OpenSignal: Map Cellular & Wi-Fi Signals

Free app for mapping cellular, Wi-Fi, and other signals in your area, crowdsourcing data from users' devices to build maps of network coverage and performance.

What is OpenSignal?

OpenSignal is a free mobile app and website that provides users with information about cellular, Wi-Fi, and other signals in their area. It functions by crowdsourcing data from the devices of users who have installed the app.

When OpenSignal is running on a user's phone, it passively collects information about the mobile networks, Wi-Fi connections, and other signals that device encounters. This includes data on the availability and strength of connections, download/upload speeds, latency, and more. OpenSignal aggregates this crowdsourced data from millions of users to generate detailed coverage and performance maps for cell phone carriers, Wi-Fi networks, and other signal providers.

Users can view these interactive signal maps on the OpenSignal website to see the quality and availability of connections in their neighborhood and city. The maps visually illustrate the differences in coverage and speeds across various providers. Users can also drill down to see detailed metrics on individual carriers, Wi-Fi networks, or other signals.

In addition to the signal maps, OpenSignal provides research reports, consumer insights, and other wireless intelligence. The data they gather via crowdsourcing has allowed them to become an authoritative source comparing and ranking cellular carriers, Wi-Fi providers, and other signals.
