It's not simply the fact that digital dangers are lurking everywhere in the mobile age. It's also that the internet never goes to sleep -- or stops demanding our attention. This is particularly challenging for kids armed with smartphones and disappearing-message apps, who may really believe that their next text, tweet or viral video cannot wait until tomorrow.

Parental-control apps for smartphones can also help kids understand the value of limits in a digital world while preventing them from accessing adult content or texting with strangers.

No one parental-control service is perfect, but our testing found that  Norton Family Premier ($49.99 on Norton) delivered the best mix of web filtering, location tracking and app management, particularly when installed on Android devices. (The iPhone version of Norton Family Premier was limited by comparison, but still offered just enough web filtering to make it worthwhile.)

Norton's parental-control app beat out PhoneSheriff ($89 a year), which is a good alternative on Android, particularly for monitoring texting. Parents with many kids to manage might appreciate the simple setup of ESET Parental Control for Android ($30 a year), which lets you control an unlimited number of devices.

Norton and ESET also make antivirus software, and many antivirus products have parental controls built in. To see how well those controls stack up against the stand-alone services, please read The Best (and Worst) Antivirus Software for Parents.

[Editor's Note: As of March 5, 2018, the maker of PhoneSheriff and MobileSpy, Retina-X Studios, stopped taking new orders for either app. This followed a break-in into Retina-X's servers, the latest of several. The attacker is believed to be a hacker opposed to the distribution of Retina-X's software, which some people consider spyware or an intrusion of privacy because it can be used to monitor the activities of adults as well as children.

In its announcement, Retina-X did not say if or when it would resume sales of MobileSpy or PhoneSheriff. We've removed both apps from the carousel above for the time being, and will reinstate them if they become available again.]

How We Tested and Rated

Evaluation Criteria

We focused our testing on apps that emphasize setting up filters and limits before your child uses the phone, instead of merely tracking activities after the fact. In evaluating these products, we took the following criteria into account:

  • Installation: How easy is it to install and configure each app on a smartphone?
  • App Management: Since most of the time spent on smartphones is within an app, not a browser, which program lets the parent review all the apps on a child's device and block or limit app usage?
  • Filtering: Which tools does each app offer, and how well do those tools restrict kids' access to inappropriate content online?
  • Texting Management: With kids doing most of their communicating through text messages, we looked at the features for monitoring messaging. Do the apps let you review the content of your child's texts? Can you block a contact and be alerted when your child adds a new contact? Can you block messaging apps altogether?
  • Location tracking: Does the app keep a log of where your child has been and, more importantly, give you the ability to locate your child in an emergency?
  • Price: How much does the service cost annually? How many devices can you monitor or control?

We also looked into whether these services let parents monitor kids' activities on social media, although in most cases, the features we found were pretty limited. You either need to "root" a device — which we do not recommend — or have your child hand over his or her username and password.

We tested each Android and iOS app twice, from installation to testing to uninstall. We monitored activity and managed settings on a MacBook Pro, and used both iOS and Android phones to send texts or call the Android device we were monitoring.

Both Norton Family Premier and Qustodio for Families Premium feature iOS versions, which we tested and rated separately from their Android counterparts. Apple imposes limits on what third-party apps are able to control, and while some of those restrictions have been eased in recent iOS updates, the Android platform still enables far more robust parental monitoring controls.

None of the services tested for iPhone were able to effectively limit how much time a child could spend on their iPhone; we also couldn't monitor texts or block specific contacts. You can monitor more on the iPhone than you could a couple of years ago, but Android remains a better platform if you want more control over how your children are using their mobile devices. Parents of kids with iOS devices would be well-advised to familiarize themselves with the parental-control options available in iOS 10's Settings app.

What We Didn't Include

Parental-control apps for mobile devices work best when they're part of a comprehensive approach to teaching your kids about behaving responsibly online. That means talking to your kids about what they should and shouldn't do with their mobile devices, clearly communicating how you expect them to act and making clear that you will be monitoring what they do with their phones.

For that reason, we avoided testing apps that run only in stealth mode on a child's phone. Products such as WebWatcher and mSpy both tout this capability, but we're aware that some people use such services to spy not on their children, but on their spouses or on other adults, which is illegal in most U.S. jurisdictions.

