Common complaints
Common complaints include technical issues and AI inaccuracies. The app crashes frequently, especially on tablets. The AI often misjudges correct answers. Users report the app does not respect preferences, such as disabling true/false questions or open-ended responses. Features like deck search and flashcard functionality are now locked behind a premium paywall, restricting access for non-paying users.

How it has changed over time
Quality perception fluctuated over time. Ratings reached 4.14 stars in December 2025, the highest point. They dropped to 2.75 stars in June 2026, likely due to new restrictions and technical issues. The app recovered in July and August, with ratings at 3.86 and 3.8 stars. Overall, quality remains solid, but recent changes have caused instability in user experience.
Practical takeaways
Vaia is a free study tool for students focused on content review and memorization. Key features like search and advanced flashcards are now premium-only. The AI assists with learning but occasionally marks correct answers as wrong. Users should verify results before relying on Vaia for high-stakes assessments.
