Speedtest.net uses a technology called Adobe Flash for consistent, accurate speed measurements. Unfortunately, this technology is not supported or poorly supported by many phones and tablets today. Our Speedtest.net website interface is also designed for a mouse or trackpad, and not touch screen interfaces.

To ensure accurate results, if you visit the Speedtest.net front page on your iOS or Android device, we automatically redirect you to our apps. For more information on our mobile apps, read How do I use Speedtest.net on my Android or Apple device?
