Download Android Wear apps right from your wrist
Android Wear smartwatches aren’t yet completely independent of your phone, but they just took one giant step in that direction. Google is releasing a third developer preview of Android Wear 2.0 that offers Google Play Store access on your watch, complete with support for paid downloads, beta tests and multiple accounts. Browsing is limited to recommend apps and keyword searches, but you can choose to install apps only on the watch — important when some Android Wear 2.0 apps won’t be available on phones in the first place.
You’ll have to be comfortable with running unfinished software if you’re going to install this on your own watch, of course. Otherwise, you’ll have to be patient. Google isn’t expecting 2.0 to reach wearables until early 2017, so the preview program will be the only way you can try the new Android Wear experience this year.
