Furthermore, with a well-done measurement, it's possible to compare what was contracted with what is actually reaching your device. Some apps also offer test history, allowing you to track performance variations throughout the day, which is very useful for reporting problems and reporting them to your service provider. Therefore, let's present the best apps for testing internet speed.
