Classroom phone management
More class.Less scroll.
Keep distracting apps out of class—and useful tools in it. Teachers choose what’s allowed. Students keep their phones. Normal access returns when class ends.

Phones stay with students
App access stays with teachers
A clear start. A clear finish.
A simpler class routine
Set up once. Get on with teaching.
No collecting phones. No handing them back. Just a class routine that everyone understands.
02 / START CLASS
Students tap to enter.
Start now or use your recurring schedule. Students enter the period, and their phones follow your class rules.
03 / WRAP UP
Class ends. Apps return.
Each phone stores the class ending time locally. Restrictions are designed to expire even if its connection drops.
Built around the lesson
Sometimes the phone
is part of the plan.
A class quiz. A research activity. A photo of a lab experiment. Allow the apps you need, then stop allowing them when you’re done.
- Choose one app or several for an activity.
- No new class, new code, or timer required.
- Return to your class rules with one control.
A little flexibility goes a long way
Time for a class quiz?
Allow the browser for a web-based Kahoot.
Capture the experiment.
Make Camera available for the activity.
Back to the lesson.
Stop allowing. Your class rules return.
Browser access isn’t limited to one website. iPhones may need Apple’s one-time app selection before a newly allowed app is available.
Know the class status. Not their business.
Classroom management.
Personal boundaries.
Teachers can check participation and reported protection status without reading what’s on a student’s phone.
Read the privacy noticeNo message, screen, or location monitoring.Timbrae does not collect message content, browsing history, screen recordings, or location.
Essential access stays part of the plan.Phone calls, emergency access, and separate health-access options are built into the class flow.
A status check. Not an accusation.A missing update can mean a connection problem. Teachers can ask students to verify, then follow up.
Good questions
The short answers.
Have a classroom situation in mind? Let’s talk through how Timbrae could fit.
Get in touchDo students have to hand over their phones?
No. Timbrae runs on the student’s phone. They keep the device while apps that are not allowed for the class are restricted. There are no pouches, collection boxes, or additional hardware to buy.
Does it work on iPhone and Android?
There are test builds for iPhone with iOS 17 or later and Android 8 or later. Setup and device permissions differ. On iPhone, Apple’s app picker may be needed for allowed apps. Ask for a walkthrough before planning a rollout.
Can I allow apps just for an activity?
Yes. Choose apps such as Browser and Camera, select Allow apps, and select Stop allowing when you are done. You don’t need to choose a number of minutes or create another class. Connected phones receive the change; an iPhone may need to open Timbrae or finish app setup first.
What happens if a phone loses internet?
The scheduled class ending time is stored on the phone, so an outage should not extend the class restrictions. Changes made during class, including ending early or changing allowed apps, need to reach the phone. A missing update is not proof of tampering.
What about emergencies and medical needs?
Phone and emergency access remain available, and Timbrae includes separate health-access and teacher-approved temporary-access options. Individual needs should be reviewed before anyone participates. A school must keep its own emergency and accommodation procedures.
Can our school use Timbrae now?
Timbrae is in early alpha, with testing currently limited to consenting adults. We’re welcoming conversations with teachers, professors, and school leaders. K–12 use requires further product readiness and legal review; this is not a public school rollout or a claim of certified compliance.
