## Review summary

Overall, reviews praise the app for its practical vocab learning features—topic-based study, daily word goals, and varied tests—and for helping assess English level. However, there are reliability concerns: several users report crashes during word searches or tests, and some cannot download vocabulary or experience flaky downloads. The tone is mixed: strong interest in the learning tools but reliability improvements are clearly needed before recommending wholeheartedly.

### Pros

- Rich vocabulary learning features: topic selection, daily word quotas, and multiple tests to boost memory.
- Easy to use and engaging, described as practical and useful by many users.
- Useful for assessing English proficiency through quizzes/tests.

### Cons

- Crashes and stability issues, including crashes during word searches and testing.
- Vocabulary download problems, with reports of being unable to download or intermittent download failures.
