In a public area where there are are several public networks for you to choose from, you will want to check WiFi network strength and connect to the strongest one. On iOS, if you want a cursory look at which network is stronger, you need only open the Settings app. Select WiFi and wait for the available networks to be listed. Look at the little WiFi icon next to each network.
The number of filled arcs will indicate which is the stronger network. If you want a more precise reading on the signal strength, you can install an app called AirPort Utility by Apple. The Access Points tab shows many essential details.

One feature we liked allows saving notes to individual SSIDs, which are then included in any data exports. The Frequency Usage tab displays channel visualizations for the 2. They do the job of showing channel usage including channel-bonding and signal strength, but it would be nice if they had a single view of the entire 5GHz band instead of dividing it into four different graphs. For a free application, Homedale offers great exporting capabilities.
It supports saving the network list as a CSV, logging networks from every scan useful if moving while scanning , and saving an image of each graph. Although the GUI is very simple, Homedale provides some advanced functionality. We were impressed with its exporting, logging and location-aware features.
LizardSystems offers a free edition of their Wi-Fi Scanner application for non-commercial use, which has the same features and functionality as their paid product. This is a review of version 3. In addition to the Wi-Fi stumbling, it offers some great analysis and reporting capabilities. Along with the typical details, it shows signal strength in both negative dBm values and percentages. It even shows the number of clients connected to each SSID.
Along with specifying the You can use a list on the left to filter the SSIDs shown based upon the signal level, On the bottom of the Scanner tab, you can flip between several graphs. In addition to the typical signal level and channel usage graphs, there are visualizations for the data rates, channel utilization and the number of clients.

Wi-Fi Scanner would be a great one to add to your Wi-Fi surveying tool chest, while remembering that the free edition is licensed for personal use only. We were impressed with the filtering, advanced packet details and the reporting feature. NetSpot is a Wi-Fi stumbler and map-based survey tool, but for the free home edition we reviewed, the map-based survey tool is disabled. We reviewed version 2. The Netspot Discover tab is their Wi-Fi stumbler.
The signal levels are shown in negative dBm values current, minimum, and maximum and percentages. However, it does not show hidden networks at all on the network list. Clicking on the Details button on the bottom of the app reveals a combined signal graph and channel usage graph for each band, which conveniently highlights the SSID on the graphs based upon which is selected from the network list. We found the free edition of NetSpot provides a good Wi-Fi stumbler even though it does not supporting hidden networks.
The higher, the better. The tool captures packets from a given channel and saves them to a file.
