Verdict
The clearest difference is rating: StudyBuddy at 4.8 against GradeSync's 4.2. StudyBuddy also leads on ratings volume (218 vs 16) and device support (3 vs 1). GradeSync's advantage is in-app purchases (none vs 1) and update cadence (every 4 days vs every 2 months). On price, ads and monetization model there is nothing between them.

Both are free to download. StudyBuddy sells 1 in-app purchase, starting at $4.99 per month. GradeSync asks for nothing beyond the download.
StudyBuddy holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: StudyBuddy has 218 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 83% of StudyBuddy's written reviews are positive against 100% of GradeSync's, so the app with the better star average is not the one people write more warmly about.
StudyBuddy ships an update every 2 months, GradeSync every 4 days. Both last shipped on October 28, 2026.
