The problem with time estimates is that we always get them wrong — and knowing that isn’t enough to fix the bias. We estimate the task in isolation, ignoring everything else on our plate. We underestimate to look efficient. And we do it all again the next week.
The Adaptive Time Tracker measures the gap between what you estimate and what it actually takes. It learns. It automatically corrects your next estimates.
How it works
6 task categories: development, design, research, production, meeting, admin.
For each category, the tool computes a correction coefficient based on your last 10 completed tasks. If you consistently underestimate dev tasks by ×1.8, it knows — and pre-corrects your next estimates accordingly.
The timer is timestamp-based (not a counter): it works even when your screen is off or the tab is in the background. Mobile-safe by design.
The weekly capacity bar (70% of your declared capacity — 30% reserved for the unexpected) shows you in real time whether you’re overloading your week before you even start.
Phase 2 — Shipped features
- Week view: 7-day grid with category-colored load bars and capacity heatmap
- Stats dashboard: time per category, average coefficient, estimation accuracy %
- History: automatic archive of past weeks before reset
- Drag & drop: reorder active tasks manually
- FloatingTimer: persistent widget when you navigate to other tabs
- Delete task: also removes the learned coefficient if the task was completed
Phase 3 — Coming soon
User profile, multi-device cloud sync, Notion integrations, automatic weekly reports. Potentially packaged into a Productivity OS mobile app.
