mShout is a small business app that helps tra53rummy.comveling sellers announce their presence at a particular location to retail customers. With the rise of campuses and communities, there is growing physical separation between those selling goods from mobile carts and their customers. The app enables these sellers to 'shout' out their presence digitally to customers, in much the same way that they did physically. mShout is also integrated with Mapunity’s mPlaces app, and can be used from within that application as well.
