The answer is less apps and device time. Even having an app to help with 'human downgrading' takes up brainspace and a lingering attachment to the screen and devices. Though I suppose since screentime/devices aren't going away any time soon might as well try to mitigate it a bit.
I spent some time on their website and found humanetech's strategy to be well thought out. They aren't promoting an app, but rather a "combination of thought leadership, pressure, and inspiration to create market demand and momentum for products and services based on Humane Technology principles".
Sitting back and doing nothing or promoting just using less technology doesn't really address the runaway train that many feel they are on. If they are able to actually effect any of the 1000 or so people who are positioned to make changes to these products, then it may make a dent.
In particular I think the Freedom app is pretty unique in that you can setup web and app blocklists and it is synced between devices when you have it setup on all of them. So you can set a focus time of 4 hours for example and the apps and sites (and entire categories of sites if you wish) you specified will be blocked on all devices, Windows, Mac, iOS, Android. Surely there are plenty of apps that do similar things but I think the integration of multiple devices is pretty killer as you don't need to manage each one.
The InboxWhenReady and Distraction-Free YouTube extensions I think are really useful too.
