This app would be much more effective if vocabulary were organized by frequency and real-life usage. Some words are essential for daily conversation (like “get”) and should be marked as high priority. It would help to show whether a word is used more in spoken or written English, include the most common conversational synonym, and add a conversation practice section to help users use these words naturally.

Thank you for your thoughtful suggestions 💙 If you use the “Most Used” filter in the word list section, you can already see high-frequency vocabulary more easily. We truly appreciate your ideas. With more user support through subscriptions, we’ll be able to develop and add even more features that users like you are looking for. 🙏
