How does it work?
Let’s say you’re located somewhere on Manhattan, NY. You’re in a hurry for an urgent meeting? Going on a date, but you don’t have a car? You’re a rock star and need a to get yourself and equipment to the concert? In less than minute, you can call a cab. Without even having to raise your hand ?

Setting up option for current ride, choosing the destination, costs overview, confirming you reservation
In less then a minute, a list of nearby drivers is obtained. Location of the assigned driver can be monitored while waiting. You can also see the driver’s name and check the plates and car model so you can find him easier in the crowd.
You can monitor your location and estimated remaining time during the ride. Make a stop for cofee and monitor the status while your driver is waiting.
You can also rate your driver from the application, notify your friends about the ride (which provides you with extra credits for future rides, Dropbox style) and leave a status about your ride on your favorite social network.
The whole thing is very transparent regarding payment, which is made directly from personal credit card or business account. You can also see how much the ride will cost in advance.
What does it have to do with us?

As a solution Cloud to Device Mesaging was used. It’s a large enough topic for another blog post, so we won’t go into details here. As an example, one of the cases that had to be solved was periodic refreshing of the application registration to C2DM server.
Another important thing is that real drivers in NY are behind all this. Durring debugging and testing process it was necessary to use additional precaution measures so the drivers don’t end up waiting for somebody that will never show up.
