Using it to take calls and voice chat isn't that reliable and Hey Meta is very unreliable.
This version feels like smart glasses beta 1 but I do highly recommend then from my two weeks of frequent usage (bought them day they just came out) for taking pics n short videos!!
Overall good job Meta/Zuckerbrrg ..excited for the next version where all features work reliably and a few more smart features are added /work well like binoculars mode :)
To answer your question and based on my usage I don't think they could run any developer apps or programs and or reliably so. So I say closed for outside development until the next and fourth version.
