PHILADELPHIA (CBS) – On today’s APP-tastic and outta SITE – LeftyCalc.

It’s International Left Handers Day (seriously – check your calendar). So, to celebrate, we present to you LeftyCalc.

This calculator app is built specifically for left-handed people, with the numbers and action buttons reversed – so, instead of reading 1-2-3 along the bottom row, it reads 3-2-1.

It’s a nice thought, but it might require some unlearning – even amongst the left-handed.

Check out the LeftyCalc app.
