There are plenty of apps and organizational systems that will help you remember future tasks and reduce distractions. For example, Focus blocks distractions and schedules your breaks and Freedom will block distractions on all of your devices at once. - Source: dev.to / 10 months ago

Just https://heyfocus.com which I must have installed through Setapp, as I don't remember paying for it. It has a scripting capability so in theory I might be able to do something to prevent it from triggering when I'm active in a form. - Source: Hacker News / about 1 year ago

There is a paid app called Our Pact that we used when my kids were younger. We don't use that anymore but did until they hit about 15 or so. It's really good; works on both android and ios. My kids have an Android phone (our old Samsungs) with limited data and unlimited calling/text. Source: about 2 years ago
