Job description
I will commission the creation of a simple application for Android.
This application is to be an addition to the water tests. Performing a test of water is based on adding a reagent to water and comparing the color which takes the water with printed pattern. On the pattern there are color fields arranged from the lightest to the darkest. The field which has the same shade as the analyzed water sample indicates the concentration of the tested substance in water.
The application is designed to replace the printed template. After choosing the desired test from the main menu, the application should display a colored square (color numbers will be provided by us). At the bottom there should be buttons labeled "Lighter" and "Darker" and "This one". When the "Lighter" button is pressed, the color of the square should change to a lighter shade (color numbers will be provided by us) and similarly, when the "Darker" button is pressed, it should change to a darker shade. After pressing the "This one" button the application should display the concentration of the tested substance assigned to the given shade of the square.
The app is supposed to be very simple to use. As the description shows, it is not complicated as far as the offered functions are concerned. The graphic interface is supposed to be clear, aesthetic, and simple.
