Having fun with your wearable yet? Not many Android phone users already have a compatible smartwatch. The swartwatch era has just started but it certainly has the potential to become bigger. There's still so much to improve on the small interface and functionality but one thing we're certain about: the smartwatch is very useful. Instead of bringing your bulky phone if you're going for a quick run or walk around the neighborhood, you can just wear a smartwatch and receive notifications for the important items you need--SMS, calls, and more. And since launcher apps on Android are becoming more popular, launcher apps for Android Wear also make sense.
