Beanstack by Zoobean, Inc. provides free personalized recommendations of children’s books and apps. Personalizations are matched to your child's interests and age group. Beanstack is part of the Zoobean company. Zoobean is a personalized children's book club and was started by parents of two who got their funding from the popular show "Shark Tank". They decided to create Beanstack after getting feedback from families who love having recommended books and apps selected for them, but preferred to get them for free, from the library.
