This free tool allows you to check how many people are around you
Have you ever wondered how many people you actually have around you each day? Then this might be the perfect tool to get that info. The howmanypeoplearearound tool by schollz is a free and open source project which allows you to check how many people have been around you by monitoring the MAC addresses that are seen.
The developer does smartfully state that the use of the application might be illegal in your country, so be sure to check the law before you try it out.
It may be illegal to monitor networks for MAC addresses, especially on networks that you do not own. Please check your country’s laws (for US Section 18 U.S. Code § 2511).
