Cross platform AR development alternatives

Hi
Need some ‘refresher’ tutorials on cross AR platform development as I haven’t done any AR development in over a year and the landscape has changed significantly in that time.

Is Vuforia the best choice for marker based tracking if I need to target BOTH android and iOS?

Any feedback appreciated!

Until ARFoundaton support marker based tracking ( which should be coming in the next update ), then Vuforia is currently the best choice if you want to target both systems.

Thanks!
