市面上售价 59 美元的 Brick 装置透过物理 NFC 感应帮助使用者摆脱手机干扰，但使用者其实不需要花大钱购买这类硬体。市售的一般空白 NFC 标签仅需约一美元，甚至只要利用印表机列印出 QR Code 或扫描现成条码，就能搭配免费软体达到相同的物理阻隔效果。

针对 iOS 系统，开源且免费的应用程式 Foqos 提供了高度精致的使用体验。使用者可以透过设定 NFC 标签、列印 QR Code 或扫描家中物品的条码来启动专注设定档，封锁特定应用程式；此外，该程式还能在专注模式下防止使用者删除 App 来规避限制，并具备严格的本机隐私保护设计。

在 Android 平台上，Switchly 则是功能相当丰富的免费选择，支援透过 NFC、QR Code 或排程来封锁特定应用程式及网址，甚至能实验性地封锁部分特定 App 的内部功能（如 Instagram 短影音）。若追求更简洁的体验，仅支援 NFC 的 Lock 应用程式亦是另一个值得尝试的优质工具。

The $59 Brick device uses physical NFC taps to help users detach from screen distractions, but buying expensive dedicated hardware is unnecessary. Blank NFC tags can be purchased for around a dollar, and simple printed QR codes or household barcodes can achieve the same physical friction when paired with free software.

For iOS users, Foqos is a polished, free, and open-source application that lets individuals block distracting apps by tapping NFC tags, scanning printed QR codes, or scanning household product barcodes. It enhances self-control by preventing users from uninstalling apps during active sessions and keeps all personal data strictly local on the device.

On Android, Switchly serves as a feature-rich alternative that supports blocking apps and URLs via NFC, QR codes, or custom schedules, even offering experimental options to restrict specific in-app features like Instagram Reels. For those who prefer a more streamlined experience focused solely on NFC tags, an app called Lock is another solid option.
