Catculator ($0.99) by FPO Projects Inc. is a cat! And it’s a calculator! Is there anything better than a calculator designed to look like a fat orange tabby cat? Say goodbye to that mundane, boring, black and gray default iOS calculator and download something with a little more personality. Catculator features an adorable cat with calculator buttons on his stomach and occasional animations. Catculator’s eyes move around, and leaves fall from the tree he’s hanging onto.

That’s not all, though! When you type in calculations, Catculator gives an occasional irritated meow. If you find it annoying, there’s a handy options menu where you can turn off sounds, but I enjoyed having people wonder what the heck I was doing with my phone. If you give Catculator a rub, he’ll launch into purr mode, or you can give him a shake to hear more of that exasperated meowing.
