This software generates a map of Pokemons near a specified area. It will tell you how much time you have to catch the monster and the exact location of it.
It requires python and is better suited for someone that isn't afraid of typing one command or two in the command-line.
It uses different accounts to scan different areas to provide a fast coverage of the area. Since this accounts are runned automatically they will (sometimes) encounter a captcha that needs to be solved. This software is already prepared for that and uses the 2Captcha API to send the captchas to be solved here.
