Apple Watch Series 7, Fitbit Sense and Samsung Galaxy Watch 4 Review

#1  Apple Watch Series 7

The Apple Watch Series 7 is Apple's new flagship smartwatch. While the Series 7 is only an incremental upgrade over last year's Series 6, that doesn't stop it from being one of the best smartwatches you can buy - if you have an iPhone, that is.  Along with all of the additions and improvements from 2020's Apple Watch –  namely an always-on altimeter and blood oxygen monitoring – the Series 7 also incorporates fast charging (that's 33% quicker than before) and a new display that's 20% larger, while bezels around 40% thinner, giving the Watch a more cutting-edge look while retaining compatibility with existing Apple Watch straps. In addiion, the seventh-generation Apple gets some exclusive watch faces and a full QWERTY keyboard, too.


Running watchOS 8 out the box also means newfound support for workout activities like pilates and helpful new safety features, like fall detection whilst cycling.In a word,the Apple Watch Series 7boasts a fluid performance, trouble-free setup, and smooth haptics. With its clean software and seamless ecosystem integration, you can enjoy an almost flawless experience. You can handle your phone notifications, including calls, texts, and replies to messages, with ease. The health monitoring features work incredibly well. Whether you want a smartwatch for working out, answering calls from your wrist, or using the best Apple Watch apps, this is the best smartwatch for you.

#2  Fitbit Sense

Fitbit Sense is Fitbit's most advanced smartwatch to date. All of its heath features work impressively, from the ECG and EDA sensor to skin temperature and SpO2 sensor. It’s a great smartwatch for fitness, too, thanks to its GPS and heart rate monitor. In fact, its GPS is so responsive that the watch is among the best running watches you can buy today. In terms of other smartwatch features, it’s not as robust as the Apple Watch 6 or Samsung Galaxy Watch Active 3. However, it covers all the basics incredibly. You can answer calls via the watch when your phone is nearby, and you can listen to music through third-party apps like Spotify and Deezer. The battery life is epic, lasting up to 6 days.


What‘s the pity is that some of its tools are hidden behind the Fitbit Premium paywall. If you’re happy to subscribe and want the best “health watch,” then the Fitbit Sense is well-worth considering. It can measure stress levels, monitor heart rate, track your sleep, sense skin temperature, and even measure electrodermal activity, making it the best tracker of health money can buy today. Besides health features, it’s also able to take hands-free calls. In addition, you can also Google Assistant and Amazon Alexa voice assistant from this watch.

#3  Samsung Galaxy Watch 4

The Galaxy Watch 4 is the first smartwatch to run the new Google Wear platform, co-designed by Samsung and Google. The Samsung Galaxy Watch 4 is a huge reset for the Samsung brand, and hits reset on four generations of devices by moving to Wear OS and merging Galaxy Watch and Active brands. And it's the undisputed best watch for Android users, with Samsung returning to run the new revamped Wear 3.0 with a superb integration.As other smartwatches, the Galaxy Watch 4 offer plenty of features which include everything from activity tracking to notifying you of the latest messages you’ve received. You also get a solid heart rate sensor on both as well as access to the new body composition metrics.


Add to that great performance, what I found to be a comfortable fit, a lightweight build, and interesting new body composition measurement tools, and this makes for a top smartwatch, especially for those interested in tracking their health and fitness.There are some drawbacks to keep in mind, though. The charging is slow, there’s no Google Assistant support, and the GPS performance isn’t the best. Still, the pros outweigh the cons, and the watch most definitely won’t let you down.If you own an samsung phone, the Samsung Galaxy Watch 4 is the best smartwatch money can buy right now.

The Apple Watch Series 7, Samsung Galaxy Watch 4 and Fitbit Sense are an excellent collection of premium smartwatches.Which one is best for you may depends on the phone you use and what you want from the watch. First, The Apple Watch is the top choice for iPhone users, while the Galaxy Watch 4 and Fitbit Sense are the top choice for Android users.

With faster performance, brighter display, and various new features, the Apple Watch Series 7 has everything to stay the king of smartwatches.

The Fitbit Sense is a robust health watch, so I recommend it to those who want as much health data as they can muster. Its heart rate monitor and sleep tracker are better than its rivals. Overall, it can put you in tune with your body and health. However, if you want a smartwatch that will let you control all your smart home devices and check your bank balances, Fitbit Sense is not for you. 

A fantastic screen and a top array of health features make the Galaxy Watch 4 a great smartwatch. And the move to Wear OS 3.0 means the selection of apps on offer makes it the best Galaxy Watch yet.
