What’s coming.
A trip. A due date. A first day of school. The moon fills as the day nears, and the last day counts to the second.

Count up
What’s kept.
A streak. A new job. Day one of anything. Luna marks nine milestones, from day 30 to day 1,000.
A closer look
See it in Luna.
The days that matter, the math you shouldn’t have to do, and the screens you already check.
-
See it coming.
A date 68 days out stops being a line in a calendar. On the final day it counts to the second.
-
Then it’s here.
Today. Ten years. Tonight the moon is full.
-
You know her age. Luna does the math.
Turns 80. Type an age — no birth year required.
-
Nobody claps for day 100. Luna does.
Nine milestones, from day 30 to day 1,000. This one is a full year.
-
One glance is enough.
Lock Screen, Dynamic Island, Home Screen, Apple Watch. Your next day is already on the screen.

Give it a date.
Type a title and Luna proposes an emoji and a color. One tap to accept.

Today first.
Then everything you’re waiting for.
What’s today sits on top. What you’ve pinned stays close. Everything else lines up by how soon it arrives — and the days you’re counting up keep their own place.

Quiet stretches and crowded seasons, visible before they arrive.
Private by design
Your dates are nobody else’s business.
No account to make. Nothing to opt out of. There are no servers of ours and no analytics, so nothing about you is ever sent to us.
Data Not Collected
That’s the App Store privacy label, in full. No ads, no analytics, no tracking, no telemetry.
Your private iCloud
Your devices stay in step through your own iCloud account. Luna’s developer cannot read what’s in it.
On-device intelligence
Emoji and color suggestions run on your iPhone. Contacts are read to find birthdays, never modified. Zero third-party code.
Luna Days
And so much more.
FAQ
Questions, answered.
How do I add a day?
Tap plus. Give it a title and a date, then choose whether it counts down to that day or up from it. Luna suggests an emoji and a color as you type — take them or pick your own.
Count down or count up?
A countdown is the days until something: a trip, a due date, a launch. A count-up is the days since something started: a sobriety date, a streak, a new job. Count-ups mark 30, 60, 90, 100, 180, 250, 365, 500, and 1,000 days.
Birthdays without a year?
Yes. Enter an age — “79” — and the birthday reads “Turns 80.” Blank is fine when you don’t know the year.
How do I add a widget?
Touch and hold your Home Screen, tap plus, and search for Luna. On the Lock Screen, touch and hold, tap Customize, then add a widget above or below the clock. Every widget can pin one countdown, follow tags, or show whatever’s next.
Can a widget show only birthdays?
Yes. Long-press the widget, tap Edit Widget, and point it at the Birthdays tag — or any tag you keep. The rest of the list stays out of that rectangle.
What about compact tags?
Settings → Compact tag chips. The filter bar becomes a row of emoji, same order, less width. Turn it off and the names come back.
Is it private?
The App Store label is “Data Not Collected,” and that is literal: no account, no ads, no analytics, no servers of ours. Sync is through your own private iCloud. Luna’s developer cannot read it.
Which devices?
iPhone and iPad running iOS 17 or later, and Apple Watch running watchOS 10 or later. There is no Mac, web, or Android version.
