The entire KRON system is a multi-target application written in Swift. While many portions are written using UIKit, underlying functionality required more performant frameworks. As such, CoreImage, Quartz, and OpenGL, were used to create many underlaying technologies that were integrated into the main application. The app required dozens of API integrations to input the users data and provide the visualizations. A customizable theme system was also implemented. The theme system used Firebase as a server-less backend, allowing the client to create real-time design updates that were instantly visible on the app.

KRON is an innovative application designed to visually enhance and integrate multiple data types such as calendars, RSS feeds, music, health data, and more. Leveraging mainstream calendar APIs and the power of OpenGL custom graphic shaders, KRON delivers stunning visual effects, transforming the way users interact with their data.

The successful completion of the KRON project resulted in a highly engaging and visually captivating application that redefined how users interact with their calendars and other data. The integration of multiple data types and the use of advanced graphical techniques set KRON apart as a leader in data visualization tools. This lead to a position on the "Apps We Love" list produced by Apple.
