I have occasionally wanted to trigger location-specific behavior on my kid's devices, like turning the wifi off when in their bedroom. This feels broadly in the category to me.

Doesn't that mean you'd also need to somehow disable mobile data, and possibly calls as well if you don't want them phoning their friends late at night?

Might be easier to insist that phones charge overnight in some parentally-observable central area... Though I suppose they might use them for alarm clocks.

I'm curious why the NFC tags are required at all? Can't you switch profiles on your phone without scanning an NFC tag already? Couldn't your app allow profile switching without requiring any NFC tags? It's not clear to me what the NFC tags add to this experience.

For a while I stuck NFC tags on the MagSafe charger/stands in various places (at my desk, by my bed, etc.) to swifch profiles (which can be done just using shortcuts, as others have mentioned).

It worked pretty nicely but in the end I found it not to be all that useful and I’d be frustrated by the profile change as often as I was happy with it.

By the way, you can trigger iOS shortcuts with NFC tags, so in principle you can trigger any functionality exposed as a Shortcut action. However, NFC recognition doesn’t always work as smoothly as one would hope.

To expand here, when using NFC to trigger an iOS shortcut, there's nothing actually written to the NFC. Instead, shortcuts responds when that NFC is present. So you can actually write something like a URL to the chip and have it act simultaneously.

You can even use an airtag because it sees it as an NFC as well.

not just occasionally but often, in our experience with multiple phones and iPads. I have 2 kids with devices and have found Screen Time completely useless. It is the right idea in theory but in practice it's broken (I'm guessing no Apple higher ups have young kids that they've tried to use this with.) Also, besides the resets (and by reset I mean not just time restrictions but content restrictions too), my kid can j…

There are many YouTube videos for teens on how to bypass ScreenTime. It’s a mess that Apple needs to clean up quickly

For this reason a configuration profile [1] is the only fool proof method. However, I have only used them to deploy permanent content restrictions. I don't know of a way to enable or disable restrictions based on the time of day or a certain duration.

How is that different from the parent holding the code?

One scenario I can think of: When there's an occasion where you want to give them unlimited time, but you don't want to disclose the code and then later have to reset it to something new. Or you want to delegate permission to a babysitter. You just give them the doohickey and ask for it back later. (Cloning the NFC tag is a much harder job that remembering a PIN.)

Not unlike using a TPM to prevent users from copying copyrighted content while still allowing controlled access.

That seems like a rather unfair comparison, tarring "parent won't let child watch movies after bedtime" with the same brush as "international megacorp sabotages hardware you own in profit-seeking paranoia."

Heck, in many jurisdiction the device is owned by the parents anyway, not the kid.

Device could be a tablet without cellular.

Anyway, my son has a phone (hand down from me 5 years ago) without cellular.

The app does allow manually switching of profiles, without NFC tags, but it wasn't clear until I installed the app.

How do I do this?
