The verdict
A competent screen-time and app-blocking tool for parents who need schedules, daily limits and a lockdown button across a mixed iPhone-and-Android house. It is not accountability software: no partner report, no mutual consent, no texts or calls. Skip it if you want the Covenant Eyes model, if you have more than ten devices, or if you will not plug each iPhone into a computer to make blocking actually block.

Kidslox launched in 2014 and now sits on 39,789 App Store ratings at 4.3, and 36.3K Google Play reviews at 4.1. Those are large numbers for a category where most products never clear four figures. Kidslox is also one of two firms - Qustodio was the other - that complained to the European Commission in April 2019 that Apple abused its dominant position by launching Screen Time while blocking competing parental control apps from shipping updates. That matters, because most of what Kidslox cannot do on iPhone traces back to the platform limits the complaint was about.
The product is a parental control console: daily screen-time limits, up to five schedules for homework, dinner, bedtime and family time, individual app blocking, a web filter built on a blocklist of over 4 million URLs, GPS with arrival and departure alerts, and one-tap Lock and Child modes. Newer additions include screen-time rewards for chores, AI summaries of visited sites, nude-image detection in the gallery, and limited social monitoring of YouTube, Instagram and TikTok. One account manages every device from the app or a browser, and iOS devices can be supervised from Android and the reverse.
It is worth being precise about the category, because this market uses one word for two products. Covenant Eyes, Ever Accountable and Accountable2You are accountability tools: an adult volunteers to have activity reported to another adult who has agreed to look at it. Kidslox is control software: a parent sets rules on a child's device and the child cannot change them. No partner, no shared report, no mutual consent. An adult looking for help with his own phone will find nothing here.
The interesting part is not the feature list but the gap between the marketing and the vendor's own support pages, which contradict its App Store copy in at least two places.
✓ The good
- Genuinely cross-platform supervision - the vendor states you can supervise iOS devices from Android and vice versa, which little else at this price handles cleanly in a mixed-phone household.
- Flat device pricing above the entry tier - Family and Guardian cover up to 10 child devices and unlimited parent devices at no additional cost, so a fourth child costs nothing.
- A real free plan rather than a trial wall - after the 3-day trial the account drops to Free, which still supervises one child device and allows five manual mode switches a day indefinitely.
- Schedules and a lockdown button are the right primitives for younger children - five custom schedules plus instant Lock and Child modes covers homework, dinner and bedtime without nightly negotiation.
- No ads and no disclosed third-party sharing - the App Store description says Kidslox contains no advertisements, and Google Play Data Safety says no data is shared with third parties and data is encrypted in transit.
- Screen-time rewards tie minutes to chores - extra time is granted for completed homework and household tasks, turning the limit into a currency rather than a punishment.
✗ Watch out
- On iOS without Advanced Features, blocked apps are not blocked - the vendor states blocked apps are cut off from the internet but are still available, so the icon remains and offline apps still run.
- Enabling Advanced Features on an iPhone needs a desktop computer, a USB cable and iTunes - the vendor's own known-issues page confirms iTunes is required and troubleshoots cables and ports.
- Deleting the app icon on iOS defeats daily limits - Kidslox states restrictions still run but Daily limits will not work until it is reinstalled, so the headline feature is the easiest to disable.
- Android gets features iOS does not - per-app time limits, app usage statistics and TikTok viewing history are named as Android capabilities, so two children on two platforms are not equally supervised.
- No SMS or call monitoring at all - social monitoring covers YouTube, Instagram and TikTok only, and is excluded from the Family plan, so it exists on the top tier alone.
- Prices are absent from kidslox.com and the terms disclaim the core promise - Kidslox states it shall have no liability in relation to any failure by the App to restrict or control access.
