"Am I on days or nights tomorrow?"
If you work shifts, you ask this every day. OneTwoDay answers it for you.

Pick your company and team, and every upcoming shift fills your calendar.
Or snap a photo of your roster — AI reads it and builds it for you.
No account, no complicated setup.

■ Your schedule in 3 seconds
· Search your company — if it's registered, just pick your team
· Photo or Excel — upload the roster you were given and AI reads it
· Request registration — send a photo or Excel file and an operator registers your roster
· Enter it yourself — tap a common pattern like Day-Day-Night-Night-Off-Off
No company roster? No problem. Tap a pattern and you're done.

■ Today's shift, right on your phone
Home screen and lock screen widgets show today, today + tomorrow, this week, this month and shift swaps — no need to open the app.

■ Right on your wrist — Galaxy Watch
Check today's shift and how far along it is, plus tomorrow and this week, in the app for Galaxy Watch and other Wear OS watches.
When you finish, just tap «Done» on your watch. It shows the schedule your phone sends, so there's nothing extra to set up.

■ «Mark shift done» when you finish
Tap «Mark shift done» after work to see a «Good work today» card and which shift of the month it was.
If you've set up pay, it also shows about how much you earned today — and you can tap it right on the Today home screen widget.

■ A heads-up the night before
· "Tomorrow: Night · starts 19:00" — at the time you choose
· Another reminder a few hours before your shift
· Only on days your shift changes, or only for nights
Reminders follow local time wherever you are.

■ Everyone gets 3 days off. How many do you get?
Korean public holidays — including Seollal, Chuseok and substitute holidays — show in red,
and on long weekends you see exactly which of those days you're actually off.
Newly announced holidays appear without an app update.

■ Use your leave right here
See exactly which days to spend 1–3 days of leave on for the longest break.
Choose whether to skip night shifts or join weekends.

■ Rotation duty and weekday rosters, handled
For rotation rosters, pick your group (A–D) and only your rotation days show as work.
Day shifts that are off on weekends and holidays, and weekday duty rosters that skip them, line up too.

■ Shift swaps, out of the group chat
Post the date you want to swap. Coworkers on the same team see it right away, and you're both notified when it's agreed.

■ Match days off with friends and family
Share your schedule with one link and see your shared days off at a glance.

■ Also included
· Shift stats — nights and work days this month
· Notes on any date, one-off changes, overtime and on-call
· Set which codes count as days off (like "~" or "O")
· Phone calendar sync — shifts, notes and events in your phone's calendar too
· 16 screen themes — day and night themes follow your device's dark mode
· Dark mode · 한국어 / English / 日本語 / Tiếng Việt
