We need an app on android environment working in this way:

1 – 4 fields linked to contacts on the phone (1 date, 2 int, 1 multiple choice) with data entry. A button that will change the date to current date

2 – a daily task changing recorded image of the selected contacts (the algorithm that will handle the change will be provided to winner) superimposing a new image over the original. The superimposing image will be 3 or 4 different. The original must be kept somewhere.

We need the source code too
