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.