Best for
- Parents of primary-school children on shared tablets
- Mixed iPhone and Android households
- Families wanting schedules more than surveillance
- Budget-conscious homes with up to ten devices
Avoid if
- Adults seeking accountability partner reports
- Households with more than ten devices
- Parents needing text and call oversight
- Anyone unwilling to use a desktop for setup
What Kidslox is
Kidslox is a subscription parental control app for iPhone, iPad and Android, managed from a parent app or any web browser. On iOS it installs an official Apple Mobile Device Management profile, which is what allows a parent to change settings remotely; on Android the equivalent is granting Administrator privileges. The feature set covers daily limits, five schedules, app blocking, a 4-million-URL web filter with SafeSearch and YouTube Restricted Mode enforcement, GPS with geofence alerts, and Lock and Child modes behind a parent PIN.
One account covers a family rather than a child. The App Store description says one paid account controls up to 10 devices, and support adds that parent devices are unlimited. It is aimed at parents, not adults managing their own habits. The App Store developer of record is Kidslox Trading Limited; the terms name Kidslox, Inc., a Delaware company, under Delaware law.
Cross-platform control from a company that took Apple to Brussels
The App Store copy calls Kidslox the first multi-platform parental control, and the practical form of that is a parent on an Android phone locking an iPad, or a parent on an iPhone locking a Samsung. In a house where adults and children sit on different platforms, that rules out much of the competition, which assumes one ecosystem. Kidslox charges the same regardless of the mix, and the ten-device allowance covers phones and tablets together.
The company also has a public record on why iOS control is hard. On 30 April 2019 Kidslox and Qustodio jointly complained to the European Commission Directorate-General for Competition that Apple had launched Screen Time in iOS 12 as a pre-installed, non-removable service, blocked competing parental control apps from releasing updates, terminated non-compliant developers, and reserved exclusive technologies for itself. The Kidslox chief executive said Apple took the best pieces and best practices from existing parental control apps and brought no tangible innovations to market. That explains most of the iOS caveats below.
App blocking, and what blocking means on each platform
The marketing line is that Kidslox blocks individual apps on both Android and iOS. The vendor qualifies it on its own how-it-works page: the iOS app blocking feature disables internet access, and without Advanced Features enabled, blocked apps are cut off from the internet but are still available. On a standard iPhone the blocked app still sits on the home screen, still opens, and still works offline.
Advanced Features close the gap - blocking all apps, hiding blocked apps, anti-tampering, preventing app deletion, choosing which apps survive Lock Mode, and keeping location alive during Lock Mode. All six work on Android without extra setup. Getting them onto an iPhone means a desktop installer, a USB connection and iTunes, which the vendor's known-issues page confirms is required. That barrier is where a large share of the one-star reviews originate.
Web filtering by blocklist rather than by category
The filter rests on a blocklist of over 4 million URLs covering gambling, violence and adult content, backed by SafeSearch locking on Google and Bing and YouTube Restricted Mode. Parents can add their own sites, and there is a nuclear option to disable internet access entirely. Newer additions include AI summaries of visited sites and detection of nude images in the gallery.
What is absent is category-level control. There is no panel where a parent switches off social media but leaves streaming on; the model is the Kidslox list plus whatever you add by hand. For a family worried about specific sites that works. For a family that wants policy rather than a list, it is thinner than Canopy or Qustodio.
Limits, schedules and the tamper problem
Daily limits plus five schedules is the core, and the design is sound: a fixed allowance, named windows where the device is unavailable, and extra minutes for chores. Modes switch with one tap behind a Kidslox PIN, which the App Store description frames as stopping clever kids from changing the restrictions.
The vendor is honest about where that ends. Its support article on a child deleting Kidslox on iOS states that restrictions will still run in the background, but Daily limits will not work until the app is reinstalled. So on an iPhone without Advanced Features, dragging one icon to the bin turns off the feature most parents bought, while leaving the profile in place. The reviews show the reverse problem: the loudest recurring adult complaint is not children escaping but parents unable to get the app and its VPN profile off a device.
Pricing
Free
Free
Runs indefinitely after the 3-day trial ends. Supervises one child device and allows the mode to be switched manually five times a day; Kidslox states all other features are unavailable.
