Android porn reduction app · 7-day free trial

Keep the blocker.
Watch less porn.

Cairn interrupts configured porn sites with camera-counted exercise. Finish the set, then decide whether to leave or continue.

How Cairn works

One interruption.
Three clear steps.

Cairn puts a physical pause before access.

01

Cairn catches it

Cairn detects a configured site and interrupts it before the page becomes the default next move.
02

You move

Open the camera and complete the exercise. Cairn counts each rep with on-device pose detection.
03

You decide

Cairn does not trap you behind a permanent wall. After the set, you choose whether to leave or continue.

4 exercises · Easy, medium and hard

Different by design

Traditional blockers rely on a switch that can be turned off. Cairn changes what happens before that switch matters.

Four exercises: Choose push-ups, squats, plank or jumping jacks.
Adjustable intensity: Easy, medium and hard adapt the target reps or hold time.
Choice stays yours: Cairn puts the exercise first, then returns the decision to you.
