I've seen hacks like this, and have used them myself too.<p>However, suggesting this to friends (and myself) I see two things that undermines the process, that the metric used here does not catch.<p>1. Usage over a long time span is usually not a "decline" but a "wave-like" pattern. aka rebound, or substitution. You remove one distracting app, stay productive for a week or a month, then rebound to same or <i>another</i> app. Repeat process.<p>2. Substitution through other media. As this one said, "use laptop/PC for mindfully using Social Media", this sounds really good, but in practise usually given time, returns to mindless browsing. That's how we work, our brain constantly tries to push things we have to do mindfully to an automated "mindless" process. The tricky thing with this is that, we usually don't consider the process "mindless" until long after it have become an mindless process.<p>It would be interesting, if you can observe your usage pattern over longer time-span. Not just Smartphone but also your PC/Laptop and observe if you <i>truly</i> have reduced your "distraction" time.
