Paid APKs on Gear
I've noticed people cannot port paid APKs (or haven't) to the Gear due to licensing, no internet, etc.
If you have purchased the app on your account, I recommend using 'APK Downloader', a Chrome extension that uses your Google Account to download the APK file directly from the play store through the browser. Then use Wondershare to install the paid APK to you Gear
Alternatively, you can download the paid APK to your phone and navigate to "/data/app" and copy it to your computer (using Wondershare) then porting it to the Gear again.
Obviously you need root, and these are the methods I've been using.

I can confirm this works on apps such as Root Explorer, Nova, Apex, AlarmDroid, Emulators, UCCW, Widgets, and I'd imagine most, if not all paid APKs.