Both PhoneSheriff and Mobile Spy allow the installer to turn off user notifications and remove the app icon from the list of installed apps, leaving the phone user generally unaware that he or she is being monitored. Neither app is offered in the official Google Play Store for Android apps, meaning that users will have to "sideload" them, a practice that we do not recommend for security reasons.

Both PhoneSheriff and Mobile Spy have reportedly been used by jealous spouses or lovers to spy on adults, although we have not been able to confirm that. However, both apps will still show up in the apps list in system settings; adults worried that they are being spied upon should check that menu.

We also did not consider apps that offered the ability to record phone conversations, because state laws vary on the legality of recording someone without his or her consent.

Norton Family Premier (Android): Best Overall Parental-Control App

Norton Family Premier packs just about any feature a parent could ask for into its mobile-device-management offering, giving you control over multiple features on multiple devices. You won't be able to monitor every aspect of how your kids are using their Android phones, but with the web-filtering, app-monitoring and location-tracking features, you'll have enough control to remind them to responsibly use their mobile devices.

Only ESET Parental Control and Qustodio approach Norton's ability to help you monitor multiple devices and multiple children. It's easy to set up age-appropriate profiles on Norton Family Premier, and even easier to port them across multiple devices.

The web filters in Norton Family Premier can keep your child away from questionable websites, and it's easy to set times for when it's OK to use an Android phone. (One complaint: Norton's offering would be more powerful if it let you block out times for specific apps.) But Norton's best feature may be its location-tracking capabilities, which give you a fairly accurate picture of where your children (and their phones) happen to be.

Like ESET, Norton is at heart an antivirus maker. Norton Family Premier comes free if you spring for Norton's most expensive antivirus suite, Norton Security Premium. That product nominally costs $90 per year, but it's often discounted for as little as $60. At that price, getting Norton Family Premier and Norton's excellent antivirus protection for $10 more is kind of a no-brainer.

Don't expect to be able to block specific callers and texters with Norton Family Premier, and the app's text-monitoring features are a little overbearing. Still, the overall mix of features makes this the best choice for parents who want to stay on top of what their kids are doing with their smartphones.

PhoneSheriff: Runner-Up

[EDITOR'S NOTE: As noted above, PhoneSheriff is not currently being offered for sale. We do not know if or when it will be sold again.]

Of all parental-control services we tested for Android devices, PhoneSheriff came out near the top, bested only by the Android version of Norton Family Premier. For $89 a year ($49.95 with coupon code: SAVE40), it provides the tools you need to manage how your child uses up to three mobile devices while also logging a wealth of information — perhaps even too much — about what your kid is doing on that phone.

While it's one of the tougher programs to install, PhoneSheriff offers a robust set of features and makes them relatively easy to use. It's an effective way to monitor all age groups, though its features come in particularly handy when it comes to preteens.

PhoneSheriff has a great suite of features. You can review apps installed on your child's phone and block the ones that don't pass muster. You can set time limits both via the PhoneSheriff admin panel and on the device itself. PhoneSheriff reveals every text your child sends, and you're able to block people, setting up both whitelists and blacklists of phone numbers. The service also logs your child's location, and a geofencing feature will alert you should your child leave a specified area. 

PhoneSheriff does just an adequate job at monitoring web browsing, and it doesn't offer social-media monitoring. The services it does provide, however, are stellar and provide an easy way to make sure that your child's texting and app use are aboveboard. Smart features like a panic button that lets your child send you an alert with his or her location will add to your peace of mind.

ESET Parental Control for Android: Best Value

Parents concerned with how much time their kids spend on Android devices and the apps and websites they're using may want to consider ESET Parental Control. This parental-control app prizes simplicity and easy setup, though you give away some of the more precise control you'd enjoy with the Android versions of Norton Family Premier and PhoneSheriff.

When you configure ESET, you can automatically set web filters based on subjects, which are easy to adjust with a thumbs-up/thumbs-down interface in the app's parent portal. Adding websites that might otherwise be blocked is a little less intuitive, though you can easily OK emailed requests from your kids.

