Antenas de Telefonía Móvil is a free Android app developed by Fco. Javier Fernández Saavedra, which provides detailed information on mobile antennas and towers for all mobile telephony providers in Spain, including Movistar, Vodafone, Orange, Yoigo, and Euskaltel. With over 69,000 antennas (stations) mapped out, this app is a useful tool for those planning to travel or live in areas with poor coverage. The app also shows the operator, coordinates, direction, type of station, bands, and frequencies of the antennas.

One of the most useful features of Antenas de Telefonía Móvil is its ability to show users which antenna their mobile is connected to and the three closest to it. It also allows users to see areas with better or worse coverage, making it easier to plan their travel routes or choose where to live. The app also includes a map of all telephone booths in Spain and an emergency kit that includes a flashlight, SOS transmitter, red flashing emergency light, compass, and a walkie-talkie feature that can connect multiple devices via WiFi or Bluetooth without using an internet connection or mobile network. However, the app requires three permissions: access to location (GPS), audio recording, and camera.
