お手伝いコイン

New Bulk Mode lets you record several chores at once. Same-day duplicates now show an "already recorded" hint, so logging chores stays effortless.

A fun way to support your child's chores at home — together as a family.

[Main features]

• Record chores with a single tap and earn coins
• Register multiple children, each with a personal theme color
• Customize the list of chores to match your home
• Monthly history view with automatic allowance calculation
• Monthly Retrospective screen — celebrate effort as a family
• Backdate entries when you forget to log right away

[What makes it different]

• Simple, child-friendly design
• Coin animations and sound effects to keep kids motivated
• Fully offline — no internet connection required
• All data stays on your device only

Note for international users: Otetsudai Coin is designed primarily for Japanese-speaking families. The user interface is available in English, but the allowance amount is displayed in Japanese yen (¥) only. The app is well suited for Japanese families living abroad and bilingual households who want to maintain a Japanese-style chores-and-allowance routine.

Help your child build great habits and bring your family closer — one chore at a time!
