What it is

This is a clear-base container with a timer built into the lid. You set a duration, close the lid, and the box stays locked until the timer runs out. The point is not force; it is friction. Reaching for a phone during homework, dinner, or deep work is usually automatic rather than deliberate, and a box that cannot be opened for the next 45 minutes converts that automatic reach into a conscious choice. The clear base means you can still see the device, which some people prefer for reassurance, while the access port allows a charging cable to run inside.

Why HOS selected it

It is the most direct physical answer to the most common request we hear: make the phone genuinely harder to pick up for a defined period.

Key features

  • Timer-controlled lid that stays closed for a chosen duration
  • Clear base so the contents remain visible
  • Access port for a charging cable

Who it is for

Individuals, students, and families who want a simple physical commitment device for defined blocks of time.

What it will not do

It is a friction device, not a security safe. A determined person can break or bypass a plastic container, and it does not block calls or notifications reaching the phone inside.

Buying considerations

  • Measure your phone with a case on before choosing a size
  • Decide whether you need to hear emergency calls during a locked period
  • Consider who else in the household needs access
