By measuring the levels of hormones in a woman’s body one will know with almost 100% certainty where in the monthly cycle she is. Salvia (spit) is the perfect place to measure hormones and takes five seconds.

With this knowledge at hand on her mobile phone she will know if she is fertile or not on any particular day. A woman can only conceive six days a month. Body knowledge empowers woman to make clever choices for themselves about family planning.
