What's New in Time & Date Calculator ++

41

July 21, 2026

Thank you for using the Time & Date Calculator app and pushing it toward the kind of tool people can trust for real work. This update is focused on clearer screens, fewer duplicate controls, better calculator labels, and faster access to the tools you use most. This update brings a major refresh to the way the app handles everyday time math, date tracking, work-hour calculations, and Pro workflows. The goal is simple: make the tools easier to find, easier to trust, and faster to use when you are checking real numbers under real pressure. Favorite calculators: - Add frequently used calculators to Favorites - Keep Favorites at the top of the calculator menu - Long press a calculator to favorite or un-favorite it - Reorder favorite calculators with drag and drop - Use the Favorites help button for quick instructions NEW CALENDAR TAB: • Added a calendar view for tracked dates. • Mark saved dates directly on the year calendar. • Long-press marked days to inspect saved date details. • View the selected day in Christian, Hebrew, and astrology calendar systems. • Turn calendar systems on or off in Settings. • Fixed year display so calendar years never show commas. • Added saved-date counts and marked-day counts. IMPROVED APP NAVIGATION: • Updated the first tab to Calcs for a shorter, cleaner label. • Renamed the calendar tab to Cal. • Kept Dates, Cal, and More separated from the calculator list. • Reduced tab label crowding on smaller phones. • Cleaned up sheet controls in Settings. TRACKED DATE IMPORT AND EXPORT: • Import replaces the current tracked-date list. • Export creates a shareable tracked-date file. • Import and export are now Pro features. MORE PRO VALUE: • Tracked Dates now supports a free daily date before Pro is required. • Free users can add 1 tracked date per day. • Pro unlocks heavier date-tracking workflows. SETTINGS UPDATES: • Improved Settings layout. • Calendar source toggles now explain what they control. • Hid internal product identifiers from the Pro Status section. • Kept purchase restore and status controls visible. • Added tracked-date import and export controls. • Improved feedback after successful imports. TIME AND DATE READABILITY: • Date-distance rows now avoid unnecessary hour details for older or farther-away dates. • Saved-date text is easier to read when the date is months or years away. • Time-of-day appears only when it helps. • Calendar summary numbers are cleaner. WORKFLOW POLISH: • Added edit support for tracked dates. • Editing preserves the existing saved date record instead of creating a duplicate. • Add Date and Edit Date now share the same familiar form. • The form pre-fills values when editing. • Save replaces Add when editing an existing date. UNDER-THE-HOOD IMPROVEMENTS: • Tracked dates are backed by the app's persistent storage. • Calendar markings refresh from saved date records. • Import, export, add, edit, and delete use the same tracked-date store. This release is especially useful for anyone who tracks deadlines, anniversaries, payroll dates, shift schedules, project dates, historical dates, aviation timing, or work-hour records. The app is still fast, direct, and practical, but now the date tools feel much more connected to the rest of the time calculators.
