Cabubble is very straight forward to use, it's also very good at matching your journey to the best rates.The app itself is very simple and easy to use. Cabubble can sometimes take a long time to return your message and sometimes you may not receive any reply at all. I would recommend checking out the competition, especially the pricing. Cabubble has a great pricing structure which makes it very competitive. We have been able to cut down on the time we spend on the phone and the time we spend waiting for a taxi.
