Tether vs Duna's AI Scanner

You open your phone for "just a second" and lose 45 minutes to scrolling. Tether is an app blocker built to break that loop with real friction. Block apps, websites, and categories, then choose how hard it should be to stop: tap out, scan an NFC tag, scan a QR code, or get approval from someone you trust. Focus modes for real life - Indefinite sessions when you just need to stay locked in - Countdown sessions for deep work, study, and sprints - Pomodoro sessions with built-in breaks - Scheduled sessions for work hours, bedtimes, and daily routines Why Tether works - Create reusable blocklists for work, study, sleep, and weekends - Use Allow Mode to block everything except what you need - Turn on Strict Mode to prevent easy loopholes mid-session - Keep emergency overrides for genuine exceptions - See your session with Live Activity and Dynamic Island - Sync across devices so your rules stay consistent Tether is for people who want less screen time, stronger phone habits, and a system that's harder to cheat. Make distractions harder to reach, make quitting harder to justify, and make focus easier to keep. Terms of Use: https://www.tetherto.me/terms Privacy Policy: https://www.tetherto.me/privacy
