Are you bored and lonely?
There is nothing to do at home or at work?

No problem!

Come to the window, run the application and start to count the crows!

Have you seen a crow? — swipe your finger to the right.
Has the crow flown away? — swipe left, let the flies themselves.
Have all the crows flown away? — shake the phone and start to count the pigeons. (Swipe down on the watch)

And also you can count:
- Number of floors in a building,
- All vehicles in red, drive past you,
- The number of stars in the sky (for advanced)
- And in general everything that can be calculated.

Good luck!
