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).

Okay, real talk: where does the time go? You sit down for "five minutes," look up, and somehow it's dark out. You know you've got stuff to do — you just can't feel how much time is left, or which thing to start first. When your brain doesn't do time, a to-do list won't save you. It's just more stuff to lose track of. Ringround shows your whole day as a circle you can actually see. Your day becomes a 24-hour dial. NOW sits at the top, the day turns underneath, and one glance tells you where you are and how long until the next thing. Time stops being invisible. What it does: • See your day at a glance — colorful blocks on a ring, not a wall of text. • Can't pick what to do? Hit Ring Round — give the dial a spin and let it choose for you. Decision made, no spiral. • Put your day on your Lock Screen and in the Dynamic Island — a calm cylinder fills with color so you can check the time without falling into your phone. • Gentle nudges before things start. Optional. Never shouty. • Your colors, your categories, your names for things. Make it yours. Made for brains that lose time. ADHD, autistic, AuDHD, time-blind, or just perpetually "five minutes behind" — this one's for you. Ringround doesn't try to fix you or optimize you. You're not a productivity project. It just makes time something you can see, so the day stops slipping out from under you. No accounts. No ads. No subscriptions or upsells nagging you forever. Nothing ever leaves your phone. Your day's right there. It's a circle. Go take a look.
