See how long it has been, understand your current pace, and decide what feels right—without streaks, pressure, or judgment.
“When did I last do this?”
“Am I doing it a little too often?”
“Is it about time to do it again?”
Koroai helps you record everyday activities and understand their frequency and intervals.
“Koroai” is a Japanese word that means “the right time” or “just the right moment.”
Whether you want to build a habit, adjust how often you do something, or simply keep a record, Koroai lets you choose a pace that works for you.
■ See how long it has been
Quickly check how many days have passed since the last record for each item.
■ Set your own guidelines
Create guidelines such as “every few days,” “a few times per week,” or “a few times per month.”
These guidelines are not used to judge success or failure. They are simply there to help you decide what to do next.
■ Review your history
Use the monthly calendar to see when each activity was recorded.
■ Add comments and photos
Optionally attach a comment or a photo from your device to each record.
■ Get gentle reminders
Receive a local notification when an item may be approaching the interval you set. You can also enable an optional daily recording reminder.
■ Back up your records
Export your items, records, comments, and settings as a backup file and restore them later.
Photos themselves are not included in backup files.
■ No account required
Your records are stored locally on your device. No sign-up or login is required.
Find a pace that feels right, without judging yourself.
Koroai is a simple record-keeping app designed to support your everyday decisions.
