Skie vs MMGuardian Phone and MMGuardian app

A Samsung phone with MMGuardian built in, or the MMGuardian app, against device-owner control on any Android brand.

Facts checked 12 November 2026 · Pervasive Group Inc (MMGuardian), United States (New Jersey)

Summary

MMGuardian sells two things: the MMGuardian Phone, a Samsung Galaxy with its parental controls pre-installed at system level, and MMGuardian apps for a child's existing Android phone, tablet or iPhone. The phone is sold without a mobile plan, so you add your own carrier. The controls include message monitoring, web filtering, location, contact blocking, app blocking and screen time limits. Skie is software on any Android 12 or newer phone or tablet, with no hardware and no mobile plan.

Skie offers a similar device-level lock on a phone or tablet the family already owns, with geofences, SOS and schedules, and without reading the child's messages.

Side by side

What you are comparing	MMGuardian Phone and MMGuardian app	Skie
What it is	A Samsung phone with MMGuardian installed at system level, plus MMGuardian apps for a child's own Android or iPhone, per the maker.	Android device management software for families. It runs as the Android device owner. Skie is software, not a phone.
Main audience	Parents of children aged about 7 to 17 who want monitoring as well as blocking, with controls that loosen as a child grows.	Parents of children with a phone or tablet. Schools, hostels and organisations use the separate Skie for Enterprise product.
Platforms	Phone: Samsung Galaxy (A17 listed, running Android 16). App: Android, iPhone and iPad, plus a reduced-price Android tablet app.	Any Android 12 or newer phone or tablet. No iOS.
Do you have to buy hardware from them	No if you use the app. Yes for the MMGuardian Phone: 289 dollars with a monthly service fee, or 259 dollars with a yearly plan, per the A17 page.	No. Skie sells no hardware. The family uses a device it already owns or buys its own.
Works on devices you already own	Yes with the app, on Android and iPhone. The system-level phone controls apply only to the MMGuardian Phone.	Yes. Any Android 12 or newer phone or tablet, after it has been freshly set up or reset once to become managed.
Mobile plan or carrier included	No. The phone is unlocked and works on major US carriers. The maker also sells a US Mobile SIM kit with an unlimited talk and text plan with 2 GB of data from 10 dollars a month.	No mobile plan or SIM. The family keeps its own carrier. Wi-Fi-only tablets work for most features.
Level of control on Android (device owner or app level)	System level on the MMGuardian Phone. App level on the app version, which the maker says is more limited.	Android device owner, so the rules are enforced by Android itself.
Can the child remove it or reset around it	On the phone, the maker says safe mode, factory reset, uninstall, VPNs and side-loading are blocked, and that incognito browsing does not stop the web filter. Independent coverage notes the app-only version can be defeated by a factory reset, with the parent alerted.	Built to be tamper-proof. Factory reset from Settings, safe mode, developer options and adb are blocked, and Skie cannot be uninstalled or force-stopped. Android's Factory Reset Protection is on, so a wiped device asks for the Skie organisation's Google sign-in, which only Skie holds. If anything ever did get through, the parent is alerted immediately, down to the exact device.
App control	Allow or block any app from Google Play. App usage reports.	The parent chooses which apps work. Apps are hidden or suspended, not deleted, so data returns when they are allowed again. An app installed later that is not allowed is removed silently. The Play Store can be shown or hidden.
Web filtering and safe search	Web filter included, working in incognito mode on the phone.	A filtering DNS is locked on the device, so it applies on any Wi-Fi or mobile data. Adult-site blocking with a locked filter, SafeSearch and YouTube restricted mode forced in Chrome, incognito blocked, and more than 50 other browsers, VPN apps and proxy apps always blocked.
Schedules, bedtime or school-hour modes	Phone lock and screen time limits are listed. Schedules are part of the screen time controls.	Yes. Study and bedtime schedules with days, start, end and allowed apps. Windows can run overnight and the device switches app sets on its own.
Location, geofences and SOS	GPS tracking that the maker says kids cannot turn off. Geofences and an SOS button are not confirmed on the pages I read.	Live location and trail, geofence alerts, a go-to directions button, and an SOS button that calls the emergency number.
Lost or stolen device handling	Phone lock is listed. Dedicated lost-mode or police-report tools are not publicly documented.	Lost mode locks the device, shows a contact message, tracks it and builds evidence for a police report (IMEI, serial, SIM details, location trail). Mark it found to return to normal. Remote erase is not available yet.
Replace or reassign a device	App subscriptions can be moved from Android to iPhone with no refund. Phone replacement is not publicly documented.	Replace a device and the child keeps their group, settings and history. The old seat is freed.
Alerts and who gets them	AI-powered safety alerts on texts and pictures go to the parent app.	A breach centre on the parent dashboard shows missing check-ins and any protection that changed. Email alerts to parents are not available yet; the team is working on it.
Roles and organisation structure	A parent app on the parent's phone. A family plan covers up to 5 child devices.	A parent dashboard in the browser. Both parents can have access. One device per child.
Screen time reports and per-app limits	Yes. Screen time limits and app usage reports are listed.	Not available yet: per-app time limits and screen time reports. Schedules and allow lists cover part of the need today, and the team is working on the rest.
Message or social media monitoring	Yes. The maker lists message monitoring, including deleted messages, and social media monitoring on its app. Skie does not do this by design.	Skie does not read messages or call logs and does not record audio or video. There is no hidden mode: the phone shows it is managed.
Kiosk or single-app lock	Not publicly documented. Phone lock is available.	Yes. Full-screen kiosk mode, and a one-app allow list also locks a device to one app.
Tablet support	Yes through the app: an Android tablet app at a reduced price, and iPad. There is no MMGuardian-branded tablet.	Yes. Phones and tablets are treated the same.
Pricing model	Phone: 289 dollars plus 9.99 dollars a month, or 259 dollars plus 120 dollars for a year. App: 4.99 dollars a month for one phone or 9.99 dollars for a family of up to 5; yearly options listed. 14-day app trial.	Pricing is on request.
Countries available	The phone is described as US only. The app pricing page offers regional versions for the US, Australia, UK, Canada, France, Spain and Italy.	Worldwide, subject to local law, wherever the device has Google Play services.
Setup effort	The phone arrives set up; the maker says the parent logs in and is guided. The app takes about 15 minutes.	The device must be freshly set up or reset once and any Google account removed. The parent then provisions it with the Skie Provision app on Google Play, or with a computer and cable. A new device model goes through a one-time model review.
Data and privacy approach	Company based in New Jersey since 2012. The maker's pitch includes reading messages; data location is not publicly documented here.	Data is stored in an India region (Mumbai). Skie provides the controls; the family decides on notices and consent.
Best suited for	A US family that wants message monitoring and detailed controls on a purpose-built Samsung.	Yes. Phones and tablets are treated the same.

