my goal is, to be able to see what impact different algorithms have on the performance. I couldn't find an iOS app, that enables this feature for other apps and it is not a feature of vuforia view. Of course, we can check the fps in the preview via console, but I would like to check it on the end device.
A similar question - "Display framerate in app": https://developer.vuforia.com/forum/unity-extension-technical-discussion/display-framerate-app

Thanks for you reply, but to be honest, I have no Idea how a link to the Vuforia Engine forum could help in this case. I cannot use java an I have no access to unity's tools.
One way I can imagine is, to use the tml3Renderer & three.js, but I don't konw how.
