Most schools have a two or three-day block rotation. Others might have a block rotation that lasts a week. At my school, for some reason, we had a 15-day block rotation. Already difficult to memorize, the occasional holiday or half-day would push the block order around. Needless to say, many students were late from walking into the wrong class.
Originally developed by a senior at my school, the WPGA Schedule App provides up-to-date, offline access to student schedules and the block table. After his graduation, the original developer passed the app down to me, and I am the current maintainer of it. I have also written and released my own Android version to supplement the existing iOS version.
The WPGA Schedule App will be passed down to another coder when I graduate.
