You Animal!

"You Animal!" is an Android app that allows you to convert from one animal's age to another. The user inputs an age, picks the source and target animals from a vertical scroll wheel, and the input age is converted -- either at a push of a button, or automatically upon any input changes.

How to use:

1. Input an age in the top left corner of the screen.
   
2. Scroll up and down the left column to find the animal you want to convert from.
   
3. Scroll up and down the right column to find the animal you want to convert do.
   
4. Press the "CONVERT" button at the bottom of the screen. The result will be rounded down to the nearest whole number.
5. Alternatively, check the "autoconvert" box in the top right corner of the screen. The result will instead update any time an input is changed.

Design choices:

• I wanted an intuitive layout for converting between animals. I settled upon two vertical scrolling columns, adhering to the English phrasing for converting, i.e. "human to sheep". While this design is readable in left-to-right countries, it would likely have to be adjusted for non left-to-right countries.
  
• The selected choice from the column is in a larger, bolded font for indication, with a "scroll-to-grid" animation to enforce alignment. 
  
• I rounded down results to the nearest whole number at the end because I didn't think the user should have to deal with decimals. If I had more time, I would have liked to offer an "accuracy" mode where the result would offer months/days as well.
