Neutrona Wand Free, developed by Mikey Apps, is an entertainment app for Android users. It is designed to simulate a proton gun, also known as the Neutrona Wand, that fires a beam of protons produced by colliding high-energy protons. The proton stream has the ability to hold negatively-charged entities until they are captured. However, it is important to note that this app is purely for entertainment purposes and does not have any physical effects.

Neutrona Wand Free does not fall under the category of games, but it can be an enjoyable experience for fans of the Ghostbusters franchise. The app is free, but there is also a donate version available that allows users to set the sounds from the app as ringtones and removes advertisements. Overall, Neutrona Wand Free is a fun app that can provide a brief escape from reality.
