The year passes faster than we notice. Days Left turns it into something you can see, and the moments inside it, into something you can count down to. Whether you are tracking a trip, a birthday, or just trying to stay aware of how the year is moving, Days Left keeps it in front of you. Quiet. Beautiful. On every home screen. YOUR YEAR AS 365 DOTS - See the whole year at a glance, with each day a single dot. - Days lived fill up; days ahead stay open. Today is highlighted. - Three home layouts to choose from: Editorial, Centered, and Weeks. - Refreshes automatically at midnight, so what you see is always honest. COUNT DOWN TO WHAT MATTERS - Add events with a title, a date, and an icon you pick from a curated set. - Birthdays, trips, anniversaries, deadlines, holidays, marathons, or anything else. - Each event shows the days left, percent passed, and a dot-grid progress meter. - Optional reminders fire the day before, so important dates do not slip by. HOME AND LOCK SCREEN WIDGETS - 11 year-progress widgets in small, medium, and large sizes. - 7 event countdown widgets in small, medium, and large sizes. - Lock screen widgets: circular, rectangular, and inline. - Every widget reflows with your chosen color theme. MAKE IT YOURS - Eight accent themes: Classic, Electric Blue, Neon Mint, Purple Dream, Sunset Glow, Amber Fire, Crimson, and Ice. - Adaptive across light and dark mode, so contrast stays right either way. - Your accent reflows everywhere: home, events, widgets, paywall. PRIVATE BY DESIGN - Your events live on your device. No server, no account, no sign-in. - No tracking. No analytics. No third-party data sharing. - Reminders are scheduled locally on your iPhone, never routed through us. - The widget extension reads from a shared on-device store, nothing more. HOW TO USE 1. Open Days Left and watch the year fill in as 365 dots. 2. Tap the plus button on the home screen to add your first event. 3. Long-press your home screen, tap plus, and search "Days Left" to add a widget. 4. Open Settings to pick a color theme that feels like you. 5. Turn on a reminder for an event so the day before lands gently in your notifications. Stop letting the days blur. See them, count them, and make every one of them count. Free to download. Some features require a premium purchase. Privacy Policy: https://estifie.com/apps/daysleft/privacy-policy Terms of Use: https://estifie.com/apps/daysleft/terms-of-use

일정과 할 일을, 달력 한 장에. 코그 일정은 iPhone의 캘린더와 미리 알림을 그대로 씁니다. 따로 옮겨 적을 필요 없이 쓰던 일정과 할 일이 한 달력 안에 나란히 놓이고, 여기서 만든 항목은 캘린더 앱·미리 알림 앱에도 그대로 남습니다. 날짜 칸에는 제목이 글자로 적힙니다. 점이나 숫자로 줄이지 않아 달을 넘기며 훑어도 그날 무엇이 있는지 바로 읽힙니다. "다음 주 화요일 3시 반 기획 회의"처럼 한 문장으로 적으면 날짜와 시간, 반복까지 읽어 채워 줍니다. 문장을 읽는 일은 기기 안에서 끝납니다. 개발자가 운영하는 서버가 없습니다. 일정과 할 일은 Apple의 iCloud를 통해 같은 Apple 계정의 내 기기끼리만 오갑니다. [주요 기능] • 일정과 할 일을 한 달력에 • iPhone 캘린더·미리 알림을 원본 그대로 사용 • 한 문장으로 적는 입력 (채팅·음성) • 지남 · 오늘 · 예정 · 언제든, 네 칸의 할 일 • 음력 표시와 음력 반복 • 위젯 여섯 가지와 잠금 화면 위젯 • 아침 브리핑 · 지난 할 일 알림 · 배지 • iPad에서는 왼쪽 달력, 오른쪽 그날 목록 • 색상 테마와 앱 아이콘 일곱 가지 • 한국어 · English · 日本語 채팅과 음성으로 적는 한 문장 입력과 시각·캘린더 추천, AI 입력 위젯, 색상 테마와 앱 아이콘은 코그 일정 Pro에서 쓸 수 있습니다. 코그 일정 Pro는 한 번 구입하면 계속 쓰는 앱 내 구입입니다. iOS 26 이상의 iPhone과 iPad에서 동작합니다. 문장 해석은 Apple Intelligence를 지원하는 기기에서 가장 정확하고, 지원하지 않는 기기에서도 쓸 수 있지만 정확도가 낮습니다.
