CloudKit is Apple's cloud backend service and application development framework that provides strongly-consistent storage for structured data and makes it easy to synchronize data across user devices or share it among multiple users. Launched more than 3 years ago, CloudKit forms the foundation for more than 50 Apple apps, including many of our most important and popular applications such as Photos, iCloud Drive, Notes, Keynote, and News, as well as many third-party apps. To deliver this at large scale, CloudKit explicitly leverages multi-tenancy at the application level as well as at the user level to guide efficient data placement and distribution. By using CloudKit application developers are free to focus on delivering the application front-end and logic while relying on CloudKit for scale, consistency, durability and security. CloudKit manages petabytes of data and handles hundreds of millions of users around the world on a daily basis.

BunnyBolt is an interactive, maps-driven exercise game for youth. The app encourages physical activity by disguising in-app exercises with a youth-friendly storyline. Unlike games like Zombies, Run!, that lack a child-friendly fitness component, or games like FitQuestLite that cater too much towards children, BunnyBolt combines the fun of an interactive game with the practical concerns of workouts for an engaging app that is beneficial for all ages. Though our primary audience is youths who own smartphones, BunnyBolt's quick ten-minute workouts are appropriate for all ages. When developing this mobile application, our hope was to harness the elements of an engaging video game, and integrate it into an application that would encourage children to go outdoors and exercise.
