If you like traditional analog watches and want just a few smart features, the Cookoo 2 might be more appealing than its more full-featured rectangular competitors. Behind its hands is a monochrome display that delivers basic notifications: incoming calls (with Caller ID), missed calls, texts, e-mail, social media alerts (for WhatsApp, Line, QQ, WeChat, Skype, Facebook, Twitter), and calendar alerts. Just bear in mind that it's a very basic smartwatch, with little configurability.
Fitbit OS 2.0 brings a new-look UI that offers more insights into your daily data and quick reply support for messages for Android phone users (iOS support coming at a later date). You can still download apps and a whole lot of watch faces, pay from your wrist using Fitbit Pay and tap into Fitbit Coach, while new women's health tracking has also been introduced for the first time, which is also available for the Ionic, too.
Our top pick for most people is the Apple Watch Series 4 with GPS (starting at $399), which has a huge display, ultra-fast processor, Raise to Speak Siri, fall detection and a built-in electrical heart rate sensor for taking on-the-go electrocardiograms. It also runs watchOS 5, which makes the watch even more useful with automatic workout-tracking, offline podcast playback and a Walkie-Talkie voice chat feature.
