The study has been conducted to examine the growth of the EdTech companies involved in providing education to children during lockdown and evaluate the transition that took place from offline to online education mode during COVID-19. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach was applied for systematic and structured analysis. Furthermore, the study analysed the impact of digital education on students. The results revealed that the various EdTech companies such as BYJUs and UNACADEMY etc. flourished during the pandemic. However, students' engagement and participation were found to be a serious concern in conducting studies in a digital mode. Furthermore, the teachers in many places were not found comfortable using online education apps. Digital literacy training programs can be organised to counter this issue.
