Take this idea and run: the find-your-double app. You take a selfie, the app analyses it and tells you where your identical twin, I mean, your identical twin from-another-mother is to be found.
I’d love to have something like this out there, but won’t be able to start a new thing just now. (Insert sad smiley here.)
Another brilliant idea that I had before has just been made by PornHub: the BangFit is a fitness tracker service that tracks a special kind of fitness. Though this one is done by PornHub, so I guess it will eventually measure the mhm, exercise of men’s underarm?
There, a pivot idea for takers: WankFit.
