About this app

Solving problems again after looking at the solution isn't solving them on your own.

Chaejeomi follows your child all the way to the end, ensuring they solve the incorrect problems on their own until they get them right.

Grading your child's workbooks every day, making them re-solve the wrong ones, and nagging them to "solve it again"... now leave that to Chaejeomi. Instead of spoon-feeding solutions like a tutoring academy, it helps your child develop the ability to find answers independently.

■ Here's how Chaejeomi helps:

· Grading done with just one photo — Simply take a picture of the page your child solved, and it will grade it. It relieves the burden of daily grading for parents.

· Re-solve until right — It doesn't just skip over incorrect problems. It solves them again until they get it right, helping them reach "true understanding."

· Focus on the "solution process," not the answer — It filters out guesswork and focuses on critical thinking skills.

· Hint only once — It doesn't spoon-feed the answer. It preserves the joy of self-discovery.

· Just one day's worth — Keep it consistent without pressure, and let them play to their heart's content with the remaining time. · Use the workbook you are currently using — Any math workbook is graded instantly via photo.

■ Your daily routine changes

· Nagging by Chaejeomi, praise by the parents — Leave the nagging to the app, and parents can focus solely on praise.

· At home without tutoring — Instead of a late-night shuttle to academies, build a habit of studying independently at home.

· Learning records by child — See how much was solved today, questions answered correctly again, and progress at a glance. Siblings can also be managed separately.

■ Use with peace of mind

· Sign up with parental (legal guardian) consent.

· No ads, and the app does not track the child's usage behavior.

· Data is encrypted and stored securely, and you can delete your account and all data at any time if you wish.

The power to solve problems independently until the end. Chaejeomi follows the child right by their side until the very end.
Solve incorrect problems on your own until you get them right! Take a photo for grading and re-solve wrong answers — a math habit to do at home without an academy.
