Making my first App

I have a long list of things I want to understand and make. Some of the entries on this list are apps. Back during the winter break I thought I would finally get the ball rolling and learn to make a simple android application. Of the apps I actually want

Where is the weather most variable?

Where is the weather most variable?

My PhD is about the predictability of the weather. To me, predictability means the rate of ensemble spread. Ensemble spread is how quickly computer simulations starting with similar weather disagree with each other. You could also think about it as how predictable a robot would find the weather. But what
