Kurun turns your entire day into a single pie chart โ€” 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 โ€” 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 โ€” 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 โ€” with Kurun. Some features (To-Do, Pomodoro Timer, and more) are available with a Pro plan (in-app purchase).

About

Day Mark

Features
Read full description

Day Mark is a to-do app that remembers what you finished. โ€ข Calendar heatmap: see what you did on any day at a glance. Color only shows how much got done โ€” it's a ruler, not a medal. No streaks, no scores. โ€ข Lead time: every task shows how long it took from creation to completion. โ€ข Journal: write a few lines about a day and read them next to what you finished. โ€ข To Do: one list, sorted into today, later and no date. Mark what matters as a priority and it moves to the top. No folders to manage. โ€ข Focus: Pomodoro or stopwatch, with an optional soundscape (rain, tide, a distant bell) and a soft ticking clock, all synthesized on the device. โ€ข Your data stays yours: syncs across iPhone, iPad and Mac through your own iCloud, and the app keeps a readable Markdown/JSON archive you can copy from the Files app. โ€ข No servers, no sign-up, no ads, no tracking.
