Distraction-blocking apps do not require buying dedicated hardware such as the Brick, because inexpensive NFC chips, QR codes and even existing barcodes can create the same physical barrier. The approach makes accessing distracting apps less convenient, helping users resist impulsive scrolling and focus on other activities.

For iPhone, the free open-source app Foqos supports NFC tags, QR codes, barcodes, schedules, app restrictions and limited breaks, while keeping data on the device. Android users can try Switchly, which blocks apps, websites and selected in-app features, though setup is more complicated and performance varies by phone; its free tier is sufficient for most users. Another option, Lock, is more polished but works only with NFC chips.
