I guess the Titstare app could be considered somehwat misogynist from the angle of promoting the objectification of women... but I think that's pretty weak. Men often look at women they find attractive, that's just a fact and they're playing on that in a vulgar way.
The sad thing is that, aside from the inappropriate venue, they could have curbed all the sexist complaints by simultaneously "offering" a version for women (who, you know, often like to look at attractive men), and of course covering their bases for non-heterosexual users.
The simulated masturbation app isn't mysoginist or sexist (other than the fact that only men have penises, but that's a sexism perpetuated by biology), just highly inappropriate in that setting.