As of November 2026, the maker's A17 page lists the MMGuardian Phone at 289 US dollars plus 9.99 dollars a month, or 259 dollars plus 120 dollars for a year, with an airtime plan from your own carrier extra. The app is listed at 4.99 dollars a month for one phone or 9.99 dollars for up to five child devices. Skie is software for a device you already own and pricing is on request. Skie includes no mobile plan, so the family keeps its own carrier.

What MMGuardian is and how it works day to day

MMGuardian is a long-running US family safety company with two products. The MMGuardian Phone is a Samsung Galaxy, currently the A17, that arrives with the MMGuardian controls installed at system level. The MMGuardian apps install on a child's existing Android phone, tablet or iPhone.

The parent logs in on first start and is guided through the controls, and afterwards manages everything from the MMGuardian parent app. The maker lists message monitoring, safety alerts, location tracking, contact blocking, phone lock, app usage reports, screen time limits and a web filter. The child sees a normal-looking smartphone with the parent's restrictions applied.

The age guidance is 7 to 17, with controls loosened over time. The maker's own review page rates the phone highly and notes it operates in the US only and that the interface takes time to learn.

What it costs in total against Skie on a device you already own

As of November 2026 the phone costs 289 dollars plus a 9.99 dollar monthly service, or 259 dollars plus 120 dollars for one year, and an airtime plan from your own carrier is required. The maker estimates the first-year cost including a data plan on a separate page; the figures change with promotions. If you prefer a cheap plan, it also sells a US Mobile SIM kit with unlimited talk and text and 2 GB of data from 10 dollars a month.

