InfoCub, the premier movie offline browser is the perfect offline movie review browser for a quick movie lookup, before the weekend movie trip, pay-per-view purchase or trip down the video store. Since INFOCUB is an Internet enabled application, your list of current movie reviews will NEVER grow stale! Every Friday, you can download new reviews just by clicking the "Update" option and a quick connection is made to the Internet (a few seconds), a small compact file with the latest reviews are downloaded and the Internet connection is closed. Every Tuesday the latest Top Ten list of movies of the weekend is also ready to download.
