The one thing I’ve found that works for me on my phone is the OneSec app. It hooks into shortcuts (for apps) and a Safari extension (for websites) to prompt you with a small task to do (eg a 20sec breathing exercise) before you access the softblocked content. The time delay + task is enough for me to remind myself that this isn’t what I want to be doing. And in the instances where I actually do consciously want to visit XYZ platform, I can just do the exercise and be granted access.

The only downside is that the Safari extension is granted full access to my web browsing in order to facilitate the website blocking. They say they don’t capture any data and at this point do trust them (you may feel differently). For blocking apps, no private data sharing is required.
