TimeOn is a shared calendar for families, couples, teams, and friends. Bring multiple calendars, labels, recurring events, holidays, and widgets together in one place.
Schedules are never truly ours alone. Family anniversaries, plans with a partner, team deadlines, and meetups with friends — our time is always connected to someone else.
TimeOn is a shared calendar designed from the ground up for the times we manage together. It is not a personal diary, but a collaborative space where multiple people can create, edit, and check schedules on the same calendar.
[Key Features]
Multiple shared calendars
Keep separate calendars for family, work, and friends inside one app. Start syncing with a single invitation link, and see updates reflected instantly.
Organize events with labels
Create labels with colors and names for each calendar, so meetings, personal plans, business trips, and anniversaries are easy to distinguish at a glance.
Lunar calendar and holidays together
Includes Korean lunar dates, plus official holidays for Korea, the US, China, Japan, and India. It also reflects substitute holidays and temporary holidays.
Precise recurring event control
Supports weekly, monthly, yearly, and even lunar-based recurring events. Edit or delete only specific occurrences to handle real-life changes with flexibility.
Offline-first design
Works the same on the subway or in airplane mode. When the network returns, everything syncs automatically.
3 home screen widgets
From the Today widget that shows only today's events, to the Weekly widget for a quick overview of the week, to the Monthly widget that opens the whole month — keep track without opening the app.
Multilingual support
Korean, English, Japanese, Chinese, and Vietnamese. Switch freely inside the app regardless of your system language.
Safe login, flexible start
Start instantly as a guest without an account, and switch anytime to an Apple or Google account without losing your data.
Open TimeOn now and bring the people you check most often into one calendar. When scattered plans come together in one line, time becomes something you create together, not something you just manage.
