The latest release of Covenant Eyes for iPhone now support content filtering. From Breaking Free Blog:
The app was released in the winter of 2009 as an accountability tool: monitoring all websites visited through the browser app and sending a regular Internet report to “Accountability Partners” you choose (such as a parent, spouse, or friend).
Now the browser also filters Internet access, blocking websites using age-based settings. (Learn more about the rating system.)
Choose what you want the browser app to do. Do you want it just to monitor Internet activity? Buy just the Accountability service. Do you want it to block websites? Buy just the Filtering service. Or buy both if you want both services.
Buy multiple usernames and choose different services for people who use your devices. Have one username that just filters, another that just monitors, another that does both. It’s entirely up to you.
With the addition of filtering, parents can now provide comprehensive internet protection for their children. Not only will you get the award-winning reporting service provided by Covenant Eyes but you’ll also get a browser that filters unsafe content.
