetooth/Wi-Fi model with a case size of 44 mm.I had a thin wrist, so a 40mm model was fine, but I chose 44 mm because I wanted green.

Galaxy Watch4 weighs about 30 excluding straps..3G.The head is light and slim, so I think it's comfortable to wear.The body is 5 aThesis waterproof specifications in addition to dustproof and waterproofing of IP68, so you can wear it and swim in the pool.

The attached silicon strap is useful because it is resistant to wet and dirt, but the band is easy to put on and take off by removing the pin.I want you to add a change of dressing band.

There are many functions that overlap between Galaxy Watch and Apple Watch, such as measuring heartbeats and recording activities.But that doesn't mean we can stop the data records of activities and healthcare that have been recorded for many years on Apple Watch.

I don't care much about wearing a wristwatch on the left and right, but it's hard to spend every day on both wrists, so I'm going to consider using a daily and weekly shift.I am.

According to an overseas research company, as of the first quarter of 2021, Apple Watch has gained more than one -third of the total shipments in the world's smartwatch market.

In the future, manufacturers that plan and develop a portable type fitness device that have functions that cannot be realized in the Apple Watch will also look at the development of smart devices as "accessories" such as rings, pendants, and earrings other than watches.It may be good.Or maybe a device such as a slender bracelet that can be worn on your wrist with Apple Watch?

Measure the long -awaited body composition data.Manage with a smartphone

After completing the initial setting of Galaxy Watch4, I first measured the body composition data.The Galaxy Watch4 is also the same as the Body Cardio of Withings, and the flow of current when a weak current is flowing to the human body by using the "Biole Electrical Impedance Analysis" by the same "BIOELECTRICTRICAL Impedance Analysis).We adopt a technology to measure and derive body composition.It is safe because it does not come to the body even if you say that it flows electricity.

Measure the body composition data in close contact with the sensor on the back of the main unit with the finger on the two buttons on the side of the case.The measurement is completed in about 15 to 20 seconds.

Galaxy Watch4, a wrist device, does not lose weight, unlike the smart weight meter of withings.Therefore, before starting the measurement, it is necessary to weight and input separately.

The data that can be measured with Galaxy Watch4 is skeletal muscle (muscle mass), body fat and body fat percentage, BMI (body mass index), BMR (basal metabolism), and body water content.Since physical composition data does not support automatic measurement, the data that users voluntarily record the data is accumulated in the S Health application.

If you link to your smartphone and the app, you can manage the data measured by Galaxy Watch4 together, use a smartphone with a graph, or see the numerical change from the previous measurement with comments.

Data that can be measured with Galaxy Watch4 and keeps records in the S Health app includes other heart rate, blood oxygen level (SPO2), and stress measurement.

The sleep tracking function also has a sub -menu that evaluates the depth of sleep (= sleep quality), and is detected by detecting a snoring time with a smartphone built -in microphone.

The healthcare function equipped with Galaxy Watch4 and the fitness functions that are useful for sports scenes will be used for about a month and will be described in detail as a long lunchech report.

New Wearos with well -working with hardware

The Wearos Powered by Samsung, which I was worried about, has a good coordination with the hardware, has a very sensitive and comfortable touch operation response and app operation.I think it's an interface that can be used comfortably compared to smart watches equipped with Wear OS that I have tried so far.

Body composition, heart rate, and stress measurement apps can be quickly called from "tiles" displayed when swiping the home screen.

Swipe the home screen from below to display the icon of the installed app.It is attractive that Google Maps and Play stores are pre -installed, but on the other hand, there are some pre -installed apps that are not required if you do not use the Galaxy series device.Press and hold the icon and select deletion to organize the list.

When you open the Google Play Store, you can search for apps for each theme, and it also supports free word search.Classic pre -pre -pre, such as Google Fit, Spotify, IFTTT, YouTube Music, SHAZAM, and meditation app Calm, are likely to be found in the same way as before.You can download the app directly from Galaxy Watch4 without going through a smartphone, but you need a smartphone to settle the billing content.

The battery is good.I want a stylish dial

The battery capacity built by a 44mm model is 361mAh.The nominal specifications are about 40 hours of continuous drive, but as a guide, it can be used for about a day and a half (from full charge).

If you charge somewhere after dinner time, you will be able to use sleep tracking without worrying about running out of battery.Use a Galaxy Watch4 dedicated charger for the charge.

Galaxy Watch4 is generally good in first impressions, but if you place an order, you will not find a dial that suits your taste.Because it is a watch with an elegant design, I would like you to collaborate and provide a galaxy genuine dial with a more luxurious and calm design with designers.

Galaxy Watch4's Fitness Healthcare -related deep -exclusive long lunch check will be delivered again in this series.
