The best thing is it is easy to integrate and provide ecurate AR features. I tried it with agora sdk and worked well.

Easy AR, what I liked the most is the ease of making 3D games and augmented reality with Unity and other development tools, its easy integration is super useful.

EasyAR is quite easy to use and set up. There are some included samples that should get most people using it in a few minutes. I have spoken to support twice, and have gotten an answer to my concerns (usually two business days later).
