Smartwatch features and how to use them. Check compatibility with smartphones
A smartwatch is a wristwatch-type wearable terminal that can be used in conjunction with a smartphone.

Apple’s “Apple Watch Series” can only work with the company’s “iPhone”. And although there are products available for both the iPhone and his Android smartphone, different smartwatch and smartphone manufacturers may differ in what the app can do.
You can check notifications such as incoming calls to your smartphone, SNS apps and news apps on your smartwatch. Some models can reply to fixed phrases or make calls as they are. You can check various notifications on your smartwatch, so you won’t miss important messages or information even when your smartphone is in your bag or you are working on your computer.

As for heart rate, if you check the number during exercise, you can understand how much stress your body is putting on.
You can also measure your sleep level, such as when you fall asleep and the depth of your sleep, and your stress level, which shows how tense you are. The accuracy of these functions is improving year by year, and the reliability is increasing.

Many of them allow you to set a target value for your workout, which can be used for dieting.

Furthermore, if you use the coaching function, it is also effective to maintain motivation for exercise and improve efficiency. Some outdoor models are equipped with GPS, compass, altimeter, barometer, etc.
If you have an electronic money payment app such as “Mobile Suica” installed on your smartwatch, you can make payments at convenience stores and other places by simply holding your smartwatch over the ticket gate at a station, just like you would with a Suica card. Recently, the number of smartwatches that support credit card payments is increasing.
