This is a great app for calculating anything related to RF. You can see basic information about the network (IP, DNS, SSID, etc), run a ping test, do a LAN scan, and more.
This is one of those apps that really comes in handy when your iOS device is the only thing you have access to. It’s free, but you can pay a small fee to disable ads within the app. I love running this on iOS devices in situations where deployments (K12, College, BYOD) might be heavy on iOS devices. While this isn’t always 100% accurate because it’s running over the live internet, it’s at least a simple gauge of how fast a device might be going.
While it’s not a substitute for a dedicated site survey toolkit, it’s handy in a pinch. No other app (due to Apple’s API rules) can access this information directly within iOS. It’s because it has a built-in Wi-Fi scanner. You might be wondering why I’m recommending Apple’s management app for its router for IT professionals. I’ve compiled the list of what I feel are the go-to apps that all IT professionals should have on their iPhone and iPad. The key for any IT/WLAN professional is to know which apps can help them do their jobs better regardless of where they are. Over the years, iOS (iPhone and iPad) has gone from an add-on device to a Mac or PC to a device that can be used nearly 100% of the time.
