Our take
Children learn best when they are engaged in their education, and learning through play is one of the best ways to achieve this. There is a huge variety of games, video lessons, and other online edutainment resources for parents to engage their children with, but these often lack the personalised and formal syllabus frameworks received during school hours
Lingokids develops an edutainment mobile application for children aged 2-8, consisting of games, video lessons, and audiobooks for children to learn from independently and with their families. The application is ad-free and certified as kidSAFE, and provides community and analytic tools for parents to keep track of their children's progress and activities
Whilst there are countless edutainment applications competing with the company, Lingokids stands out from the crowd with its approach of curating personalised syllabuses for children as opposed to one-size-fits-all educational exercises. And with numerous awards under its belt, Lingokids has certainly cemented itself as a leading edtech app for kids.
