Many folks will be carrying an Android Wear smartwatch in the near future. It is only natural to use such a device to track phones and tablets. That’s what Wear Aware aims to offer. It serves as a wireless leash between your Android Wear watch and your phone. If you leave your phone behind, your watch will buzz to alert you. It can also help you locate your phone:
Just say “OK Google, Start Phone Finder”, and your phone will start trying to make you aware of it’s whereabouts by playing an alarm signal. No more running around at home trying to find your phone in silence, or calling it from another phone to find it.
You just have to bring your compatible Android watch and phone, and you are set. This is a free application.
