I’m not judging Artscroll. Hopefully they asked gedolim whether they should make a gemara app. If not, chances are their lot will be the same as all those who transgress the psak of the gedolim, whatever that will end up being after 120.
The entire gemorah is already scanned and OCR’ed (Meaning its in text mode already) and there are only about 6000 (I think) different words in the Gemorah. it would not be too difficult to make an automatic translation of the Gemorah into english that is searchable. Better for ArtScroll to do it properly than someone else with different motives
