It makes it easy for teachers send messages directly from one student's profile page without having any problems related to privacy or security of students' personal data; I like how they have managed this app so well! There are no features which irritate me but if there were more options then maybe we could use them in future too. The interface looks simple as compared to other apps available out here right now because it has made its way into school education system quite easily when used wisely (which means using childdiary mostly). Teachers love sharing their updates about each class member via messaging feature through kid diary application at ease while sitting idle over coffee break/ tea time etc.,.
