| Support quality | Only support-email discount mention found | Per-developer support; abandoned apps reported. |
| Public sentiment | Reddit users praise it for combining flashcards and tests from their own materials, and Google Play ratings are solid but modest at 4.2/5.⁸ | Merchants value the selection but flag inconsistent app quality, dubious reviews, and abandoned third-party apps. |
