Is your mobile app or game built to run on multiple platforms? Do you want a fast, straightforward solution to common problems like data synchronization, player achievements and leaderboards? Amazon offers several services that allow you to plug-and-play features in your mobile app or game, with very little set-up and no server-side development. This session will provide step-by-step instructions for integrating GameCircle (Whispersync for Games, Achievements, Leaderboards) in your Android and iOS apps, and demonstrate how to add Insights (A/B testing) and fine tune your app based on user response. You will learn how to speed up your time to market, regardless if you distribute through Google Play or the Amazon Appstore.
