The use of Android smartphones has increased in recent years. As a result, there has also been an increase in the number of application installation. Many repair shops offer application installation services for customers. However, the installation process is too lengthy that it involves a lot of processes. The purpose of this study is to create a PC application that makes the installation of Android application convenient through wireless installation to multiple Android devices. The proponents used experimental research method. In the process, a survey was conducted to determine how simultaneous installation of Android application to multiple Android phones in a wireless local area network can be helpful in different individual and in different situations. In the development of the application, Incremental Process Model was used. In the end, the researchers selected students in the University of the Immaculate Conception for the evaluation of the application. The evaluation, which was in the form of a survey, revealed that in order for the desktop application to be able to be able to install applications to multiple devices, several technical factors have to be considered and be done. In conclusion, the application was able to conveniently install Android applications to multiple devices.
