Fing is a top network tool for Android devices that can tell you everything that's happening on the wireless network you're connected to. It's free and worth a try.

It's a suite of network tools that will help you discover which other phones, tablets, and computers are connected to your Wi-Fi network. You can name each device you see on your network with a name of your choice, so you can quickly and easily identify which connections are your partners and which are intruders or just guests.
Although most routers provide this information, however, if you use repeaters to extend your network range, you may not have a list of users connected to the repeater devices. This is as far as your own network and your own router are concerned. If it is a third-party network, then you clearly do not have access to the third-party router and therefore no access to the corresponding information. However, with Fing, things change.
Fing is a completely free application, used by millions of ordinary users and professionals around the world. That's why it has 10-50 million downloads on Google Play. The application has frequent updates and upgrades, with the last one being dated December 14, 2017 .
