Review on AR SDK by Jason Graham

Easy integration, works great in Unity game engine. Support of multiple devices (iOS/Android) which makes it good choice if you want your product available worldwide. It takes some time get used but once we figured out how things work its very easy! We are using this sdk only because unity supports it natively so there's no need to use other SDKs like Vuforia etc. If u have already integrated Unity then go ahead otherwise I would suggest doing research first before deciding what framework will fit best in ur case. Tracking feature has been one of our major pain point when working on VR projects especially since most customers don't buy headsets. This solved almost 90% of issues related to trackable objects.
