It's being reported that the smartphone app would need 60% of population to be using it to work.

So that's six sevenths (fuck that maths) of all smartphone owners using it. Yarp.

Lucky for you, sevenths are easy. Simply memorise "142857" and rotate the digits as necessary to achieve the correct fraction. 6/7 is therefore 0.857142... with the 6 digits after the point repeating.

Thanks. If I´m ever single again I´ll use this to pull a tasty math(s) teacher.
