OpenSignal is an app and website that allows users to measure the performance of their mobile networks, such as speed, latency, and signal strength. It uses data from millions of users to generate maps that show the coverage and performance of both Wi-Fi and cellular networks in real-time. The maps are interactive and can be used to compare network performance in different parts of a city or country. The app also includes features such as a speed test and the ability to report problems with a network, as well as other useful information about the network, such as signal strength, data usage, and battery life. OpenSignal is an invaluable resource for mobile users who want to maximize their mobile experience.