Time limits, too, are easy to institute, whether it's a limit on how long kids can use their Android phones or how much time they can spend on apps that you slap with a Fun & Games label. However, that time limit applies to all Fun & Games apps — you can't place different limits on different apps. ESET is particularly strong when it comes to letting you quickly review and approve which apps are installed on your child's phone.

ESET can track a phone's location, though it lacks pinpoint accuracy and a location log. You'll also want to look elsewhere if you want to manage your child's social network activity or phone calls, since the app doesn't offer those features. Still, ESET offers a valuable app-usage report, and supports an unlimited number of Android devices. If you want a straightforward parental-monitoring tool for multiple devices, ESET's approach to setting up web filters and time limits has some appeal.

ESET Parental Control for Android is bundled into ESET Multi-Device Security Pack, which can cost as little as $69 for three users for a year. However, it's different from the parental controls built into other ESET antivirus products, including ESET Internet Security and ESET Smart Security Premium.

Qustodio for Families Premium: Good for Multidevice Homes

While it can't match the robust feature set of Norton Family Premier or PhoneSheriff, Qustodio is a worthwhile alternative, especially if you live in a household where there are more than just Android phones to manage. Qustodio costs $55 a year for five devices, including Macs and PCs. For 10 devices, it's $97, and for 15, it's $138. Qustodio also offers a tool for iOS devices (included in this pricing), which we reviewed separately because parental-control capabilities are much more limited on the iPhone than they are on Android phones.


Qustodio is easy to set up, and managing filters for multiple users is a snap. The service really shines with its ability to set time limits for individual apps. It's easy to monitor texts from Qustodio's admin panel, and you can block texters and callers directly from the screen where you review text and call logs. Qustodio's website-restriction and location-tracking features are limited, but overall it's a good value.

Net Nanny for Android: Best for Single-Device Homes

Of the services I tested, Net Nanny was one of the best at filtering Web content, right up there with ESET Parental Control. Net Nanny reliably masks profanity, blocks inappropriate sites and images, and gives you the option of warning your child about a site's content instead of blocking it entirely.

Reviewing and blocking apps is also handled with aplomb, and you can even temporarily unblock an app for a set period of time. I wish that Net Nanny had let me limit usage on a per-app basis, but its management tools are otherwise solid. 

You can't set up a geofence, and you're unable to remotely lock a device the way you can with PhoneSheriff. Net Nanny also doesn't offer much insight into your child's texting habits, but the ability to monitor social-media activity is built into the $60-a-year Family Pass.

Norton Family Premier (iOS): Best iPhone Web Monitor

Because of the restrictions Apple puts on mobile device managers for iOS devices, finding a program that can monitor what your kids are doing on their iPhones can mean forgoing the features that are most important to you.

If you're primarily concerned about keeping your kids away from dubious content on the web, the iOS edition of Norton Family Premier ($50 a year) is an excellent choice. Norton's iOS offering provides robust filtering tools, whether you use the iPhone's built-in Safari browser or Norton's own browser. Age-based filters make it easy to get it up and running, and you can further customize filters or whitelist sites.

Norton's iOS app offers other nice features as well, such as location-tracking tools that do a decent job of finding out where your child is.

The iOS app also provides daily and weekly reports on which sites your child visited, with links that make it easy for you to review just what your kids are up to when they surf on their iPhones.

However, Norton doesn't allow you to set time limits, either for specific apps or overall. You can't block or restrict which apps your child can use (unless you use the iPhone's built-in restriction), and, as on other iOS parental control apps, you can't block specific contacts.

As mentioned above, Norton Family Premier comes bundled into Norton Security Premium, the company's top-tier antivirus program that lists for $90 per year but is often discounted to be as low as $60.

Lock2Learn: Limited App Manager


[NOTE: We can no longer recommend Lock2Learn, as it may have gone out of business. We noticed that the Lock2Learn website was offline in mid-November 2017, but the person who answered the phone at the Lock2Learn offices assured us that the site was undergoing an overhaul and would be back up soon. As of mid-February 2018, the site's domain has been taken over by another company, our emails to the Lock2Learn contact address bounce and the app will not install on newer versions of Android software.]

