No matter what kind of smartphone people own, there are literally hundreds of thousands of apps available!
I think that one of the best is the Fastcustomer app. Why? From the consumer point of view, it is an additional 'reference desk' information or a 'chat-a-life' service. Fastcustomer waits on hold for the patron. There are 2,000 customer-service numbers, then, once the app has reached an actual human representative, it connects the caller -assuming the person hasn't hung up in the meantime.
