What's New in Time & Date Calculator ++

45

September 18, 2026

Thank you for using Time & Date and for bringing such care to the hours, dates, and schedules you manage. This update rewards that attention with cleaner Time Column charts, broader sharing choices, safer transfers, and more predictable record handling. CLEARER TIME COLUMN CHARTS - The four Time Column calculators can now turn their saved entries into line, bar, or scatter charts. - Charts show entries only, so there are no confusing Input, Output, Pending, or Total series mixed into the view. - Entry 1, Entry 2, and later labels stay in a consistent left-to-right order. - The chart title now fits compact iPhone screens without being cut off. - Visible horizontal-axis ticks and an Entries title make the sequence easier to follow. - Duration labels use compact time values that are easier to read at a glance. - Line and scatter points receive useful space around their value range instead of touching the chart corners. - Bar charts keep a zero baseline so the relative sizes remain honest and easy to compare. - Longer entry lists retain horizontal scrolling instead of compressing labels into an unreadable row. MORE WAYS TO SHARE YOUR WORK - Calculator share menus now include a PDF choice for the information currently on screen. - Time Column charts can produce a PDF with their entries in the same clear order. - Tracked dates and saved History records also support PDF export. - History continues to offer JSON export for backup and CSV export for spreadsheet work. SAFER HISTORY IMPORT AND EXPORT - History import and export handle up to 10,000 records per transfer. - JSON imports keep an explicit 100 MB safety ceiling before the archive is loaded. - Imports add records only when the same saved data is not already present. - Matching records are skipped instead of creating unnecessary duplicates. - Transfer work runs away from scrolling and editing, then confirms completion with a brief message. - Empty or unusable transfers now provide a finished result instead of leaving you waiting. A CLEANER, LIGHTER HISTORY - History keeps names, dates, calculator sources, and useful text details without saving calculator images. - Existing images are not displayed, exported, or carried into newly saved records. - Opening an older record removes only its leftover image while preserving the text information you saved. - Records load in efficient batches as you scroll, with no extra button to press. - Record-name and proper-noun fields no longer try to correct the spelling you intended. BETTER RECORD AND IPAD BEHAVIOR - Adding a tracked date now creates a minimal saved record right away, so closing the screen does not silently discard it. - Valid changes save as you work, while deletion remains a decision you make from the dates list. - On iPad, master and detail navigation stays visible with a useful placeholder before you select a record. MORE CONTROL IN SETTINGS - Reset All Data now provides a direct way to clear the app's saved database. - A strong confirmation explains that the action is unrecoverable before anything is removed. - Deletion runs without freezing the interface and finishes with a confirmation message. This release also improves keyboard-aware forms, compact-screen layouts, accessibility descriptions, and menu icons. The result is a steadier experience whether you are totaling a shift, reviewing time entries, tracking a date, preparing a PDF, or moving saved calculations to another device. Thank you again for using Time & Date with such thoughtful attention. Your careful work deserves clear tools, and this update gives you a more readable, controlled, and dependable way to calculate, review, share, and keep the details that matter.
