Thank you for your review

Speedster is a native OS X client for the SpeedOf.Me Internet speed testing service. Run ad-free download and upload tests without the need to install Flash or any other plugins. Your test results will be saved on your Mac and can be conveniently displayed in an elegant chart or exported as a CSV file.

Important: You will need to use your own SpeedOf.Me API key or purchase consumable test packs to use the app. Speedster is not affiliated with SpeedOf.Me, and as such cannot assist with the process of acquiring a key. For more info, please read the FAQ: More...
