## What is BigBro?

BigBro blocks the apps and websites you choose while you focus, using Apple's Screen Time.

BLOCK APPS AND WEBSITES
• Pick apps, app categories and websites to block during a focus session.
• A built-in list of entertainment sites, plus your own.
• Adult websites can stay blocked all the time, not only during focus.
• Save focus types with their own block lists and lengths.

THREE DIFFICULTY LEVELS
• Gentle: end a session whenever you want. Your supervisor is notified.
• Hardcore: ending early means holding through a three-door ritual.
• Supervisor lock: ending early needs your supervisor's approval.

SUPERVISORS
• Invite someone by email. They don't need the app.
• They get an email when you end a session early, ask to unlock, or stop checking in for a long time.

STUDY ROOMS
• Take a seat in a 3D classroom and focus with other people on a shared timer.
• Rooms in cities around the world, or a private room with a code for friends.
• Reactions, and chat during breaks. Messages can be reported and people blocked.

STREAKS AND PROGRESS
• Each finished session counts toward your streak, with milestones from 3 days to a year.
• Lock Screen and Dynamic Island show time left. Apple Watch shows your streak and the current session.

Also available for Mac at bigbro.libreadam.com. The two stay in sync when you sign in.

Requires iOS 16 or later and Screen Time permission.
