Choose a Focus Profile, set a duration, and see whether each device is protected—without a vague all-green status hiding a problem. FOCUS YOUR WAY • Start 25, 50, or 90-minute sessions, or choose a custom duration. • Build Profiles for Deep Work, Study, Reading, and your own routines. • Block selected apps and websites on iPhone and iPad with Apple's Screen Time controls. • Use the free Mac companion to protect supported apps and websites. • Keep a session going with local rain, café, train, forest, wave, and other procedural sounds. ONE SESSION, HONEST STATUS Private iCloud sync carries your active session, Profiles, schedules, history, and verified Pro status between devices. OneFocus shows iPhone Protected, Mac Protected, Waiting, Needs Permission, or Offline separately, so you know what is actually happening. Existing local sessions and history remain useful offline.
