About this app

The child opens the book, and the parent checks it.

**Book Open!**, the place to collect your child's study materials and learning records.

From workbooks currently being worked on to textbooks already finished and even the next books to buy. Start managing study materials conveniently with Book Open!, replacing the reliance solely on memory.

• Separate bookshelves for each child

Separately manage the study materials and learning records of multiple children. You can organize them by grade and semester, from daycare and kindergarten to elementary, middle, and high school.

• Registering materials starting with photos

Take a photo of the textbook cover or select a picture to recognize text and help input textbook information. Check the recognized content and add necessary details. You can also register materials directly without a photo.

• How far you've progressed at a glance

Record progress by page and the date of completion. You can check both ongoing and completed materials together in the progress chart by grade and semester.

• Today's study and weekly plan

Set the days of the week and daily target amount for each textbook. Check today's study schedule and easily record what has been studied. In the learning calendar, you can review the records accumulated day by day.

• A purchasing assistant to reduce duplicate purchases

Before buying a new textbook, check if it overlaps with registered family textbooks. You can store books you are hesitant to purchase in the purchase drawer and move them to your bookshelf after buying them.

• Notes and reviews to help with your next choice

Leave notes, star ratings, perceived difficulty, and reviews for each textbook. You can look back on which textbooks suited your child well and use this as a reference when choosing the next one.

• Learning management for the family

By connecting guardians with an invitation code, you can view and edit your child's textbooks and study records together on their respective devices.

• Small joys to encourage consistency

Grow and customize your book character as you accumulate study days. Add to the fun of studying consistently with the "Open Book Race" with family and friends and by comparing records from the previous week.

• Backup and restore to preserve records

Back up everything from your child's profile to textbooks and study records as files, and restore them when needed.
View your child's workbooks and textbooks at a glance! Manage learning progress, weekly plans, and even check for duplicate purchases with Chaekpyeo!