Premium, monthly
$3.99 to $7.99 per month
The App Store lists monthly items at $3.99, $5.99 and $7.99, plus a legacy item named Kidslox Premium at $2.99. Kidslox names three paid tiers - Basic, Family, Guardian - but does not print which price buys which.
Premium, annual
$49.99 or $79.99 per year
Two annual items, both labelled Kidslox - 12 months. Google Play shows the same pair as $54 and $79. $49.99 works out at $4.17 a month against $5.99 billed monthly.
Premium, fixed term
$19.99 for 3 months, or $19.99 for 6 months
Both terms carry the same $19.99 on the App Store: $6.66 a month over three months, $3.33 a month over six. Reading the list carefully is worth about $20 a year.
Kidslox does not print prices on its own site. The homepage advertises a 20% back-to-school sale and a 3-day free trial with no figures, the pricing page loads its table only inside the signup flow, and support says the price varies by country of residence. The only exact published numbers come from the app stores.
The US App Store in-app purchase list runs: monthly items at $3.99, $5.99 and $7.99, a legacy item named Kidslox Premium at $2.99, three months at $19.99, six months at $19.99, and two twelve-month items at $49.99 and $79.99. Google Play shows the annual pair as $54 and $79 - same product, two storefronts, two sets of numbers.
The arithmetic rewards annual and punishes inattention. $5.99 a month is $71.88 over a year against the $49.99 annual item, a $21.89 difference, assuming the two are the same tier. $7.99 a month is $95.88 against $79.99, a $15.89 difference. And both fixed-term items are $19.99: $6.66 a month over three months, $3.33 over six - the same money for twice the coverage.
How it scales matters, because Kidslox has historically been described as device-priced. It is not a per-device multiplier but a tier gate. Free supervises one child device with five mode switches a day. Basic Premium is paid and still supervises only one child's device, with a limited feature set. Family Premium unlocks everything except Social Networks monitoring. Guardian Premium unlocks everything and, in the vendor's words, lets you add 10 supervised devices and an unlimited number of parent accounts. So the fourth and fifth child device cost nothing - up to the tenth, after which one account cannot cover you.
Two contradictions belong here rather than in a footnote. The App Store description says one paid account allows you to control up to 10 devices, while support says the paid Basic option supervises only one child's device; both are Kidslox describing a paid account. And the App Store description still explains that a Lifetime subscription does not auto-renew but gives ongoing access for a one-off payment, yet no lifetime item appears in the current in-app purchase list, whose longest term is twelve months.
Where Kidslox falls behind
Not accountability software, whatever the listing says. No partner, no report emailed to a friend or spouse, no mutual consent. Covenant Eyes sends screen activity to a person the user chose; Accountable2You sends a report to a partner. Kidslox sends everything to a parent dashboard and nowhere else.
The iOS ceiling is real and the vendor says so. Blocked apps stay visible and launchable without Advanced Features, per-app limits and app usage statistics are Android-only, and daily limits stop if the child deletes the icon. All of it is disclosed by Kidslox rather than dug out of a review, to its credit - but an iPhone household buys a weaker product at the same price.
Ten devices is a hard cap. For a family with several children, spare tablets and a couple of hand-me-down phones, ten goes quickly. Covenant Eyes publishes unlimited devices for up to ten individual users on every tier - a different shape of allowance for the same family.
No SMS, no calls, and social monitoring gated to the top tier. Kidslox covers YouTube, Instagram and TikTok, and its own plan comparison excludes Social Networks monitoring from Family. A parent whose real worry is who is messaging their thirteen-year-old is buying the wrong product.
A 4.3 average with a very loud minority underneath. The aggregate rests on 39,789 ratings and is the honest headline, but recent one- and two-star reviews cluster on two themes: parents who cannot get Kidslox or its VPN profile off a device, and support that answers via chatbot before a human replies days later. A third cluster is children review-bombing the app for working as designed. Read the low reviews with that separation in mind.
