Before Buying, Here’s What to Know

Watches came into existence in the 15th Century, and the infamous Wristwatches followed in the 18th Century. As technology advances, digital watches and calculator watches have entered the global market and become a part of our daily lives. The Revolutionary discovery by Steve Mann in 1998 gave us the Smartwatches we use today.

Smartwatches don't have LTE, implying they can't receive calls or texts when not tethered to your smartphone or connected to wi-fi. However, they do have some lofty advantages like it shows who has messaged you or who's calling you without forcing you to look at your phone. The star feature to them is the dedicated fitness tracker, and you're bound to find something that suits you, no matter your smartphone model.

All smartwatches fall between a fitness tracker and something that carries smartphone notifications to your wrist. However, some can work untethered, entirely autonomously from a smartphone, all while your smartphone is miles away. There are also hybrid smartwatches, created by automated watch companies like Fossil, Tag Heuer, and Withings, with traditional watch battery life and sensors to track your movements.

10 Best Smartwatches to Buy in 2021 – Features and Assistances

Well-known as the Best Budget Apple watch, the Apple Watch SE is suitable for most people as it combines most of the Series 6 features.

Apple Watch SE comes in a single aluminium finish. However, it has an optical heart sensor so it can still record the heart rate.

Launched in 2020, the Fitbit Versa 3 is an excellent entry-level smartwatch for iPhone and Android users alike.

Moreover, it has a built-in speaker and microphone, which the previous model lacked. You can use Google Assistant or Amazon Alexa all on your smartwatch's screen. With the reduced price of the Apple Watch Series 3, it's rather tough to suggest the Versa 3 to iPhone users.

10 Best Smartwatches to Buy in 2021 – Features and Assistances

Fitbit Sense succeeds the Ionic as Fitbit's brand-new flagship smartwatch. The Fitbit Sense is very much like Versa 3, with significant differences being health/wellness associated. Unlike the Versa 3, the Sense has three brand-new sensors:

  • EDA - That detect stress
  • Skin temperature sensor - to provide you with early indications for fever or other illness

Overall, the Fitbit Sense is an excellent third-party smartwatch for users who want a lot of wellness data, but it's expensive considering how alike it is to the Versa 3.
