## What is Kurun?

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).

### 5/5 — 개선 부탁드려요

*2026-08-15*

24시간 원형 그래프 UI 너무 직관적이라서 잘 쓰고 있어요.

그런데 버그가 너무 많아서 불편해요. 터치도 안되고요, 카테고리 순서 변경도 안되고요, 변수명 바꾸는 것도 안되네요..

또 미분류 카테고리는 왜 이름을 바꿀 수 없게 설계하신 거죠? ㅠ.ㅠ

**Developer response:** 안녕하세요. 앱을 이용해 주시고 소중한 리뷰를 남겨 주셔서 감사합니다. 24시간 원형 그래프 UI를 잘 사용하고 계시다니 기쁩니다.
말씀해 주신 오류로 불편을 드려 죄송합니다. 터치, 카테고리 순서 및 변수명 변경, ‘미분류’ 카테고리 이름 변경 문제는 다음 업데이트에서 수정할 예정입니다.
업데이트 후에도 문제가 있거나 불편한 점이 있으시면 앱 내 ‘문의하기’를 통해 알려주세요. 더 안정적이고 편리한 앱이 되도록 계속 개선하겠습니다. 감사합니다.

### 5/5 — 안녕하세요

*2026-05-20*

직관적으로 하루를 기록할 수 있어서 너무 좋아요. 깔끔하고 군더더기 없어요.
다만, 아애패드랑 아이폰에 설치해서 동시에 쓰고 싶은데, 구독은 연동이 되는데 데이터는 연동이 안되는 것 같아요. 맞나요?ㅠ 
핸드폰 따로, 아이패드 따로 기록해야하나요?

**Developer response:** 소중한 리뷰와 귀한 의견을 남겨주셔서 진심으로 감사드립니다.
직관적으로 기록할 수 있는 점을 좋게 봐주셔서 큰 힘이 됩니다.
현재 본 앱은 iPhone에서 다른 iPhone으로 기기를 변경할 경우 데이터가 이어지도록 지원하고 있으나, iPhone과 iPad 간 기록의 실시간 동기화는 아직 지원하지 않고 있습니다.
이용에 불편을 드려 죄송합니다. 보내주신 의견을 참고하여, 앞으로는 iPhone과 iPad 간에도 원활하게 동기화할 수 있도록 개선을 검토해 나가겠습니다.
앞으로도 더욱 사용하기 편한 앱이 될 수 있도록 꾸준히 개선하겠습니다. 감사합니다.

**Developer response:** 안녕하세요! 저희 앱을 이용해 주시고 좋은 리뷰까지 남겨주셔서 진심으로 감사드립니다.
