Best Android smartwatch

There are several models we would recommend. Their performance is stunning, and your choice among two options is often a matter of style and specific features.

Samsung Galaxy Watch 3

This smartwatch can check blood pressure and take an ECG by pressing the push-button on the dial for as long as 30 seconds. Like the Apple Watch, it can measure the oxygen levels in your blood, allowing you to check your current sports activities' progress.

It has over 120 home-workout programs, as well as one for sleep advice and tracking. Regarding tracking, Samsung has partnered with the National Sleep Foundation to provide better guidance on adopting correct behavior.

Please, let me highlight the Smart Reply feature, which analyzes messages and photos you receive and suggests answers related to macro-categories like food, celebrations, and more.


  •   Dimensions: 46,2 x 45,0 x 11,1 mm and a weight of 53,8 g

  •   Display: 1,4 "(34.5mm), with Super AMOLED technology and 360 x 360 resolution with 16M color depth

  •   Battery: 340mAh capacity, lasting more than 56 hours under intensive use and up to 151 hours under standard use

  •   Sensors: Accelerometer, Barometer, Gyroscope, Brightness Sensor, Optical Heart Rate Sensor

This smartwatch perfectly blends functionality with aesthetics. The appearance is distinctly different from its competitors, looking more like a real watch. Its design is a killer and adopts a rotating bezel to shift between apps quickly.

It is available in two sizes, three colors: Mystic Black, Mystic Silver, and Mystic Bronze.

Here you'll find the official page showing the Samsung Galaxy Watch 3 in detail.

Samsung Galaxy Watch Active 2

If you are a sports lover, here is your smartwatch. It can monitor seven sports activities at the same time, without you needing to do anything: wear it, start moving, and it'll start tracking. If you need to monitor additional activities, you can enter the manual mode and do whatever you like.

This smartwatch for Android offers a function called Running Coach, which gives you real-time tips to achieve your previously set running goals. However, sports activities are only one of many kinds of monitoring processes you can use. For example, you can control your state of stress and manage it thanks to guided breathing exercises.

However, the truth is that Samsung's Tizen platform (this Samsung runs on this specific platform) offers a limited number of apps compared to Apple's.


  • Dimensions: 44,0 x 44,0 x 10,9 mm, weight 30 g

  • Display: 1.4 "(34.5mm) size, Super AMOLED technology, 360x360 resolution, 16M color depth

  • Sensors: Accelerometer, Barometer, Gyroscope, HR Sensor, Brightness Sensor

Among the other features are:

  • Military-grade resistance under the most adverse conditions: waterproof up to 5 ATM and IP68 dust proofness

  • Excellent compatibility with smartphones from other brands (albeit with exceptions depending on the country)

  • Available in different strap colors

It is a smartwatch that also takes style into account, as well as performance. An additional feature helps you match dial color and outfit: take a picture of what you're wearing, and it'll let you select a color-matching dial.
