Spark vs Google Family Link
These are different products, and the honest comparison starts there. Family Link is free supervision: a parent's account controls a child's Android phone at the system level, with app approval, limits, content filtering and location. Spark is a self-control tool — it has no dashboard, no reports and nothing a parent can watch, because it is designed for the person holding the phone to use on themselves. If you want to supervise a child's device, use Family Link; it does that better than anything we sell. If you want a teenager to build a habit they own, or you want this for yourself, supervision is the wrong shape and a key is the right one.

How Google Family Link works
Google Family Link is Google's free parental-controls service, in which a parent supervises a child's Google Account and the Android or ChromeOS device signed into it.
Account-level supervision enforced by the operating system rather than by an app that can be uninstalled: a parent approves app installs, sets screen-time and per-app limits, applies content filters and sees device location. Google notes that system apps cannot have app limits placed on them.
Platforms
Supervised device: Android 7.0 and later, and ChromeOS 71 and later. The parent app runs on Android 7.0+ or iPhone on iOS 16+. An iPhone cannot be supervised — Google says children signed into iOS, web browsers or other unsupervised devices “can only be partially supervised”.
Pricing
Free. There are no in-app purchases, and creating a child's Google Account costs nothing.
How hard it is to get around
Harder than any app-level blocker, because enforcement is in the account and the OS. The documented gaps are real, though: signing in on an iPhone or a plain browser leaves only partial supervision; system apps cannot take app limits; and approval is not required for updates to apps already approved, or for apps shared through Family Library. A teenager aged 13 or over can also ask to end supervision — the parent must approve, and both are notified, so it is a visible exit rather than a silent one.
The difference that matters
Supervision, or a habit the teenager owns
Family Link's design assumes the right answer is a second person with authority: a parent decides, the OS enforces, the child complies. For a ten-year-old's first phone, that is exactly right, and no amount of hardware improves on it.
It ages badly, though, and every parent of a fifteen-year-old learns why. Supervision creates an adversary — the effort moves to the second phone, the friend's device, the browser that is not supervised — and it teaches the teenager that phone limits are something done to them rather than something they do. The exit is even built in: at 13 they can ask to end it.
Spark is the other shape on purpose. There is no dashboard, no activity report and nothing sent to a parent, because the teenager sets their own modes and fetches their own key. It is weaker as enforcement and better as practice — which is the right trade once the goal has shifted from controlling a child to sending a young adult off to a hostel with a habit that holds without you.
To be fair
When Google Family Link is the better choice
Being the only tool here where the controller is a second person with genuine authority, for free, enforced by Android itself. Nothing else in this comparison set combines app approval, content filtering, screen-time limits and location, and nothing else survives the supervised person simply uninstalling it.
Choose Google Family Link if
- You are a parent setting up a younger child's first Android phone. This is the right tool and it costs nothing.
- You need app approval, content filtering and location in one place.
- The device is a school Chromebook on a supervised account.
- You need limits that hold even when the child is unwilling — supervision does that, a key deliberately does not.
- You want something available and free today.
Documented limitations
- An iPhone cannot be fully supervised; only some settings carry over.
- System apps cannot have app limits placed on them.
- Approval is not needed for updates to already-approved apps, or for apps shared through Family Library.
- A teen aged 13 or over can request to end supervision, with the parent notified and approving.
- Google's own FAQ concedes its content filters “are not perfect”.
- It is supervision, so it does nothing for an adult trying to manage their own phone.

Questions
Google Family Link, answered
What is the best alternative to Family Link?
It depends what you want from it. For supervising a young child's Android phone, nothing here beats Family Link and it is free. For a teenager or an adult managing their own phone, a self-control tool is the right shape — Spark, or a software blocker like AppBlock or Stay Focused.
Can Family Link control an iPhone?
Not fully. Google says children signed into iOS, browsers or other unsupervised devices can only be partially supervised: some YouTube and Search settings carry over, but app management, Chrome filtering and screen-time limits do not. For an iPhone, Apple's own Screen Time with a parent-held passcode is the closer equivalent.
Can a teenager turn off Family Link?
A teen aged 13 or over can request to stop supervision. The parent has to approve it and both are notified, so it cannot be done silently — but it exists, and at that age the conversation tends to matter more than the control.
Is Spark parental-control software?
No, deliberately. There is no dashboard, no activity report and nothing shared with a parent. It locks apps the person chooses and puts the unlock on a key they fetch themselves — which is why it works for a teenager who has agreed to it and not for a child who has not.

Locking is one tap. Unlocking costs you a walk.
No subscription. Buy a Spark once and sign in to pair it; after that, locking is one tap, even offline. Unlocking means fetching the key and holding your phone against it — which turns a bad moment into a walk.
