ooring helps people who live together keep track of household chores and notice each otherβs effort. Create a shared space with your family, partner, or roommates, then add chores such as dishes, cleaning, laundry, taking out the trash, or any routine that matters in your home. When someone completes a chore, ooring sends a notification to the other members of the space. They can respond with a quick cheer to say thanks. Instead of guessing who did what and when, ooring keeps a simple shared record of household work and makes appreciation easier to send. Key features - Start with a nickname, no account required - Share a space with an invite code - Add household chores with simple icons - Record completed chores with one tap - Send completion notifications to members - Cheer for completed chores - Check recent activity and completion times - Supports Korean, English, and Japanese ooring also works well for people living alone. Use it as a lightweight home routine tracker and keep a record of small tasks completed each day.
