Truespeed 4G 5G WiFi Test is a free, ad-free app that provides fast and accurate internet speed tests. It is developed by NET CHECK GmbH, a quality assurance market leader in Germany. The app tests your internet connection for any type of network (2G, 3G, 4G, 5G, Wi-Fi) and various applications for their connection quality. It offers a map view with extended information of the test results and many useful test functions, including performance test, YouTube speed test, browsing tests, and app performance tests.

The app is easy to use and offers a comprehensive overview of your internet connection, including connection quality at your current location, map view of network coverage in the surrounding area, WiFi analysis, upload speed, download speed, ping latency, and information about the WLAN network, the mobile network, and the device used. The test history function allows you to compare current with past test results, and the app also provides information about the provider performance of the selected location. However, it is important to note that NET CHECK stores data about the user location, the network, device information, and data traffic.
