Legit, the only women who will be okay with this are those who are not of sound mind or too young and naive to see what it truly means. This app is definitely dangerous.
As for why? Lets be real-- it was made by dudes who think of sex as a contract. They probably have money and power and can actually get some ppl to sogn this. The perfect example is Aziz Ansari incident. Being an independant, self actualized and confident women is still going against the grain in society. Most women will try to be polite to get out of something, including aggreeing to oral sex in a contract. Cuz, its somehow not as bad...
