While it could be easier to browse for Android Wear-compatible apps through a link in the Android Wear application, sometimes you’re just browsing through Play Store and looking for new apps to try out. Some apps on the Play Store now show a watch icon to denote that they support Google’s wearable platform. You can see it just below the “What’s New” section and near the age rating after you tap on “Read More.” The icon shown after you tap on “Read More” has the words “Enhanced for Android Wear” attached to it. Hopefully, Google brings this soon to all Android Wear-compatible apps.
