How it works

A simple routine that creates fast, visible compliance checks for teachers and administrators.

How to manage phone usage in three steps
Phone goes into pouch on entry → pouch stays locked in the phone-free space → unlock at an approved base when allowed.

Phone goes into pouch on entry

At the start of the phone-free session

When students enter a phone-free space (for example, a classroom or assembly hall), they place their phones into their personal pouches.

  • Each student has a clearly labelled pouch.
  • Teachers do a quick visual check rather than handling phones.
  • This becomes part of the normal start-of-lesson or start-of-day routine.

Pouch stays locked during lesson

Phones are present, but not accessible

While students are in the phone-free space, the pouch remains locked. They keep the pouch with them, but cannot access their phones.

  • No keys to manage – the lock is built into the pouch.
  • The clip design avoids needles or sharp points, making it more child-friendly than some pin-and-lock solutions.
  • Phones are physically present but not available, reducing under-the-table use and distraction.

Unlock at a base when allowed

Only at approved times and locations

When students are allowed to use their phones (for example, at dismissal or at designated times), they step outside the phone-free zone and tap their pouch on an unlocking base.

  • Unlocking bases are installed at locations chosen by the school.
  • Students unlock only at approved times, supporting consistent expectations.
  • The same routine applies across classes, reducing confusion and negotiation.
