From the year to the day, without losing your place.
Year, month and day open one inside another, with no tabs or menus: tap a month to go in; tap a day to see its agenda; swipe from the edge to go back, and everything stays where you left it. Each view is a continuous scroll, and "Today" brings you back to the present.

Year
All twelve months at a glance; tap one to open it. Each year carries its own title and scrolls away with the calendar, like a page.

Month
Continuous scroll, month after month; tap a day to see its agenda. Days with something on them take the colour of their event.

Day
Your agenda in continuous scroll, forwards and backwards, no arrows. With the time, the place and each event's colour stripe.
Fact of the day
18
October
Louis XIV revokes the Edict of Nantes
In 1685, France outlawed Protestantism and drove hundreds of thousands of people into exile.
Every day, one fact for the date.
Written calmly, with its year and category, and a link to Wikipedia to keep reading.
- One for every day of the year, February 29 included.
- In your language: all nine in the app.
- A quiet nudge every day, at the time you choose, if you turn it on. And the first time you open the app each day, the fact greets you.
Eleven looks. Two free, nine with Plus.
Each with its own base and ink, made to read well by day and by night. Switch with a tap, and the widgets follow.












On the calendar you already use, in your colour.
Marrow uses your iPhone's calendar: what you add shows up in your other apps and travels through your iCloud.
- Create and edit with repeats (daily, weekly, every two weeks, monthly or yearly), alerts, location search through Apple Maps, notes and a link.
- Alerts that arrive: Marrow schedules its own (with your notification permission), even when Calendar's are off.
- A live countdown on the page of every event that hasn't happened yet.
- A colour per event, so you can tell work from the weekend at a glance.
- Search by title, place or notes, accent- and case-insensitive.
Four colours free, eleven more with Plus.
A live countdown, in your look.
Pick an event and see how long is left — in days, hours, minutes and seconds — on your Home and Lock Screens. Every widget dresses in the look you chose. With Marrow Plus.






Nine languages, yours among them.
The app, the widgets, the alerts and each day's fact, in the language you choose. By default it follows your iPhone's.
The app is complete. Plus makes it yours.
