This was a fantastic app. The spectrum analyzer worked great. My original review was a 4 star. The just updated it, and touted how you can now view SSID information... What they neglect to make clear, is you need to purchase a new piece of hardware to do so. I dont need the power test leads, so luckily I didnt spend the big dollars on the full kit. But less than a year ago, I bought the wifi analyzer, and now, I either need to buy a new one, or not utilize the new features. Im an extremely small business, and dont have the money for an upgrade like this, in such a short period of time. It may still be the cheapest option, but this is a huge kick to the you know what for a small shop like me.
