Differentiation Detector

Do you want to know if your carrier is violating net neutrality? Differentiation Detector tells you if this is the case, and how much they are slowing down (or speeding up) specific apps.

By running these tests, you will also help us create a public database of carrier behavior worldwide. This can help you decide which carrier to use in the future, based on the performance they give to your favorite apps.

Help inform the net neutrality debate by downloading and running our app! More details about the app at http://dd.meddle.mobi.

This APP is developed by researchers from Northeastern University and Stony Brook University.

Please excuse us if you encountered any bugs or crashes. We tried our best to make this app stable, and all crashes will be sent to our server for future improvement. No personal information will be included in the report.

Please be aware that this APP might not support your carrier because of the various network devices which your carrier put in your network. For more information, please check out our website!
