Timebook is a time tracker that records how you spend your day, turns it into habits you can keep, and helps you discover the patterns hidden inside it. No separate check-off: log what you set as a habit, and today's progress fills automatically. Whether you want to build better habits, stay focused on deep work, or fix your sleep schedule, Timebook helps you see what your days really look like — and shape them on purpose. Skip the complicated forms. Start and stop activities with a single tap. The more you log, the better Timebook understands your day - and surfaces insights that lead to better habits. ■ Habits your records keep for you • Today's habits on the home screen — tap a record-based habit to start logging • Set what counts: simply logging it, or a duration, amount, or count goal • Habits tied to a record are judged automatically, with no separate check-off • Streaks and a footprint board show every day you kept • Rest days and skipped days never count as failures ■ Challenges, from 7 days to 100 • Put a window around a habit you already keep: 7, 21, 30, 60, or 100 days • A different badge for each length, and a special trophy when three or more habits started together all succeed • Save and share the result as a badge image ■ One-tap time tracking • Tap a quick-action button to start logging in a second • Watch your current session progress on a circular timer — perfect for Pomodoro-style focus sessions • Edit start and stop times freely • Capture moments with timestamped notes ■ Two ways to revisit your day • Timeline: replay your day moment by moment • Grid: see your whole day as a colorful mosaic ■ Heatmaps that reveal your patterns • Activity frequency by day of week and time of day • Category-level breakdown of where your time goes • A clear picture of what you actually do, hour by hour ■ Routine templates to plan the day ahead • Design your daily plan as a reusable template • Separate templates for weekdays, weekends, and other contexts • Review your routines and see how your days align over time ■ In-depth sleep analysis • Bedtime and wake-time patterns over time • Sleep duration and consistency by day of week ■ More • Dark mode • Available in 13 languages Start tracking with Timebook and become someone who spends time on what matters.
