GoKawiilFree apps Foqos and others replicate $59 Brick's NFC-based phone-blocking feature
The Brick device blocks distracting apps via an NFC chip that users tap to start and stop blocking sessions, but this functionality can be replicated using blank NFC tags costing about a dollar or printed QR codes. Free apps such as Foqos for iOS, built by developer Ali Waseem, let users configure app-blocking profiles tied to NFC tags, QR codes, barcodes, or daily schedules, and can prevent users from disabling the block by deleting the app.
