Andrew Walding President of CellStream Inc. telecom consultancy

Teaching Wi-Fi hands on skills for the last 8 years, we have used the latest and best tools. The release of WinFi not only ranks #1 on our tools list, it means re-writing our courses and labs to leverage its superior features and functions that leave all other Wi-fi analysis tools in the dust.

WinFi is an amazingly powerful and useful tool. I've used it to find WiFi signal issues throughout our home, and in my parents' 17th century stone farmhouse: Who knew that 3 foot thick stone walls could attenuate WiFi signals so much?! Thanks to WinFi (and the addition of some additional AP's and bridges), my folks now have great WiFi coverage throughout their home.

Absolutely best Windows WiFi Scanning tool that has completely blown my mind away today ;) Thanks Helge, hands down buddy.

Josh Schmelzle Senior Wireless Engineer

WinFi fills large gaps on the Windows platform that others have not. It is already my go-to application for protocol analysis of nearby networks. I highly recommend it.

Brett (Microsoft Store Review)

Where has this been all my life?! This is definitely the best quick analysis tool I have ever seen on windows. If there is ever a pro version that adds spectral analysis and remote sensor capabilities I'll definitely buy it. Keep up the good work!

Zeeshan (Microsoft Store Review)

Great Product. You don't see scanning tools such as WinFi in windows environment. Tool is written by someone who understand WIFI very well.

The number of feature for a free app are simply staggering and the UI is intuitive and pleasing to the eye. A great tool and must have for anyone in the networking sphere, especially if you're in a pinch and don't have equipment on hand. No other app of its type comes close!
