Still, it's possible the prices will be significantly higher by the time you read this.) (As we write, the company says these prices are discounted, with '30% off for a limited time.' A quick visit to the Wayback Machine showed Net Nanny offering the same prices six months ago, though, so it doesn't seem that limited. The second covers up to five desktop or mobile devices for $55, and the third protects up to 20 devices for an annual $90. The first protects a single desktop for $40 a year.

Net Nanny's pricing is a little more complicated than usual, with three plans on offer. That's an issue with all parental control apps, though, and the ability to offer even partial protection on desktops is still a major plus point. Keep in mind that features vary depending on the platform - Windows and Mac laptops don't support location tracking, for instance. Support for Windows, Mac, Android, iOS and Kindle Fire ensures you can run Net Nanny just about anywhere.
