Electrosmart is an Android application which measures the radio-frequency electromagnetic waves emitting from various sources like mobile phones (cellular networks i.e., 2G, 3G, 4G, 5G), WiFi access points, Bluetooth devices, etc.

[1] The app was developed by a research team DIANA (Design, Implementation and Analysis of Networking Architectures) led by Arnaud Legout in partnership with Electronics, Antennas and Telecommunications Laboratory (CNRS and Sophia Antipolis University).

[7] According to IARC (International Agency for Research on Cancer) and WHO (World Health Organization), the electromagnetic fields generated by mobile phones may be carcinogenic to humans.

[12] The app alerts its users in case of high exposure and provides them solutions to create insulation from electromagnetic sources.

[7] By June 2018, app became more popular among the audience and received more than 64,000 downloads and 30,000 active users in addition to 850 million measurements.
