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. Record a lecture and get chapter-marked audio with AI notes. Turn your slides and readings into flashcard decks or a practice test that feels like the real exam. Keep everything in your Locker and search across all of it. Duey, your AI study assistant, knows your classes and can answer questions about them.

Verdict

The call

The clearest difference is rating: Codon at 5.0 against Due Gooder's 3.3. Codon also leads on update cadence (monthly vs every 4 months). Due Gooder's advantage is ratings volume (47 vs 1) and chart position (#196 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
