Time Calculator

Bring your time, work and planning together. Time Calculator combines time calculations, shift planning and everyday time tools in one ad-free app.

Start free with time calculations and a regular calculator. The optional Pro upgrade is a one-time purchase, with no subscription.

FREE TIME CALCULATIONS
Add, subtract, multiply and divide durations in days, hours, minutes and seconds. Switch between time and decimal input. Use the regular calculator for everyday arithmetic. Each calculator mode keeps your last five calculations for free. Includes two of the six widgets.

PRO: SHIFTS IN YOUR STYLE
Plan by month or week with custom shifts, breaks, multiple time blocks and repeating patterns. Choose background and text colours separately. Save your own colours and reuse them from a compact palette. Add notes and optional reminders.

Combine work, leave and time off in lieu on the same day, down to the minute. For example, split 7h36 into 6h36 work and 1h leave. Review separate totals by week, month or year and export to Excel or CSV.

PRO: YOUR CALENDARS, TOGETHER
Choose linked calendars such as work, family and school. Both My calendar and Shared calendar group the selected day's appointments by calendar. Empty groups stay hidden.

Appointment cards follow available original background and text colours. Personalise their appearance on your own device if you prefer. Events without their own colours use the app's default style. Calendar widgets highlight today and show extra items with +N.

Calendars must be available on your Android device. Sharing and synchronisation are handled by your calendar provider. Open external appointments in your calendar app.

PRO: WORK HOURS AND EARNINGS
Measure your working time or enter a day manually. Start, end and break are directly accessible; expand rates and supplements when needed. Review your work-hour history and estimates based on your entries.

PRO: IMPORTANT DATES
Keep birthdays, anniversaries and other moments with familiar icons, colours and countdowns. Import supported CSV and ICS files, preview their contents and select which dates to add. Possible duplicates are flagged. Supported ICS reminders are imported only if you choose. See elapsed time up to today and the next occurrence. Publishing dates to your calendar is optional.

PRO: YOUR TIME TOOLS
- Personal dashboard with reorderable cards, configurable quick actions and a compact monthly list of appointments and important dates.
- Chronometer with laps and sessions, plus a timer with a scrolling duration picker.
- World clocks and a meeting planner across time zones.
- Calculate arrival or travel duration from entered times; not a route planner.
- Date differences, full saved calculation history and all six widgets.
- Backups and restore; share or export as Word, Excel, CSV, PDF, PNG or ICS, depending on the feature. Reports are not a substitute for a restorable backup.

MADE FOR EVERYDAY USE
No advertisements and no Time Calculator account required. Twenty app languages, display preferences and a configurable Home button. Core calculations and local planning work offline. Purchases, updates and external calendar or cloud services need connectivity.

Data is stored locally. Linked calendars, backups and shared files also depend on the settings of your chosen services. Reminders depend on Android permissions and battery settings.

Pro is an optional one-time lifetime purchase with no recurring payment. The app does not determine statutory pay entitlements or an automatic remaining leave balance.
