I found this on page 6 of YAPPADAPPADOO whitepaper and it is really interesting to know that YAPPADAPPADOO team promotes sharing of apps which is a good thing for people who have already purchased the applications. It will somehow create new friends and encourage everyone to be generous.
Users will love yappadappadoo, because they can access a universe of Progressive Web Applications. They can try out applications spontaneously and quickly. With Blockchain technology they can buy, use, and even transfer applications to other users.
