We have done 25 AR geocaches in a several different states by numerous COs. Almost all used Metaverse. My wife uses Cachly on he iPhone and I use the Geocaching App on my Android.
It took a bit of work to figure out how to best use the app and how to do stages. Some were location-based and others were not. Overall we enjoyed them but it would need to be easier to use for it to become main stream.
