Test Master funktioniert nicht

Test your current network connection speed, and give corresponding network suggestions according to your current network speed.  If your network status is not good, don't play online battle games, so as to avoid bad game experience from affecting your mood.  IP Test and Network Test are very easy to use, allowing me to know the current network status at any time.  Test if your WiFi is secure:When you are away from home, don’t connect to unfamiliar wifi at random, you need to ensure the security of wifi.  Hello everyone, I don't think the WiFi tools in the App Store are very good now, so I wrote one myself.  Detect the number of devices you are currently connected to WiFi.  By displaying these devices, it is clear at a glance whether someone is using the Internet.  Protect personal privacy and security.  At present, there are several functions in the application that I often use.  I hope you can leave a lot of comments after using it, and together we will create the best network tool in the App Store! （By the way:If anyone is interested, we can develop it together!
