A method, a computer program product, and a computer system modify a version of an application. The method includes determining a sentiment being experienced by a second user while using a second version of the application installed on a second device associated with the second user based on sensory information indicative of the sentiment. The method includes generating sentiment associated information associating the sentiment of the second user with the second version of the application, the sentiment associated information configured to be exchanged with the first device over an offline, ad hoc connection. The method includes transmitting the sentiment associated information to the second device. The sentiment associated information is indicative of whether the first version of the application is to be modified on the first device to the second version of the application.
