Most time trackers are built for freelancers and billing. Timetracker is built for your whole life. Track everything you do — work, sleep, exercise, cooking, family time, reading — and see how your time is actually distributed across the categories of your life that matter to you. HOW IT WORKS 1. Define your categories — Work, Health, Family, Learning, Leisure, or whatever matters to you 2. Create activities and map them to categories — "Morning run" → Health, "Reading" → Learning + Rest 3. Tap to start tracking. Tap to switch. That's it. 4. Open your dashboard — category breakdown is calculated automatically You do the living. The app does the math. KEY FEATURES • Full 24-hour tracking — not just work hours. Sleep, exercise, commute, cooking, everything counts • Category breakdown — automatic percentage breakdown across your life domains • Hierarchical activities — nest "Work → Meetings → Standups" instead of a flat list • Flexible goals — set minimum, maximum, or exact time targets per day, workday, weekend, or custom schedule • Easy corrections — forgot to switch?

No streaks. Just an honest picture of how you spend your time. FREE TO USE No ads. Unlimited activities and tracking history. Tracking, categories, goals and reports are free.
