Kurun turns your entire day into a single pie chart — so you can see exactly where your time goes, without scrolling through endless lists. Why a pie chart? Most calendar and to-do apps stack your schedule top to bottom. But a vertical list can't show you the full picture. Kurun fits all 24 hours into one circle. The moment you look at it, you just get it: - That "quick" social media check? It's a surprisingly big slice. - Gaps in your day show up as empty space — no hiding from lost time. - More time resting than working? The imbalance is obvious at a glance. Before you analyze the numbers, you feel the shape of your day. That's the power of the circle. Does this sound familiar? - You were busy all day, but nothing feels done - You can't quite remember how you spent the last 24 hours - You have no idea how much time you lose to scrolling or breaks - You want better balance between work, study, and sleep - You know something's off, but don't know where to start What you can do with Kurun - Visualize your full 24 hours in one pie chart - Color-code activities and tasks for instant clarity - Spot untracked gaps in your day at a glance - Create custom categories — study, work, sleep, anything - Review each day and catch time imbalances early - Organize your tasks with the built-in to-do list - Use the built-in stopwatch and timer to log time directly to your timeline Perfect for - Anyone building better time management habits - Students tracking study sessions and focus time - Professionals looking to improve work-life balance - Fans of time tracking, life logging, or habit journaling - Anyone who prefers visual records over written notes Log it simply. See it clearly. Feel how you spend your time — with Kurun. Some features (To-Do, Pomodoro Timer, and more) are available with a Pro plan (in-app purchase).
