The Subscription Trap

Those $9.99 charges you never think about? Drag the sliders and watch ten years of them stack up.

The little stuff you forget about

Drag the sliders to match your actual life. These tiny "I won’t even notice it" charges add up way faster than you think.

Default Bias is why auto-renew is always pre-checked. Turning it off means you have to decide every month, and that one extra step is the gap between the red bar and the green one.

Quick test

The Framing Effect

Same money, two ways of saying it. Pick one and see which frame most people fall for.

The setup: You're handed $630. Choose how it's described to you. The money outcome is exactly the same either way.
Both options leave you with exactly $210. Identical math, different feeling.

Pick one and see how most people choose

We'll show how everyone else picks and why the words matter.

Background

What's going on under the hood

Default Bias

Whatever box is pre-checked is what you keep forever.

People stick with the option that is already picked, because changing it takes effort. Companies set that option to whatever pays them.

Framing Effect

Same math. Different words. You pick differently.

Calling a choice a win or a loss flips your answer, even when the outcome is the same.

Decoy Effect

A trash third option exists just to push you to another.

Companies add a deliberately bad option so a different option suddenly looks like a no-brainer. The bad one was never meant to be picked.
