SmartWatch: Amazfit GTR 2 New Version

As a result, Amazfit chose to refurbish and resell the older but still popular model. The novelty features a round 1.39-inch AMOLED touch screen with a 454 x 454-pixel resolution.

It allows you to view dials straight from the manufacturer as well as notifications from your smartphone. The watch's body is somewhat rounded on the sides, and it is water-resistant to 5 ATM.

The watch also includes 3 GB of internal storage. You may record athletic activities while listening to music without having to carry a smartphone in your pocket.

The watch's software has more than 90 sporting modes. They can monitor your heart rate, blood oxygenation, steps and kilometers traveled, sleep, and stress levels.

On the plus side, they contain a microphone and a speaker, so they may be used to make phone calls when connected to a smartphone. The manufacturer promises that a single charge will last 11 days of normal use.

They should provide endurance for up to 38 days in a mild mode. Connectivity is handled by Bluetooth 5.0 LE and Wi-Fi (2.4GHz).

GPS and GLONASS satellite systems are also supported. These will primarily be utilized for route records during sporting events. You're unlikely to come across the pre-installed watch navigation.

The watch availability and pricing have yet to be disclosed.

Research: All smartwatches measure calories burned inaccurately

The study was published in January of this year, and the researchers attempted to assess the utility of smart wrist devices for monitoring energy consumption and heart rate.

30 healthy male and female participants were tested on the 6th generation Apple Watch, Polar Vantage V, and Fitbit Sense. They focused on strength training, cycling, jogging, walking, and even sitting.

The Polar H10 and MetaMax 3B chest straps were employed as reference devices by the researchers. The research team at Stronger by Science presented the findings in a simple table that evaluates the accuracy, variability, and reliability of each instrument. However, in terms of calories, the results are not very flattering.

However, the test revealed some positive results. In step measurement, all devices performed admirably and produced relatively precise results. In all activities, the Apple Watch 6 assessed the heart rate more reliably than the other two devices. The results of Polar and Fitbit devices changed depending on the activity undertaken.

Although research on a small number of devices and persons has been conducted, it appears that commercially available smartwatches and fitness bracelets do not provide trustworthy estimations of your daily energy expenditure. On the contrary, heart rate monitoring and step counting are extremely accurate.

Smart wearable technologies can, however, have a significant impact on a person's active life. People who use such gadgets tend to increase their overall activity and amount of steps, regardless of measuring accuracy. And anything that gets people moving is beneficial.
