504 - Vocabulary Builder
large mismatch with reviewsA mobile version of the '504 Essential Words' textbook in flashcard format. Cards include words, example sentences, and TTS pronunciation. The problem is that TTS is unreliable a critical flaw for a language learning app. An update also locked the second half of the book behind a subscription without notifying existing users.

About the rating
Store average 4.77 vs text average 3.51, 44% five-star reviews gap is too large. Several five-star reviews are clearly from a non-English-speaking audience with minimal content, including one made entirely of emojis.
A mismatch is an analytical signal, not proof that the rating was manipulated.
