Network Signal Info Pro provides detailed information about the currently used network with accurate signal strength output, be it WiFi (WLAN) or cellular (mobile) connection and is easy to use, This type of software is ONLY available on Android smartphones , neither iOS nor Windows Phone Pro version (compared to free version) has no ads, a NEW cell tower database with more than 80 million entries, a NEW MOBILE SIGNAL TRACKING function that generates a KML file for use with Google Earth, plus widgets, a LOST SERVICE MOBILE SIGNAL and much more. I have worked especially in the visualization of the Wi-Fi and the strength of the mobile signal. They have received special importance. They are normally only divided into weak, good and excellent signals. Graphically, there are mostly "just" three to five bars that show up as a mobile signal and three "waves" that show up as a Wi-Fi connection.
