ZenShift is a personal shift calendar for rotating work schedules, day and night shifts, and custom cycles. Set up a pattern once, see your workdays at a glance, and estimate your hours and earnings. PLAN YOUR SHIFTS • View your schedule by month, week, or year. • Add shifts from templates, paint dates with a tap, or remove them with the eraser. • Keep multiple shifts on the same day, including overnight and 24-hour shifts. • Create templates with times, breaks, hourly rates, colors, icons, and reminders. • Repeat two days on/two off, three on/three off, 24 hours on/three days off, or your own cycle. Choose start and end dates, pause a rotation, and recalculate it. • Keep manual shift edits when recalculating a rotation. Template updates apply to shifts that have not started by default; changing past linked shifts requires confirmation. Individual overrides are preserved. WORK AND PERSONAL PLANS TOGETHER • Add meetings, appointments, workouts, birthdays, and trips beside your shifts. • Use timed, all-day, and multi-day events with colors, locations, and notes. • Set daily, weekly, monthly, or yearly repeats and event reminders. • Get a warning when a timed event overlaps a shift. • Remove one occurrence or an entire recurring series. UNDERSTAND YOUR HOURS AND PAY • Track work hours after breaks, night hours, overtime, and extra income. • Set hourly rates for individual shifts and templates, with a default rate as a fallback. • Choose your monthly overtime threshold and night period. • See estimated earnings for completed shifts and the forecast for upcoming shifts. • View reports by week, month, year, or a selected period, with breakdowns by shift type, day, week, and month, plus averages. • Assign missing rates in groups from the report. Add shift notes and reuse extra-income templates. SHARE AND KEEP YOUR SCHEDULE • Customize a PDF with your calendar, summary, breakdowns, and shift details. • Send the file using your phone's sharing options. • Export shifts to a selected device calendar. • Use one account to sync your schedule between iPhone and iPad. • Get shift reminders and review notification history. MAKE IT COMFORTABLE Choose English or Russian, light or dark theme, text size, currency, week start, and 12/24-hour time. Adjust animations and haptic feedback. The basic calendar works locally without a required account. Earnings are estimates based on your entered rates, not payroll payments. Night-time breaks are estimated proportionally because their exact timing is not recorded. Cloud services need an account and internet access. Check the app for ad-removal options and terms. Set up your first template and make your work schedule easier to follow.
