Copy of android application Happy Kids Timer Chores

I would like to have a source code of a game like Happy Kids Timer Chores, does not need to have the chores animations - some simple images instead.

I would like to have in that application:
the ability to turn between portrait mode and landscape mode.
the ability to switch languages.
the ability to create profiles for more than 1 kid.
the ability to choose specific chore to run instead of running entire chore routine in sequence.
the ability to pause chore.
... maby a few more things
