Samsung's Gear S3 is a smartwatch that made it big on the market in an attempt to compete against the Apple Watch series. This larger-than-average watch offers most of the hallmarks one would expect of a trendy smartwatch: near-field communication (NFC), GPS, activity tracking, heart rate monitor, altimeter (altitude meter), water resistance, and, in some models, Long Term Evolution (LTE).
The Gear S3 features two models: the ""Classic"" look or a ""Frontier"" finish, and they both feel great to wear. Its screen is high-end with a large face. On a full charge, the Samsung Gear S3 can operate well over 24 hours before needing to be recharged—this is with normal active use, of course. It runs on Tizen which is a Linux-based operating system created and managed by the Linux Foundation, with fewer apps than Google's Wear OS. The limited number of applications could set the Gear S3 smartwatch back, especially when you compared it to the Huawei Watch 2, the Fitbit Ionic Watch (by Adidas), and the LG Watch Sport.
Many people who follow the smartwatch tech trends ask: Why did Samsung opt to operate on Tizen? Is there any more room for a third smartwatch operating system? What is Samsung trying to achieve that other major smartwatch makers haven't already?
These are some pretty legit questions. However, there are a few major selling points that still make the Gear S3 a good choice for some, despite a shortage of apps. For one, not only is the Gear S3 compatible with all the latest Samsung smartphones but it can pair with most other Android smartphones operating KitKat 4.4 or newer—as long as they have 1.5 GB of RAM available after running everything else.
Another really remarkable feature is that the Gear S3 will soon be compatible with the iPhone 5 and above, being that the device is running iOS 9 software or higher. Whatever smartphone you have now, it most likely is compatible with the Samsung Gear, which means if you chose to purchase the Gear S3, you wouldn't be forced to stick to one smartphone operating system. And this is why Samsung chose to go with Tizen. Plus, given a little time, Tizen will offer an increasing number of Linux-based, open-source applications.
