While Android Wear and its complementary devices have only been in the hands of the public for a short time, there are unfortunately still some issues that need to be worked out. As of right now, a bug is preventing users from installing paid applications onto their Android Wear devices.
Android Wear apps are actually installed via your Android smartphone. When you download an app on the phone, it checks to see if there is an Android Wear interface as well, automatically installing it on your watch if there is. It seems that paid applications that are purchased on Android phones won’t install the Android Wear counterpart.
While there certainly isn’t a ton of apps currently available for Android Wear, most of the ones that do exist are free, meaning this bug isn’t likely to affect a lot of users. The bug likely stems from the app encryption feature that was released last year in Android 4.1 Jelly Bean.
As of right now, the only workaround is for developers to temporarily release a free version of their applications if they are really determined to get them on Android Wear devices. Google has yet to publicly acknowledge this huge oversight, but seeing as this is a major issue, we should be expecting a fix sooner rather than later.
