I've been pleased to see swim-tracking trickle down into more affordable devices over the past few years. Fitbit's Flex 2 remains its most affordable device with swim-tracking features, priced at $60. But the $150 Charge 3, with its big display and smattering of smartwatch capabilities, is for a different audience than those who would gravitate to the tiny, quasi-cylindrical Flex 2. Even if you don't swim often, water-resistance up to 50 meters means users don't have to worry about showering with the Charge 3 or dropping it in the pool by accident.
The Passport is versatile in that it works with Android and iOS mobile devices. And it features the ability to make phone calls with its built-in microphone and speaker. You can use voice commands (the Passport leverages your phone's voice recognition system; such as Apple's Siri for iOS devices or Google Now for Android) to control the mobile device from the watch. And because of the analog watch face, you can easily see the time in bright sunlight.
The LG G Watch was the first one we tried that uses Google’s Android Wear OS (the Moto 360 and Samsung Gear Live do as well). It includes Google Now, the company's Siri-like "intelligent personal assistant." Say “OK Google,” and you can do Google searches, compose texts, and make requests of your watch (“Show me my steps” or “Set an alarm”). Google Now also offers up a stream of "cards" on the watch's face, with information it determines is relevant to you. If, for example, the card tells you how many minutes it would take you to get home from your current location, you can click on the card and get specific traffic and navigation information.
Apple Watch Series 3: If you are an iPhone user and generally exist in Apple’s ecosystem, it makes sense to get an Apple Watch. The design quality is exceptional and the Watch makes a nice pairing with your iPhone as materials and design elements are common to both. Apple’s Health app covers most of the bases when it comes to tracking your essential fitness and activity indicators - nutrition, sleep, physical exercise, but Apple has gone further with HealthKit, which allows health and fitness apps downloaded from the App Store to share data with each other. Apple has committed to Watch, and its attention to practical and eye-pleasing design as well as useful tracking features is commendable. ($529)
For deeper integration with your Android phone, you can give Google's Wear OS platform a try with Fossil's $275 Q Control touchscreen smartwatch. It lacks GPS and support for NFC payments, which is why the Gear Sport is a better fitness-focused smartwatch for Android users, but Fossil's Google Assistant integration and stylish design make it a solid contender. However, smartwatches with Qualcomm's new Snapdragon Wear 3100 processor start shipping in October, so you may want to hold off until we put them to the test.
