Meteor

Most applications that measure your Internet speed don’t provide an accurate picture. Most of the times they just offer the peak and low end of the spectrum, but that’s usually not the overall experience of the user. People get something that’s in between, meaning that they most likely won’t benefit from the top speed reported by the testing app.
This is where Meteor comes into play, aiming to provide much more accurate data and more relevant for the users. The app takes some of the regular apps and benchmarks them while using the Internet. In this way, users can get a fair assessment of the Internet speed that’s actually closer to the user's experience.
The apps supported by Meter are the following: Chrome, Dropbox, Amazon, Facebook, Flipboard, Gmail, Google Maps, Instagram, Skype, Spotify Music, Street View, Twitter, Uber, Waze, WhatsApp, and YouTube.
