Kenneth Schlenker worked on product and data at Google, contributing to Google Maps, YouTube and Google Ads. He now runs Opal, an app that helps people manage screen time and stay focused.

His earlier work was about keeping people engaged on their devices. At the time, that was the goal. But he’s since seen the downside. These systems are designed to keep people on their phones for longer, whether they enjoy it or not. On average, we spend around 5 hours a day on our phones. People are finding it harder to stay present in real-life interactions and to focus on one task. The patterns are starting to look a lot like addiction. He sees this as a wider issue, not just a matter of willpower. Opal is his response to that. It adds small barriers to make phone use more intentional and easier to control.

In this episode, you will discover:

Modern apps are engineered as "engagement factories" that monetise your time by selling it to advertisers.
Digital addiction isn't a failure of willpower; it’s the result of systems designed specifically to defeat human self-discipline.
Excessive screen time is a primary driver of the current global mental health and productivity crisis.
Using tools to create "friction"—like breathwork or puzzles before opening an app—helps break compulsive cycles and reclaim focus.
Long-term change comes from reframing your identity rather than relying on short-term diets or restrictions.

This episode offers Health Coaches a powerful framework for helping clients navigate the "attention economy" by shifting the focus from guilt to structural change. By understanding that these digital systems are specifically engineered to override self-discipline, you can better support your clients in implementing "intentional friction" to protect their mental wellbeing and productivity. This shift from relying on willpower to redefining one's identity allows clients to move beyond passive consumption and rediscover the value of presence, rest, and focused living.
