Over the past year and a half, we have been working relentlessly to reinvent our product so that you can deliver mobile applications that your users will fall in love with. In this session, we'll show you how building mobile apps has changed from previous versions. We will start with the challenges you have building them. We will walk you through each hard decision and tradeoff we had to make along the way. Finally, we will explain the revolution we had to do under the hood to make all of this possible.
