Earlier we posted a method to root (jailbreak) your Samsung Gear 2 / Gear Neo by Skin1980, and one of the great features is that you can install apps onto your Gear 2 Smartwatch from non Samsung Smartphones !!!!

Mod your APK to work with TizenMod 3.0 (Root ROM/ Firmware)
Below is a video that can help some of the above steps:
Here is the Modded version of the Watch Styler App for you to Download
You can also make a donation to the developer, as this stuff takes time and dedication to do.
UPDATE: You can also request for modded APK's on this thread at XDA developers.
