How is the durability of Vaia?
Vaia has 17 positive and 18 negative mentions in customer reviews. Sentiment is slightly negative, especially since mid-2025, due to rising issues with app stability and data loss. Users praise the clean interface, effective flashcard generation, and long-term reliability, with some reporting years of consistent use. However, more users report crashes, freezing screens, and lost learning progress, particularly after updates. Satisfaction declined from mid-2025 to early 2026, with multiple 1-star and 2-star reviews citing unreliability. Some users remain loyal and optimistic, noting the app works well when stable. Reliability concerns now outweigh earlier enthusiasm.
