Do you work changing shifts? Keep your roster, work hours and family planning together with Time Calculator.

A shared calendar helps you coordinate appointments. TC Pro adds reusable shift definitions, work-time calculations, earnings estimates and a personal dashboard in the same app. Choose calendars already available on your Android device and bring them into your planning.

Start free with time calculations. Unlock the planning and extra tools below with one optional Pro purchase, with no subscription. Use Pro on your compatible Android devices with the same Google Play account used for your purchase.

PRO: SET UP YOUR SHIFTS ONCE, USE THEM AGAIN
Save your own shifts with start and end times, breaks, multiple time blocks and recognisable colours. Use repeating patterns and create, import, export or share shift libraries. Reuse your definitions when building your roster instead of entering the same shift details each time.

Combine work, leave and time off in lieu on one day: for example, 6h36 of work and 1h of leave. Review separate totals by week, month or year and export to Excel or CSV.

PRO: SEE HOW YOUR PLANS FIT TOGETHER
Compare your roster with selected calendars for your partner, family, work or school. Use month and week views, with appointments grouped by calendar in the day details. Choose background and text colours, add day notes and optional shift reminders.

Sharing and synchronisation stay with your calendar provider. Calendars must be available on your Android device with the appropriate access. External appointments can open in your calendar app.

PRO: TURN WORKED TIME INTO USEFUL FIGURES
Measure working time or enter a workday manually. Include breaks, your entered rates and supplements to calculate work hours and estimated earnings. Review your work history without switching to a separate time calculator for every entry. Estimates depend on your input; TC does not determine statutory pay or automatically calculate remaining leave entitlement.

PRO: YOUR OVERVIEW, ON YOUR TERMS
Arrange dashboard cards in your preferred order and choose your quick actions. See this month's appointments and important dates in a compact list. Use all six home-screen widgets, including planning and shared-calendar views, to consult key information without opening the full app.

PRO: REMEMBER THE DATES THAT MATTER
Keep birthdays, anniversaries and other occasions with icons, reminders and countdowns. See the elapsed time today and the next occurrence. Import supported CSV or ICS files with a preview, selection and possible-duplicate warnings. Publishing to your calendar is optional.

MORE TOOLS INCLUDED WITH PRO
• Full saved calculation history and favourite calculations.
• Chronometer with laps and sessions, plus a timer.
• World clocks, a meeting planner across time zones and date differences.

• Backup and restore, with optional automatic backups.

TRY TIME CALCULATIONS FOR FREE
Add, subtract, multiply and divide durations in days, hours, minutes and seconds. Switch between time and decimal input, or use the regular calculator. Each calculator mode keeps the last five calculations. Two of the six widgets are included for free.

NO ADS. NO TC ACCOUNT. NO SUBSCRIPTION.
Twenty app languages. Core calculations and local planning work offline. Purchases, updates and external calendar or cloud services need connectivity. Reminders depend on Android permissions and battery settings.

Your calculations and planning are not sent to a Tempo Apps Studio server. You choose calendar, backup and sharing destinations; those services have their own settings and privacy practices. The privacy policy explains data use and deletion.

Explore the free calculator and choose Pro if you want your shifts, hours and everyday time tools together.
