Abstract: A computer-implemented system and method for context-based APP searching and APP use insights are disclosed. User data is received from a plurality of mobile devices, each associated with at least one user. The user data includes context discriminators for each user and sensor data regarding the usage of applications on the users' mobile device. The data is stored and analyzed by an engine that identifies a list of names of applications used by each user on the user's mobile device. The engine provides to at least one user insights into applications used by other users by identifying the other users in a similar context to the at least one user based on their discriminators, and providing to the at least one user the names of one or more of the applications on the lists of applications used by the other users in the similar context.
