during a self learning process, the app will "learn" all networks (cell towers, base stations) that are used by your phone.
after the self learning process if this app should happen to detect one of these "cell spies", you will be warned by an optional sound and/or an optional red screen. the simplest way to avoid being listened in on, is then to turn off your phone for a while, or at least to keep silent.
when the app detects a network that is not included in its internal database, it will consult an external database of networks. if the network is not found there, it is assumed to be unknown.
features:
very easy to use self learning process periodic checks for networks selectable network checking period logging of all events internal (self learned) database integration with external database (opencellid) optional detection, logging and warning of "unknown" networks even attacks only lasting for a few seconds can be detected measurement of duration of attacks list of all identified networks export of csv file analysis of current and historical network data warning level assessment support for gsm, umts/wcdma, cdma and lte battery saving design using a "passive" gps location technique, to save power internet access is recommended, but not necessarily required internet access will improve the detection quality of unknown networks always running in the background, even when phone "sleeps" auto restart at boot time rooted phone not required no special phone/hardware required also works on tablets with sim card lots of answers to faqs info about "fake cell towers", "stingray", etc
