The moto 360 generation one android wear smart watch was released in September 2014.
To get access to all of the features of Android wear and a large range of watch faces it is best suited to use with Android devices. However it can also be paired to an iPhone but its functionality is somewhat limited to receiving notifications and controlling your music apps.
The JOBY Grip tight auto vent clip is ideal for mounting your iphone 6S Plus or extra large android phone inside your car. I have the XL version here which retails at around $36 US. And this is going to be suited to larger phones with 5.5 inch screens such as the iPhone 6s plus.
