Most of the schools uses a school diary for communication between parent and teacher. But using this method has many limitations. In this paper we have researched about the various factors as to why this type of communication is not effective and why we should switch to digital communication. We have also reviewed our android mobile application ‘Guide N Grow’, which is used for digital communication between parents, school and teachers. By using this system, any school can make the communication between parent and teacher more effective. Parents can take care of their child’s academics and can also get the regular updates from the school. Due to the use of this system they can take their child’s performance at a good level. By considering all these factors one can make a school to a smart school.
