Time Calculator

Make time for what matters. Time Calculator brings time calculations, shift planning and everyday time tools together in one ad-free app. Start with free time calculations. Choose the optional one-time Pro upgrade for planning, reports and the full set of time tools. No subscription. FREE: EVERYDAY TIME CALCULATIONS Add, subtract, multiply and divide durations in days, hours, minutes and seconds. Switch between time and decimal input and revisit your last five calculations. The standard calculator and two of the six widgets are also free. PRO: SCIENTIFIC AND GRAPHING CALCULATOR Switch between the simple calculator and Graph / science PRO. Work with fractions, durations, trigonometry and complex numbers. Plot functions, polar curves, parametric curves and recursive sequences. Use tables, numerical analysis, statistics, regressions, matrices, finance and local formula scripts. Save formulas and calculations. The new calculation features work offline. PRO: PLAN YOUR WORK AND YOUR DAY Create colour-coded shifts with breaks, multiple time blocks and repeating patterns. See your planning by month or week and view the selected day's details below your own month calendar. Keep notes with optional reminders and jump back to today. Combine work, leave and time off in lieu on one date. Review totals by week, month or year and export to Excel or CSV. PRO: YOUR CALENDARS, TOGETHER Choose which linked calendars to show together, such as work, family and school. Calendar widgets highlight today and indicate extra items with +N. Tap a date to open its details. Linked calendars must be available on your Android device; sharing and synchronisation remain managed by your calendar provider. External appointments can be opened in your calendar app. PRO: MORE THAN A PLANNER - A personal dashboard with relevant upcoming information. - Work-hour calculations and earnings estimates using your entered rates and supplements. - A chronometer with laps and sessions, plus a timer with a large scrolling duration picker. - World time, travel calculations and a visual meeting planner across time zones. - Date differences and important dates with countdowns, reminders and optional agenda visibility. - Full saved calculation history, favourites and all six widgets. PRO: KEEP AND SHARE YOUR INFORMATION Create backups and restore your data. Export or share supported information as Word, Excel, CSV, PDF, PNG or ICS. Available formats depend on the feature. Export reports are not a substitute for a restorable backup. MADE FOR EVERYDAY USE No advertisements. No Time Calculator account required. Available in 20 app languages. Choose your display preferences and Home-button destination. Core calculations and locally stored planning work offline; purchases, updates and external calendar or cloud services need connectivity. Data is stored locally. If you link calendars or use backup and sharing services, their own account, storage and synchronisation settings apply. You choose whether to publish an important date to your linked calendar. Reminder delivery also depends on Android permissions and battery settings. ONE PURCHASE, LIFETIME PRO Free and Pro are clearly separated in the app. Pro is an optional one-time lifetime purchase, with no recurring payment. Hours and earnings are based on your entries. The app does not determine statutory pay entitlements or an automatic remaining leave balance. Scientific results are numerical approximations. Not a TI emulator; TI programs and apps are not supported.