The app route is cheaper: 4.99 dollars a month for one child phone, 9.99 for a family plan of up to five devices, with a 14-day free trial, and a reduced-price Android tablet plan. It runs on a device you already own, but it works at app level and does not carry the system lock of the phone.

Skie is closer to the phone's level of control but without the hardware line. The family uses a device it already owns, Android 12 or newer, and pricing is on request. Skie includes no mobile plan, so the airtime cost is the family's own either way.

Controls compared: apps, web, location and SOS

On apps, MMGuardian lets the parent allow or block any app from Google Play and view usage reports and limits. Skie lets the parent choose which apps work, hides or suspends the rest, removes later installs that are not allowed and can hide the Play Store. Skie does not yet have per-app time limits or usage reports, and the team is working on them.

On the web, both filter. MMGuardian says its web filter works in incognito mode. Skie blocks incognito altogether, forces SafeSearch and YouTube restricted mode in Chrome, locks a filtering DNS so it applies on Wi-Fi and mobile data, and always blocks more than 50 other browsers, VPN apps and proxy apps.

On location, MMGuardian emphasises GPS that a child cannot switch off. Skie has live location with a trail, geofence alerts, a go-to directions button and an SOS button that calls the emergency number. I could not confirm geofences or an SOS button on the MMGuardian pages I read.

The biggest difference is message monitoring. MMGuardian shows messages, including deleted ones, and flags risky content. Skie does not read private messages, call logs or record audio or video, and has no hidden mode. Which approach is right depends on your family's view of privacy and trust.

Tamper resistance and bypass

On the MMGuardian Phone the maker says the controls are installed at system level, so the child cannot uninstall them, use safe mode, factory reset or set up a VPN, and incognito does not defeat the filter. Independent coverage notes that the app-only version is weaker and can be defeated by a factory reset, with the parent getting an alert if the app stops running.

Skie uses Android device-owner mode. Factory reset from Settings is blocked, safe mode is blocked, developer options and adb are blocked, and Skie cannot be uninstalled or force-stopped. If a phone is wiped from the recovery menu, Android's Factory Reset Protection asks for the Skie organisation's Google sign-in, which only Skie holds, so a reset device is of no use to whoever took it. If anything ever did get through, the parent is alerted immediately, down to the exact device.

In other words, Skie's lock sits at the same level as the MMGuardian Phone's, but on a device you already own, not only on the maker's hardware.

Phones and tablets

MMGuardian covers tablets through its app, including a cheaper Android tablet plan and iPad support, but not through a branded tablet. Skie manages any Android 12 or newer phone or tablet with the same device-owner lock, and a Wi-Fi-only tablet works for most features. If your child uses an iPhone or iPad, Skie does not support iOS and MMGuardian's app does.

Who should pick MMGuardian

Pick MMGuardian if you want to see your child's messages and be alerted to risky content, if you need per-app time limits and usage reports now, or if you are in the US and want a Samsung with the controls already inside. It also suits families with an iPhone or iPad in the house, since the app covers Apple devices.

Who should pick Skie

Pick Skie if you want strong device-level protection but do not want to read your child's messages, if the phone or tablet is already owned, or if you are outside the US. It suits families who want geofences, an SOS button, bedtime and study schedules, and lost mode with a police-report evidence pack. It is the same company that serves schools and hostels, so the lock model is proven in institutions.

Skie sells no phones and includes no mobile plan. Per-app time limits, screen time reports and message monitoring are not offered today, and message reading will not be.

How setup with Skie works

The device is freshly set up or reset once and any Google account is removed, because Android only allows device-owner management on a device that has not been set up. The parent provisions it with the Skie Provision app from Google Play or a computer and cable, and a new model passes a one-time model review. Then the parent signs in to the browser dashboard, chooses apps, adds a schedule and a geofence. The phone shows that it is managed.

Verdict

MMGuardian is a capable choice for US families who want message monitoring, per-app limits and a Samsung with the controls built in. Skie is the better fit when you want the same level of device lock on a phone or tablet you already own, any Android 12 or newer brand, with geofences and SOS, and without reading private messages. Skie has no per-app time limits yet and includes no phone or mobile plan.
