It is well suited in scenarios like you wants to track objects and surface in the plane. Image recognization at multiple targets is one of the very good functionalities of EasyAR. And if you want to render 3d objects in your mobile application then it's well suited. It is free too so you can create applications at minimal costs.
Spark AR Studio is used to create AR experiences for the Brand Partners. The AR experience is created so interactive that the user is attracted to use the filter many times
EasyAr is free and there is no watermark on the output of it. It's easy to use and some features like multiple targeting in images and object and surface tracking help you to achieve what you want.
I have used Spark AR Studio for the first time to create AR experiences and it deeply satisfies me. I have never used other software similar to this. It is most simple and creative software which I have ever found till now.
