Recommended plugins for "Rate App" functionality in Unity 5?

Like the title says - I’m trying to implement a “rate app please” popup in my iOS apps. I’m guessing the easiest way to do this is by using a plugin from the asset store. I’ve had a look but there don’t seem to be any that specifically state they are safe for unity 5.

Anyone have experience and would recommend?

Thanks everyone.

IOS native plugin. Unity Asset Store - The Best Assets for Game Making

Using it myself.

Using it is also quite easy and usage is well documented.

Provides many more other native functions as well. Worth purchasing!
