NetSpot is designed for mac users that want to scan all WiFi connections in an area and find/sort them as needed.
Is measuring signal strength, it helps to visualize wireless hotspots and to change their placement in house/office for better coverage and performance, view connections with problems and helps to resolve them.
It shows a list with all available connections, you can sort them by connection quality and strength, filter by security (connections that requires passwords or not), noise level and last seen date.
It shows the name of network (SSID), channel, band, signal and noise levels and security type.
Is good to be used at home or in public places (to detect free internet connections with good signal).
