CMU Impromptu

Impromptu is a software distribution platform developed by the Human Computer Interaction Institute at Carnegie Mellon University. Our app provides users with "opportunistic apps" (apps that you only need once or twice), thereby allowing you to make use of apps if/when you need them, without having to have them permanently installed on your phone!

IMPROMPTU IS A RESEARCH TOOL, NOT A COMMERCIAL PRODUCT. Our app uses your phone's mobile sensors to determine which apps you may need, which in turn will incur a small drain on your phone's battery. By downloading/installing this app, you agree to give CMU access to the sensors on your phone (e.g., GPS, accelerometer). Additionally, Impromptu services are not guaranteed, and will change without warning/notification depending upon our research needs/goals.
