Disarray: Basic Calculator

The brain is known to be the first organ of the human body that dies of old age, which gives us our primary incentive for keeping it young and in shape.

Using a traditional basic calculator is a task that does not help keep the brain in shape. One particular reason is that we form a mental map of where the keys are located on the device or app and no longer have the need to learn much when using it.

The good news is that you don't have to try to become good at arithmetic and you don't have to ditch your basic calculator to help your brain stay in shape while crunching numbers. Now you can just use Disarray.

With Disarray, the keys change after each key stroke. This prevents the brain from being able to form a definite mental map of where the keys are located; therefore, your brain has to constantly work with its visual sensory data to use the basic calculator.

This app intends to keep your brain in a more wakeful state by increasing the amount of coordination that is required between more parts of the brain and the calculator; therefore, helping induce more blood flow in multiple regions of the brain.

You'll get the hang of Disarray with increased use. Give it a try!
