Crowdsourcing
Since launching in 2010, OpenSignal has built the largest global database on mobile performance.

With hundreds of billions of readings of mobile network signal strength and speed tests, OpenSignal shows the performance where you live. Download the app to automatically contribute data on speed and 2G, 3G and LTE signal, or you can choose to turn off data collection settings.

Want to check app performance - know if you can get fast video on Youtube, or if WhatsApp will send messages - check our sister app Meteor which is powered by OpenSignal technology.

Permissions
LOCATION to show you nearby wifi and antennas
PHONE SETTINGS allows network reset on some Android OSs
SMS to count the number of SMS sent to track your usage, SMS are never read (use a packet sniffer to check!)

Advanced Notes