Kidslox vs. Bark vs. Qustodio vs. Canopy
These four solve four problems, and the choice is mostly about which one you have. Kidslox is a time-and-access manager: schedules, daily limits, an app blocker, a URL blocklist, GPS. Bark is a content monitor: it reads texts, email and social platforms and alerts a parent to specific risks rather than shutting the device off. Canopy is a filter: on-device AI that blocks explicit imagery in real time, including in apps a blocklist never sees. Kidslox does not do what Bark does, and it filters by list where Canopy filters by looking at the image.
Qustodio is the nearest true competitor, which is fitting given the two companies filed the 2019 Commission complaint together. Qustodio goes deeper on reporting and category-based web rules; Kidslox is simpler and better at the mixed-platform case where a parent on one operating system supervises a child on the other. For granular category policy, Qustodio. For a lockdown button and five schedules both parents can operate, Kidslox.
Covenant Eyes is not in this bracket at all. It runs at $18/mo or $198/yr, sends screenshot-based Screen Accountability to a partner the user chose, and is built for consenting adults, with its own disclosed limits - iOS screenshots restricted to Safari, nothing on Chromebooks or Smart TVs. A household needing both a child screen-time manager and adult accountability needs two products; Kidslox answers the first half.
The bottom line
Kidslox does one job well and says out loud where it stops, which is more than most of this category manages. For parents of younger children in a mixed iPhone and Android house needing schedules, daily limits and a panic button across up to ten devices, the $49.99 annual tier is fair value and the free plan is a real way to try it on one device. But iOS wants a desktop, a cable and iTunes before blocking really blocks, the ten-device cap is absolute, there is no text or call oversight, and it is control software rather than accountability software. Buy it as a screen-time tool; buy something else if you want a report going to another adult.
Alternatives to Kidslox
Frequently asked questions
Does Kidslox charge per device?
Not above the entry tier. Support states the Family and Guardian Premium plans take up to 10 child devices and unlimited parent devices at no additional cost, while Free and the paid Basic plan each supervise one child device. It is a tier gate, not a multiplier. Note that the App Store description says a paid account controls up to 10 devices, which does not match the support description of Basic.
How much does Kidslox cost?
Kidslox does not print prices on its own site, and support says the price varies by country. The App Store in-app purchase list shows monthly items at $3.99, $5.99 and $7.99, a legacy $2.99 item, $19.99 for three months, $19.99 for six months, and twelve-month items at $49.99 and $79.99. Google Play shows the annual pair as $54 and $79, after a 3-day trial.
Is there a lifetime plan?
The App Store description still describes one, saying a Lifetime subscription does not auto-renew but gives ongoing access for a one-off payment. No lifetime item appears in the current in-app purchase list, whose longest term is twelve months, and Google Play lists annual subscriptions only. Treat lifetime as legacy unless a live purchase screen offers it.
Does Kidslox work the same on iPhone and Android?
No, and the vendor says so. On iOS it installs an Apple MDM profile; on Android it uses Administrator privileges. Without Advanced Features on iOS, blocked apps are cut off from the internet but are still available, and blocking all apps, hiding them, anti-tampering and preventing deletion all need setup Android does not. Per-app limits, app usage statistics and TikTok history are named as Android capabilities.
Can my child get around Kidslox?
On iOS, deleting the app icon breaks the main feature: Kidslox states restrictions still run in the background, but Daily limits will not work until it is reinstalled. Advanced Features add anti-tampering and prevent deletion, but enabling them on an iPhone needs a desktop, a USB cable and iTunes. The App Store description also notes Kidslox cannot be added to a device already carrying an education or business MDM profile.
Is Kidslox an accountability app in the Covenant Eyes sense?
No. Accountability rests on consent and a second pair of eyes: an adult agrees to have activity reported to a partner who has agreed to look at it. Kidslox is parental control - a parent sets rules a child cannot change, and everything reports to the parent dashboard alone. For the other model, look at Covenant Eyes, Ever Accountable or Accountable2You.
