Vow

Vow is a native macOS productivity app that turns off all network connections (Wi-Fi, Ethernet, iPhone hotspot) and keeps them off until your timer ends.

Designed for deep work, coding, and writing without online distractions. Localhost, local files, and Bluetooth stay completely functional. No accounts, no subscriptions, and zero bypasses — quitting the app or restarting your Mac will not restore internet until time runs out.
