What is the difference between the web version and the mobile app?

DORS is available on iOS, Android, and the web, with the same current feature set across all three. Use one account across platforms, and your learning data syncs between them. Choose the environment that works best for you, whether that is your phone or the web.

Can beginners use DORS?

Yes. You can check translations and practice at your own level. DORS helps beginners start with guided practice instead of jumping into difficult conversations.

What does the English speaking assessment check?

The assessment checks four dimensions: pronunciation accuracy, pronunciation fluency, semantic relevance, and natural semantic expression. The results help DORS create your learning plan and suggest practice tasks.

How does the personalized learning plan work?

DORS uses your assessment results, recent practice, pronunciation history, and scenario progress to suggest daily tasks. Scenarios are matched by the system rather than entered manually as a plan input.

What can I practice with scenarios?

You can practice English for real-life situations such as airports, hotels, cafes, restaurants, shopping, work, interviews, and travel. You can also create custom scenarios based on your own goals.

Which interface languages does DORS support?

DORS currently supports Japanese, Simplified Chinese, Traditional Chinese, Korean, Indonesian, Spanish, and Russian as interface languages.
