Do cab-hailing smartphone apps simplify our lives?

Madwoman (Ireland)

We have Hailo here, it's brilliant, I can just hail a cab, from indoors, and have it come to my front door. You know who the driver is, what he /she looks like and his phone number. Perfect for shift workers finishing at midnight. In return the driver knows who you are, you have to give your bank details when setting up the a/c so driver always gets paid, it's win win. The positive security aspects, especially for women, are obvious.
