WiFi Solver FDTD by jasmcole is a simulation app for android powered smart devices that helps you strategically place your WiFi router in the best possible location in your home. The user uploads a floor plan in PNG file format then allows you to mark the position of your WiFi router, the app then simulates how the electromagnetic waves propagate giving you a good idea of where the potential “Dark Spots” may occur. Instructions on how to create, edit and upload your floor plan are carefully detailed on the developers Google Play page and only takes a few seconds to run.
