This app converts your Apple iOS device into a Cat Years Calculator App.
The user clicks the Cat Years Calculator app icon then they are taken right into the app. They are greeted with a title on top which reads "Cat Years Calc", then under a label which asks "How old is your cat?". Followed by a Text Field box for entering a number. Rite below is a button that is labeled "Get Age in Human Years". Then just under the button is a label field which is blank when the app launches. Followed by a graphic cat image in the bottom part of the app.
As the user clicks the Text Field, a Number pad pops up and then the user types in their number and hits the button to get their result. The answer is shown in a label right below the button with the following example text: "Your cat is 63 in Human Years". The user can keep on entering different numbers to get an approximation of feline to human years.
Note: a factor of 7 was used in the equation to get the human years calculation in this demo app.
The Cat graphic used in the app was found on Wikipedia and the one used in the icon was found on freepik.com.
