Sorry, should have explained further before pressing send
I have favourites and interests of which some have 'Adult themes'. No problem on desktop or MacBook but on iPad and iPhone I get a popup telling me that App Store policy does not allow stumbling of adult themes.
WTF!
I can of course Stumble via Safari*, but that kind of defeats the idea of an App for Stumbling if loads of my favourites and interests are not allowed.
Stumbleupon.com. It's also known as a time vortex. You go in, expecting to be finished in ten or fifteen minutes, and three weeks later you come up for air realizing you haven't eaten, used the bathroom, or even moved the whole time. it's a pretty genius website really. I've discovered some great stuff with it.
