Gavra, no thanks, I’ll stick to the yeraim. There are also those who aren’t nispoel from the issur k’siva (such as the developer of the app, if this is for real), but zilzul Shabbos is very real.
If it were only zilzul, I would say so (and insist that it’s still very much assur), but it happens to not be.
Re: Tzitz Eliezer, see the part where he quotes the Sh’eilas Yaakov, especially the end of the S”Y’s teshuvah.
