The ease of use is great for any type of AR app development including games or other applications that require an AR experience. There are many different types of SDKs from which to choose so it's easy to find what you need. It can be difficult to get started with some of the more complex features but once they're set up everything works well. I have not found anything that really needs improvement at this time. We've been able to build several apps using Augwir and there has been no issues as far as getting them working correctly. Our first project was a game where we were trying to teach kids about how to safely operate machinery by having them play a game.
