TL;DR
A person struggling with phone addiction used a magnetic lock device to limit app access, resulting in more focus and calmer brain activity. This practical hack offers a promising approach for others seeking to reduce screen time.
A person who was spending about eight hours a week on their phone has reported that using a magnetic lock device significantly reduced their screen time and improved focus.
The individual, who tracked their phone usage via Apple’s Screen Time app, found that limiting access to social media apps like Reddit and Instagram helped them regain time and mental clarity. They used a device called Brick, a magnetic square that attaches to a metal surface, which physically blocks access to selected apps unless the user actively unlocks them with a second touch.
This method introduces friction, making it less convenient to mindlessly open apps, and has reportedly led to a calmer, more focused state of mind. The user still maintains access to essential apps like WhatsApp and Gmail for work and communication but has restricted social media during most of the day and at bedtime. The device costs around £54, but the individual considers it a worthwhile investment for mental well-being and productivity.
Impact of Physical Barriers on Phone Use
This personal account highlights a practical, low-cost intervention that can help individuals curb excessive screen time. Using physical barriers like the magnetic lock device introduces a tangible obstacle to compulsive app checking, which may be more effective than solely relying on digital limits or self-control. Such approaches could be valuable for others seeking to improve focus, mental health, and overall well-being in an increasingly digital world.

Growing Awareness of Digital Addiction and Self-Help Strategies
Recent research indicates widespread concern about the impact of excessive phone use. Experts like Prof Marcantonio Spada have emphasized that many people outsource their cognitive functions to devices, which can lead to reduced real-world engagement and emotional numbness. Psychotherapists also note that habits formed around social media can be hard to break, but initial discomfort often gives way to positive reinforcement.
Various techniques, including not keeping phones close or using physical locks, are gaining popularity as practical solutions. The personal story aligns with broader trends of individuals seeking tangible ways to regain control over their digital habits.

Limitations and Long-term Effectiveness of the Hack
It is not yet clear how sustainable or scalable this method is for different users or over extended periods. The long-term psychological effects and whether users might find workarounds remain uncertain. Further research and larger studies are needed to confirm the efficacy of physical barriers like the magnetic lock device in reducing overall screen time.
Further Research and Broader Adoption of Physical Barriers
Researchers and mental health professionals may investigate the long-term impacts of physical app-locking devices. Meanwhile, individuals interested in reducing screen time might experiment with similar tools. Tech companies could also develop integrated solutions that combine digital limits with physical barriers to enhance effectiveness.
