I recommend this one for Android: https://github.com/markusfisch/ScreenTime

It doesn't limit apps, it just displays your screen time in a permanent notification and allows you to view and export past statistics.

I've found that to be very effective. From a systems perspective, it amounts to adding a new feedback loop, similar to this leverage point described by Donella Meadows[1]:

There was this subdivision of identical houses, the story goes, except that for some reason the electric meter in some of the houses was installed in the basement and in others it was installed in the front hall, where the residents could see it constantly, going round faster or slower as they used more or less electricity. With no other change, with identical prices, electricity consumption was 30 percent lower in the houses where the meter was in the front hall.

We systems-heads love that story because it’s an example of a high leverage point in the information structure of the system. It’s not a parameter adjustment, not a strengthening or weakening of an existing loop. It’s a NEW LOOP, delivering feedback to a place where it wasn’t going before.

These don't work for me. My brain knows I'm deceiving it, so it doesn't respond to this kind of stimulation.

Does it do the fancy NAT-traversal Tailscale does?

“When you invent the ship, you also invent the shipwreck; when you invent the plane you also invent the plane crash; and when you invent electricity, you invent electrocution... Every technology carries its own negativity, which is invented at the same time as technical progress.”
