Good friends. Better timing.
Stop drowning in 200-message group chats just to pick one evening. Intersect hospital rotas, rotating shifts, and 9-to-5 schedules in one tap.
Two Clashing Realities. One Shared Solution.
Why is hanging out with friends so difficult when people work irregular shifts?
Shift Workers & Irregular Schedules
Nurses, doctors, pilots, hospitality, emergency workers
- ✕ Rotating morning, afternoon, and night shifts with changing monthly rosters
- ✕ Post-night recovery sleep and irregular circadian rhythms
- ✕ Unable to commit to static weekly dinners or weekend routines
9-to-5 Regular Workers
Office workers, corporate, static weekly schedule
- ✕ Predictable Monday–Friday schedules with free weekends
- ✕ Plans made days or weeks in advance with little flexibility
- ✕ Never knowing if their shift worker friend is on duty or exhausted

Everything You Need to Know
Common questions about ShiftMate, Free vs Pro plans, and how our overlap engine works.
What makes ShiftMate different from Google Calendar or WhatsApp?
Google Calendar shows individual events, but cannot automatically intersect rotating shift rosters across 10 friends with different circadian sleep hours. WhatsApp requires hundreds of messages to find one date. ShiftMate automatically computes the 4 Golden Slots (Breakfast, Lunch, Aperitivo, Night) where everyone is actually awake and free.
How does the 'One For All' Pro sponsorship work?
If at least ONE member of a group has an active ShiftMate Pro subscription, that entire group becomes a 'Sponsored Premium Crew'. It doesn't count against anyone's 2-group free quota, and everyone in the group gets access to the Telegram bot's AI natural language Q&A!
Can 9-to-5 workers use ShiftMate with their shift worker friends?
Absolutely! 9-to-5 friends configure a fixed weekly baseline once (e.g. work Mon-Fri 09:00-18:00, weekends off) and never have to touch a calendar again. ShiftMate automatically aligns their fixed schedule with their shift worker friends' changing monthly rosters.
How does the AI Rota Scanner work?
With ShiftMate Pro, you can take a picture of a paper roster on your hospital board, or upload a roster PDF, Excel (.xlsx), or CSV file. Gemini 2.5 Flash extracts your shifts, shows you an instant preview, and saves them to your calendar in seconds.
What are Super Hangouts?
Super Hangouts let you combine multiple crews into one big event—like a birthday party with your college crew, work colleagues, and weekend sports friends. Pro users can find Cross-Crew Super Windows and propose the event to all groups simultaneously.
Is ShiftMate available on Android and Web as well as iOS?
Yes! While our visual showcase highlights the native iOS Liquid Glass experience, ShiftMate is 100% native on Android (built with Jetpack Compose & Material 3 Expressive) and available instantly as a modern React 19 WebApp. Everyone in your group stays in sync in real time regardless of what phone, tablet, or computer they use.
