どこでもワーク　英語１年 is an educational app developed by 株式会社　文理. It is a comprehensive workbook that is fully aligned with school textbooks.

This app includes two main features: "Grammar Training," which consists of multiple-choice grammar questions, and "Vocabulary Training," which provides flashcards for English words. It is recommended to use this app on Android 4.0 or later.

With convenient learning functions, users can choose multiple units to study at once. The "Random" option allows for learning in a random order, while the "Retry" feature focuses on reviewing incorrect answers. Users can also choose to study only the questions marked with "Post-it" notes. Additionally, the "Vocabulary Training" feature allows users to listen to pronunciations.

To make learning more enjoyable, the app includes various engaging elements. The "Result Announcement" feature displays different images based on the number of correct answers. By completing all the questions correctly in a unit, users can earn items in the "Item Get" feature. These items are collected in the Curio Room.

Please note that items can only be obtained by solving a single unit in "Order" or "Random" mode. Selecting multiple units or using the "Retry" or "Post-it" options will not yield any items. Furthermore, once an item is obtained for a unit, it cannot be earned again in subsequent attempts.
