Due Gooder turns your syllabus into a semester you can actually see. Upload a PDF and we pull out every assignment, exam, and class meeting, then organize it into one clean schedule by course — no typing deadlines in by hand. Then it keeps you ahead of it. A morning summary of what’s due, reminders before each deadline at the intensity you choose, and a heads-up 30 minutes before class starts. Home Screen widgets put what’s next in front of you without opening the app. And when it’s time to actually study, Due Gooder works from your own material.
