Anti Spy Mobile Free is a security app. Its main goal is to inform you if any other apps on your Android might be threatening your privacy.
When you open the app for the first time, it starts analyzing all the other apps on your device. This process can take between a few seconds to several minutes, depending on how many apps you have.
Basically, what Anti Spy Mobile Free does, is inform you if other apps are asking for 'suspicious' permissions. For example, some apps, without you knowing, might even have permission to read your text messages. This way, you can check if you really agree with that, or if you would prefer to delete the app.
Anti Spy Mobile Free is a pretty simple but useful security app. From its user-friendly interface, it lets you take a look at all the more intrusive permissions some apps might have on your Android.
