How it works
Start the class
Start the session from any browser. New students join once with your class code.
Students tap in
Each student holds their iPhone to your Bali block. Their apps lock on the spot, even without Wi-Fi.
Apps open at the bell
Everything comes back on its own when class ends, and you get a recap of the class.
For teachers
- A live grid of who's focused and who's unlocked
- Add 5 or 10 minutes, or end class early
- Questions and slides on every phone
- A recap after the bell, every unlock included
For students
- Calls, FaceTime, Messages and Emergency SOS keep working
- Emergency Unlock any time: hold for one second
- Saying why is optional
- Apps open at the bell, even with Bali closed
Bali never sees a student's screen, messages, location or apps.
Teachers see what they need to run the class: who's focused, when each student taps in or unlocks, and the reason if they share one. A student's answers to questions count only toward the class's totals.

Questions
What happens in an emergency?
Students can unlock any time by holding for one second, and their apps open right away. Calls, FaceTime, Messages and Emergency SOS never lock. Every unlock shows on your grid and in the recap.
Does it work without Wi-Fi?
Yes. A tap locks the apps right away with no signal, and the phone tells your grid once it's back online.
Can a student turn Bali off?
They can switch off Bali's Screen Time access in Settings. If they do, your grid shows Screen Time off for them.
Is there an Android version?
