Name alarms; choose personal or one team calendar for alarms, independently of the calendar viewed. WEATHER REMINDERS Home shows weather, shift and alarm. Tap to edit; confirm each change. With consent, ongoing cloud reminders use the last synced area, roster and alarms, including cycles/holidays. Sync changes; forecasts/alerts depend on network, system and permissions. VOICE & TIMING Optional on-device speech reads shifts/available forecasts: Chinese voices, three speeds, preview; off by default. Move automatic alarms 1–180 minutes by weekday/date. Dates take priority; one-time manual edits stay. Guided setup: skip, resume, saved drafts. BUSINESS TEAMS Owners manage people/shifts, review/publish rosters and handle swap, overtime, leave and handover requests. Members view their roster and request free; they set their own alarms, never activated by publication. Plans, hours, leave balances and exports follow permissions, not actual attendance/payroll.

Pro estimates pay by pay period, records received pay and differences, not employer payroll. LIVE ACTIVITIES Pro: ring, large countdown or today's earnings; progress, estimated pay, anniversaries. Choose content/hide amounts. Push refresh depends on network/system. Pay is timestamped, refreshed on opening, not continuous actual income. IMPORT & EXPORT Free Calendar/ICS/image imports; unlimited on-device recognition. Review/match/create shifts and edit dates/times first. Optional Pro cloud recognition requires consent each use: images, including names, employee IDs and rosters, go to CrossShift/recognition providers. Check results.

Local wallpaper on all five tabs or Home only. Original shift colors, saturation, clearer selected dates. Share rosters, each person managing their own; member notes stay local.
