WiFi Analyzer by Abdelrahman M. Sid

The mobile solution has an intuitive design and enables you to discover an extensive set of information about your WLAN in just a few seconds. It aims to be an excellent option for anyone who plans to optimize their Wi-Fi connection, boost Internet speed, and increase network stability.
The app automatically detects all nearby access points and reveals a bunch of valuable details about each of them. For instance, it lets you identify not only their SSIDs but also their MAC addresses, encryption protocols, frequency, and the number of channels. Furthermore, it measures their signal strength and updates values in real-time to make sure everyone receives accurate information.
Likewise, the Android solution analyzes network channels to help users detect and decrease possible interference. For that reason, it enables them to explore a series of graphs and thus better identify network issues.
In addition to all that, the application recommends the best channels for new access points and lets you export reports to email, WhatsApp, or other services. It also provides a batch of extra benefits via a premium subscription.