Lock2Learn stands out from the other products here, as it's not strictly a monitoring product. But it does give you some control over your child's mobile devices by letting you restrict app access and screen time. There's also a promising educational twist: Lock2Learn will lock a device at intervals you select, and the only way your child can regain access is by answering a series of questions about English or math.

That said, there's no way to limit the time kids can spend on specific apps or to disable a phone entirely at night. And I was uncomfortable with just how much personal data Lock2Learn requires. Still, this is a low-cost way to limit app usage — the Android app is free, and additional question packs cost $2.

My Mobile Watchdog: Limited Control Features

Norton Family Premier, PhoneSheriff or ESET offer more parental-control features than My Mobile Watchdog. Still, the $100-a-year service offers some appealing capabilities and lets you manage up to five devices.

App-management features in My Mobile Watchdog lag behind what you'll find elsewhere, but there are nice little touches, like the ability to temporarily block an approved app in case your child is spending too much time gaming when he or she should be concentrating on homework. You can also make sure that newly installed apps won't open until you've OK'd them.

My Mobile Watchdog does a good job with text monitoring, too, alerting you when a unauthorized contact texts your child, or if your child receives a texted image. Approving and blocking contacts is cumbersome, though. 

I was disappointed with My Mobile Watchdog's location features. Location-logging data was infrequently updated, and geofencing was impossible to set up. The web-filtering tools are unrefined, and you can only block specific sites one by one instead of restricting entire categories of websites. Still, I do like the way My Mobile Watchdog breaks down a child's mobile activities on its dashboard.

Qustodio Parental Control for iPhone and iPad: Expanded But Still Limited

As solid as Qustodio’s parental control offerings are on other platforms, this app for monitoring iOS devices is pretty lackluster. In part, that reflects the restrictions Apple puts on third-party monitoring apps, but that doesn't fully explain the flaws in Qustodio's iOS offering.

The app is difficult to install, and its location-tracking features aren't as accurate as I'd like to see. I also would prefer text alerts about my child's browsing activity, which would be timelier than the emails Qustodio's app sends.

That said, the activity timeline gives you a fairly thorough look at your child's online activity, at least for the apps Qustodio is able to monitor on iOS devices.

The web-filtering tools are impressive, even if they only work for Qustodio's own mobile browser. And Qustodio has added some time-management features to its iOS app, which, while limited, are still welcome.

There's not enough functionality here to make this a worthwhile parental control option in iOS-exclusive homes, but if you've got multiple devices on multiple platforms to manage, this iOS offering broadens Qustodio's reach.

Mobile Spy Basic Version 7: Focuses on Activity Logs

[EDITOR'S NOTE: As noted above, Mobile Spy is not currently being offered for sale. We do not know if or when it will be sold again.]

Mobile Spy ($100 a year for up to three devices) takes a different tack from the other services reviewed here, with its most robust features focused on logging your child's activity. That's a fine approach if that's what you're looking for in parental-control software, but realize that you won't have much say in how your child uses the mobile device. You can only block apps, not set time limits, and social-media monitoring only works on a rooted device. I was also unable to block callers, though I could set an alert for when a specified number contacted my child's phone.

That said, Mobile Spy has robust location-tracking and geofencing features. You can receive alerts whenever the device goes past a distance you've set or if the device is used in the vicinity of locations you specify. To take advantage of those features, though, you'll need to contend with a difficult installation process — easily the most frustrating among the services I tested.

    MM Guardian seemed like a great app, but my 14-year-old son uninstalled it easily. (It doesn’t help that there are all kinds of how-to’s on the Internet.) I am waiting for a response from the company on what they’re going to do. Unfortunately, it seems most kids will always be more tech-savvy than parents.

    Kaspersky Safe Kids.

    It has free and premium features. The premium license is less than $20 a year, and is free to download.

    I can block either by certain times, or by usage time. It can be set up to either block completely, or just warn the child. You can either ban certain apps, or ban all but the ones you've whitelisted.

    If your child tried to access an app not allowed on their device, it shows up as a "request" on your own device, and you can approve it there.

    It's very powerful for its price point, but the UI could use a bit of polish. If you're moderately competent them you can easily figure it all out, though.
