Qustodio

Once you've purchased your subscription, you install a local client on the device you want to track and assign it to a child's profile. Qustodio works on Windows, macOS, Android, iOS, Kindle, and Nook devices.

The activity summary breaks down your child's activity in a pie chart. You can click on any of these slices for more details.

Qustodio's content filtering is browser-independent, so kids can't just install a separate browser to get around restrictions. You can block categories of websites for broad control add specific domains.

Each application that your child launches shows up in the online console. You can block any of these apps from this screen or set a time usage limit.

You can monitor and control mostly everything that you can from the web dashboard on mobile. It offers apps for both Android and iOS devices, though the iOS offering is limited.
