TaskStack is a next-generation daily task management and life analytics app built with Flutter. Instead of flat to-do lists, TaskStack gives you a living, scrollable 24-hour visual timeline — a real-time view of your entire day that helps you plan with precision, execute with focus, and reflect with data.
Built strictly on Material Design 3, offline-first with SQLite, and powered by multi-horizon analytics.
- Infinite-scroll timeline from 00:00 → 23:59
- Auto-scrolls to current time on launch with a live time indicator
- Task cards sized proportionally to duration and colour-coded by status
- Swipe right to mark done, long-press for context menu
- Create tasks with title, description, purpose, icon, colour, tags, time frame
- Set repeat-within-today tasks (e.g. every 2 hours)
- Daily, weekly, or fully custom recurrence rules
- Intentional completion — tasks are never auto-marked done
- Per-task notifications fired at exactly the right time
- Custom offset: at start, 5 / 10 / 15 / 30 minutes before, or custom
- Deep-links from notification directly into the task
| Horizon | What you see |
|---|---|
| Daily | Hourly activity chart, tag donut, most productive hour |
| Weekly | Day-by-day bar chart, productivity score, tag distribution |
| Monthly | Heat-map calendar, habit streaks, trend line |
| Yearly | GitHub-style 365-day heatmap, year-over-year comparison |
- Light / Dark / System theme
- Custom accent colour
- 12h / 24h time format, configurable week start
- JSON data export & import
