Qustodio is a cross-platform tool that can monitor Windows, Apple products, Android, and a few other common household devices with internet access.
Qustodio’s multifunctional approach makes it easy to protect and monitor every device in your home from the same platform. The service includes all the most important features, like website filtering and device and internet time limits, and gives you a detailed 30-day activity log.
The free plan covers only a single device, which might have been passable in the 1990s, but nowadays you have smartphones, laptops, and tablets, all of which can access the internet. So we definitely recommend Qustodio’s paid plans. It has three plans that scale in price based on your monitoring plans, with the cheapest starting at $54.95/year with coverage over five devices.
