The OpenSignal app is a free and ad-free network signal & wifi tool. By testing the true speed of your mobile and WiFi connection, comparing the quality of coverage across major operators and mapping out Wi-Fi hotspots across the globe, it helps you get better network connection instantly.

Since launching in 2010, OpenSignal has built the largest global database on mobile performance with over 20 million downloads to date.

Anyone using the app contributes data. This means that information you get from OpenSignal comes from our millions of users like you out there. We’ll never ask you for personal information, just your signal stats, and take care to use as little processing power and battery life as possible.

We use these data to increase transparency in the wireless industry by publishing reports on the quality of mobile networks, offering unbiased coverage maps and empowering people to get better mobile connectivity in a hassle-free way.
