There are many programs for the PC to keep an eye on your network. But yes, nowadays we are less and less behind the PC and more and more often on the couch with our mobile toys. A mobile network scanner is therefore not an unnecessary luxury and Frank Portegies found one in the form of Fing. Fing scans the network the device is on so you can see exactly which other devices are in contact with that network. If there is something unknown or unwanted, you can easily block the culprit. In addition, Fing scans all active network processes per device.
