Thirty seconds is the whole design constraint
A ten-minute meditation is a fine thing and a terrible interruption. If the alternative to opening Instagram costs more than opening Instagram, nobody picks it — so the reset is built to be over before the urge is.
Four kinds, all roughly half a minute: a guided breath cycle, a single affirmation, a short meditation, or a visualisation of something you are working toward.
You pick what a reset means to you
Breathing suits the moments when the reach is anxious. Affirmations suit the ones where it is avoidant. Visualisation pulls attention forward to something you actually want. Meditation is there when you have a minute rather than a moment.
You can set a default and change it whenever the default stops fitting.
The reset is the product, the blocking is the trigger
This is the part that separates Champ from a plain app blocker. Blocking creates an empty gap; an empty gap gets filled by the next-nearest app. The reset gives the gap something to be.
Champ is free on iPhone — three shielded apps, thirty-second resets, no card needed.

Mindful Pause puts a shield in front of the apps you overuse. Open one and Champ intercepts it, offers a 30-second reset, and only then lets you through — or not.
Your garden
Every reset you complete waters your garden. It is a visible record of choices you made instead of scrolls you took, which turns out to be far more motivating than a screen-time bar chart.
