The best distraction blocker in the batch: free, open source, works via NFC or QR code, and physically cuts off your phone with a real-world action. Occasionally a profile deactivates on its own, and the QR scanner breaks on some devices.
評価点：Physically scanning an NFC tag to lock the phone creates a far stronger ritual than any in-app button.
不満点：The block sometimes disables itself, making the phone accessible without scanning.
向いている人：People with serious phone addiction who need a real physical barrier
A physical dongle, an NFC fob, as the unlock mechanism creates a real barrier against impulsively picking up the phone, and it honestly works where purely software solutions give in. The decision to remove the timed session feature without a replacement frustrated loyal users and reduced everyday flexibility.
評価点：The physical ritual of touching the fob breaks the automatic reflex far better than an on-screen warning.
不満点：Quick session-by-duration launch was removed, leaving only scheduling, which does not work for unpredictable days.
向いている人：People with serious phone addiction who are willing to carry a fob
One of the few blockers with cross-device sync and a hard mode that actually works. The VPN layer can slow down the internet or conflict with other apps, and iOS settings allow the block to be bypassed.
評価点：The hard mode with one unlock per week removes the escape hatch for weak moments.
不満点：The VPN layer periodically slows down apps you actually need and conflicts with other services.
向いている人：Adults with serious phone addiction who need a reliable multi-device barrier
A minimalist mindfulness tool: before opening a blocked app you take a deep breath or do a short exercise, which genuinely breaks autopilot and reduces social media use. The weak point is that the free tier blocks only one app, making it nearly useless when you need to limit several social networks.
評価点：A pause before Instagram breaks the conditioned reflex better than a hard block. Several reviews describe real habit change within weeks.
不満点：Hard blocking is easy to bypass even in the paid version, and one app on the free tier is far too few.
向いている人：People who want to mindfully cut back on social media rather than block it by force
The blocker works harder than iOS Screen Time and genuinely cuts social media use by a large factor. The absence of a scheduled block by time of day limits flexibility.
評価点：The five-minute forced limit after time runs out is strict enough to break the habit loop.
不満点：No way to automatically enable a block on a schedule, for example overnight.
向いている人：Adults who find iOS Screen Time too easy to bypass and need a real barrier
