Hi Comol, I can recommend Plano App is a science-based parental control app that empowers responsible device use and helps manage your child's vision and eye health! This app is designed to reduce the risk factors associated with myopia (short-sightedness) and manage your child's device use, all at the same time. The Plano app was created with support from the Singapore Eye Research Institute (SERI) and the Singapore National Eye Center (SNEC). Plano's features help parents to set the screen time limit, manage and block inappropriate apps, control, track and monitor child's phone, and many more.
