If your kids have smartphones, you know that it’s a full-time job trying to keep track and control their usage. According to recently released data from the National Institute of Statistics (INE), 94% of 15-year-olds have a mobile phone, 86% of minors are on the internet without any content filtering systems, and 28% to 38% of minors access unsafe or harmful content with those rates escalating as they get older.

Parental-control apps have made monitoring and protecting children much easier these days, giving you the ability to track locations, block objectionable or dangerous websites, restrict access to social media or games, and monitor who kids are communicating with. In the long run, these apps can also help children to develop good habits for how they use smartphones as they grow up.

We know it can be confusing to know what works best for you and your family, so we compiled a list of highly-rated apps to give you an idea of the resources and options available for monitoring children’s smartphone usage. What you choose will depend on factors such as your child’s age and what they use their phone for to decide which is best for you.

Before you decide to download or start using a new app, remember that there are often parental controls built into most phones these days that you might already have but not be aware of. For example, Google’s Family Link is very handy, Amazon’s parental controls are excellent, and Apple offers some parental controls too.
