Works well but the info is vague – Wi-Fi SweetSpots Review

Assuming the app is correctly calculating the data transfer rate, this app is very helpful. But why not also show the Wi-Fi signal strength like RSSI and dBm? What about 2.4 or 5 Ghz and the current channel? This app seems to show the MAC address of the first Access Point it started with, even if the connection switches to another AP or the original AP is turned off, this app never refreshes the MAC.
