Do you want to be able to make your iOS applications faster or slower? If so SpeedMaster promises this! The SpeedMaster Cydia tweak allows you to control the speed of your applications by simply switching a toggle. Most of the applications’ animations will change, some game engines will also be affected such as Coco2d, Coco2d-x, SpringKit and more. SpeedMaster offers a pretty UI and is easy to use. You can configure the tweak from the application on the SpringBoard (homescreen).
MoonWolf, the developer of this tweak notes that not all of the applications are effective, but he will support more in the future. If you are interested in downloading this tweak, you can find it in the default BigBoss repository for $1.99. Be sure to let us know what you think about SpeedMaster in the comments.
UPDATE: SpeedMasterFree is now available to download from Cydia in the BigBoss repo.
