This $9 key physically locks your most addictive apps

Autonomous Key is a $9 NFC device that physically locks distracting apps on smartphones by requiring a scan to unlock them for up to 60 minutes, aiming to reduce screen time by adding physical effort to access. It works with Android and iOS, offers AI insights on usage habits, and supports multiple phones without subscriptions. Some users report occasional scanning issues, and losing the key could pose access challenges.
