## Review summary

Users largely praise the English-Japanese dictionary for accurate definitions, easy-to-use interface, and its value as a long-standing, trusted study resource. However, a pervasive set of issues detracts from the experience: intrusive ads and performance problems slow or block access; the app is prone to crashes; login churn (frequent forced logins, difficulty staying logged in, and password issues) frustrates users, sometimes prompting cancellations of the pro version. Some users report regression after updates, making the app harder to use. Overall, strong content is undermined by reliability and usability flaws.

### Pros

- Accurate definitions and rich explanations make it a trusted resource for serious learners.
- Easy to use with comprehensive content and helpful language explanations.
- Longstanding, widely loved dictionary that many users rely on for years.

### Cons

- Intrusive, full-screen ads that disrupt navigation and make it hard to return to the dictionary.
- Frequent crashes and instability; searches sometimes fail to return results even with a stable network.
- Repeated login requirements and difficult login flow, with password issues and no convenient credential saving.
- Slow performance and delayed search results; at times no results appear.
- Usability can degrade after updates, with some users reporting it becoming unusable.
