A few young Israeli entrepreneurs saw an opening that they are filling with a new product called Remini, which is used a great deal in Israel, to some extent across this country, including by Barnert Temple in Franklin Lakes, Gan Aviv in Fair Lawn and Bergenfield, and by schools as far afield in every way as one in Dubai. Remini allows teachers and other educators to upload photos and messages to parents. Messages can go to the whole school, an entire class, a specific group of parents, or just one set of them. Parents can save photos and messages on the child’s own timeline — it’s backed up in the cloud — so a child’s entire early childhood can be documented and parents — and grandparents, should the parents decide to invite them — can gain access to it easily. Parents cannot upload content to the main part of the app, although they can to the timeline, but if the teacher or administrator agrees, they can exchange private messages.
