The primary reason for Kuaiyong popularity was it allowed the user to download and install lots of free and cracked apps within their iDevices. Before this release, Jailbreak was necessary to install Kuaiyong applications on iDevices because Cydia installer was required to install these apps and that was impossible without the jailbreak. After the release of Apple iOS version 9.2, vShare, AppAddict and Kuaiyong applications are the most favorite apps downloaded by a huge number of users. Kuaiyong is a software that provides you facility to install paid apps on any iOS device without any cost.
