This project is an iOS app called Chrono Count, which I developed in my sophomore year of high school. For more information, see my website here. This is very old code, and I do not know if it still works. However, if you are interested in this project, please feel free to contact me at firstname.lastname@example.org and I would be happy to answer any questions you might have.
The website apprisingsoftware.com used to contain information about Chrono Count. Since Chrono Count is no longer available for download from the App Store, I took this website down. You can view its contents in the Website subdirectory of this project.
