The Philosophy Behind "Wrong"

In our fast-paced digital world, we've become too comfortable with seamless, frictionless experiences. While efficiency has its place, we believe that introducing deliberate friction in the right contexts can enhance our cognitive abilities and awareness.

The Wrong Calculator challenges the assumption that all digital tools should be as easy and automatic as possible. Sometimes, making things slightly more difficult can make us better thinkers, more attentive users, and more mindful humans.

"The best innovations come from questioning what everyone else takes for granted."
