Dropping the phone: Some models of smartwatches in the Samsung and Apple line-ups feature a mobile network chip, allowing you to plug in a micro SIM card to make and receive calls, texts and emails and access the internet without being paired to your phone. It sounds great, but remember that the smartwatch has a very small battery, so relying on it for communications will drain the power quickly.
The touchscreen, button, and dial (what Apple calls the “crown”) help you zoom in and out and move between apps fairly effortlessly. With this easy navigation it’s easy to forget we’re typing on a screen slightly smaller than an Oreo. In particular, we loved Apple’s app homepage, which displays all of the apps as icons in a honeycomb-like display. You can use the touchscreen to move around, and the dial to zoom in or pan out, to precisely tap on the one you want.
Smartwatches, like smart phones, can also run apps, via your smart phone or right on the watch. These include health and fitness apps (thus the comparison with activity trackers), apps that control functions such as music and the camera on your phone, navigation apps, and more. Because most smartwatches have open software platforms (at least so far), developers are coming up with new and innovative apps that can increase the functionality of the devices.
A smart watch is nice to have and it can be a neat buffer when deciding if you want to answer an incoming call or let it go to voicemail. Smart watches with apps for fitness and travel are also a lot more convenient in some cases than having your smartphone. However, if you prefer to use your iPhone for these and other activities, you probably won’t get much more out of a smart watch.
