Some days are still far away. Luna brings them close enough to feel now. Your calendar remembers the date. It doesn't remember why it matters. The trip you've waited six months for sits in the same gray box as a dentist appointment — until it sneaks up on you. Luna Days takes the moments that matter out of the grid and puts them where you'll actually see them. COUNT DOWN TO WHAT'S COMING Birthdays, weddings, vacations, a due date, the first day of school. Give each one a color, an emoji, and a photo. Watch it come closer at a glance in the morning and on a widget between messages — and when the day arrives, Luna makes it feel different. COUNT UP FROM WHAT YOU'VE KEPT Some days aren't getting closer — they're becoming part of who you are. Sober days, a running streak, days since you started something hard. Luna counts them up and marks the milestones: 30, 60, 90, 100, 365 and beyond. Nobody claps for day 100. Luna does. BIRTHDAYS WITHOUT THE MATH Enter someone's age instead of their birth year and Luna works out the rest — "34" today becomes "Turns 35" on the day. Don't know the year at all? The birthday still works. MADE TO BE GLANCED AT - Home Screen widgets: one countdown, your next three, or a compact list - Lock Screen widgets, including a ring that fills in real time - A Live Activity that follows the final day down to the second - A Calendar Countdown widget that follows a calendar you pick — nothing to import - Apple Watch app and complications - Siri: "Hey Siri, days until Trip to Japan in Luna" - A real iPad layout — three panes, not a stretched phone app ORGANIZED AROUND YOUR LIFE A birthday can be Birthdays and Family at once, so one tap shows a whole side of your life. Filter by tag, search everything, and choose the view that suits you: list, compact, grid, or calendar. See a month as a wall of days, or a whole year at once. EFFORTLESS TO SET UP Pull birthdays straight from Contacts and events from Calendar — no retyping, and nothing in your calendar is changed. Name something and Luna suggests the emoji and color itself. PRIVATE BY DESIGN No account. No ads. No analytics. Nothing collected. Luna has no analytics and no servers of ours — nothing about you is ever sent anywhere. Your countdowns live on your devices and sync through your own private iCloud, which the developer cannot read. Luna Days is free. Start with the next thing you're looking forward to.
