| Mobile plan or carrier included | No. The family keeps its own carrier. | No. Skie has no SIM or mobile plan, so the family keeps its own carrier. Wi-Fi-only tablets work for most features. |
| Level of control on Android | App level on the child's device. Not publicly documented as device owner mode on the pages we reviewed. | Device owner. Android itself enforces the rules, with each protection a separate policy switch. |
| Can the child remove it or reset around it | The MMGuardian Phone is described as unable to be factory reset or have protections disabled; the app's own removal behaviour is Not publicly documented. | Built to be tamper-proof. Factory reset from Settings, safe mode, developer options, adding users and uninstalling Skie are blocked by default, and Factory Reset Protection ties a wiped device to the Skie organisation's Google sign-in. If anything did get through, the parent is alerted immediately, down to the exact device. |
| App control | App blocking and app time limits. | Parent chooses which apps work. An app installed later that is not allowed is removed silently. The Play Store can be hidden. Blocking beats allowing. Apps are hidden or suspended, not deleted. |

Mark found to return to normal. Remote erase is not available yet. |
| Replace or reassign a device | Not publicly documented | Yes. Replace a device and keep the child, group and history; the old seat is freed. A reset device is recognised by IMEI or serial and does not take a second seat. |
| Alerts and who gets them | AI-based alerts for predators, bullying, drugs, sexting and suicidal thoughts. | A breach centre shows tamper and compliance events, and a missing check-in counts as a breach. Email alerts and push notification of alerts to parents are not available yet. |

What MMGuardian (the app) is and how it works
The MMGuardian app installs on a child's existing phone and lists full access to messages, apps and browsing, location, app blocking, screen time and app time limits, AI alerts and age-based controls. The company also sells a separate Samsung phone with the controls built in; that is a different product from this page's subject.
What it costs
The app starts from $4.99 a month with a 14-day trial, per its home page. The phone costs more. Skie has no hardware cost and pricing is on request.
Controls compared
The main difference is messages. MMGuardian gives parents full access; Skie never reads them. On control, Skie enforces as device owner with a locked filter, SOS and lost mode. Skie does not offer daily screen time limits, per-app time limits or usage reports yet. What it does today is schedules: study and bedtime windows that switch the allowed apps on their own, plus remote lock. The team is working on usage limits, with no dates. If minute-by-minute limits and reports are the main thing you want, that is a real reason to choose a tool that has them.
Removal and bypass: app level versus device owner
Parental control tools work at two different levels, and the difference matters when a child is determined. An app on the child's profile relies on permissions the device grants it, such as device administrator, accessibility or usage access, and Android lets the person holding the device review or change some of those. A device owner is set when the phone is first configured, so Android itself treats it as the authority and Settings gives the user no way to remove it. That is a general difference between the two models, not a verdict on any one product, and each maker documents its own protections. Skie runs as the device owner and is built to be tamper-proof. Factory reset from Settings, safe mode, developer options, adding users and uninstalling Skie are blocked by default, and with Factory Reset Protection a wiped device 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 admin or parent is alerted immediately, down to the exact device. The trade-off is setup: the phone or tablet must be freshly set up or reset once, with any Google account removed first.
Who should pick MMGuardian (the app) and who should pick Skie
Choose MMGuardian for full visibility and time limits. Choose Skie for control without message reading.
How setup with Skie works
Setting up Skie for a family uses the parent dashboard in a browser and the Skie Provision app from Google Play, or a computer and a cable. Because Android only allows device owner management on a device that has not been set up, the phone or tablet must be new or reset once, and any Google account removed first. You pair over Wi-Fi, follow the guided steps, and watch live progress with a clear reason if something fails. A new device model goes through a one-time model review during setup. After that you pick the apps that work, hide the Play Store if you want, turn on adult-site blocking, add study and bedtime windows and set geofences. The phone shows that it is managed, with no hidden mode. Skie does not include a mobile plan, so the family keeps its own carrier. Pricing is on request, and it is one device per child.
