Can anyone tell me how this program works?

I thought the Poketmon game is for cellphone game with GPS.
How to play this game? with laptop?

 

Yes, you can use this software with any computer and windows installed (Win7-Win10).

For example, when you are at your work place, you can set up the bot to walk around there and catch some pokemon and visit the pokestops there, or at any other place you always wanted to farm pokemons.
