Read full description

Chronicle - Time Journal is a private, local-first planner and time journal for building a realistic day, tracking what actually happened, and reviewing patterns over time. Use Chronicle to plan tasks and activities with descriptions, colors, expected durations, dates, recurrence, and tags. Work from My Day when you want a focused view of a selected date, then use the visual Timeline to record actual time with start/stop tracking, manual interval creation, editing, deletion, and task assignment. Review your tracked time with Statistics. Chronicle shows daily and custom-range summaries, task totals, tag breakdowns, and recorded intervals so you can compare the shape of your plan with how the day actually went. The free version includes: - Task and activity planning - My Day date-focused execution - Visual Timeline time tracking - Manual interval editing and task assignment - Tags and tag hierarchy - Tracked-time Statistics - Supported local reminders for task and running-interval workflows - Day-boundary settings - On-device export, import, and reset tools - First-run guidance and in-app tips Optional in-app purchase: Calendar Integration unlocks selected device calendars as read-only overlays on Timeline. Calendar access is optional, processed on device, and used only when you enable it. The app includes a one-month free trial for this feature, followed by a lifetime purchase if you want to keep using it. Privacy is central to Chronicle. Your tasks, time records, tags, statistics, reminder settings, and Calendar overlay selections are stored and processed on your device. No account or sign-in is required. The developer does not collect, sell, share, track, or use your personal app content for advertising or profiling. Chronicle is for people who want a practical record of the day: what they planned, what they did, and what patterns they can learn from.
