Your Apple Calendar, sorted by what matters.

Horizon sorts every event in the calendars you already use into categories, right on your iPhone. Then it puts what matters where you'll see it: your Lock Screen, your widgets, Siri and your wrist.

For iPhone, iPad, iPhone Duo and Apple Watch. Works with iCloud, Google, Exchange and any calendar in Apple Calendar.

Horizon's dashboard: the Today card with the weather and the event happening now, a card with two invitations to answer and four events to categorize, then today's events, each with its category color and icon

Nineteen categories, sorted for you

Horizon knows a dentist appointment from a flight from a birthday dinner, and learns from every change you make. Rename a category, recolor it, turn it off or add your own.

  • Health
  • Travel
  • Birthday
  • Family
  • Social
  • Work
  • Finance
  • Personal
  • Holiday
  • Sports & Fitness
  • Education
  • Entertainment
  • Pets

Features

Every detail, in one place

Open an event and everything about it is on one screen, grouped under clear headings: when and where, who's coming, notes and links, reminders. Change its category from a menu with one tap, and Horizon remembers for next time.

  • Not sure of a category? Horizon's guess sits under the title, with Looks Good and Change
  • Weather for the time and place, and a map that opens in Maps
  • Watch, share or open it in Calendar from the row under the title
Details for Q4 Roadmap Planning Meeting: the Work category button above the title, the date and time, your reply to the invitation, Watch, Share and Calendar buttons, then When & Where with an overlap, a map, the forecast and the calendar

See the shape of your month

Each day in the month view carries a small bar showing the mix of categories on it, so a busy week or a trip stands out before you tap anything.

  • Multi-day events appear on every day they cover
  • The month tucks away to the current week as you scroll
  • On iPad, event titles show right in the day cells
The month view on iPad, with event titles in each day and a category color bar under every date

Turn it sideways for your week

Turn your iPhone sideways in the calendar and the whole week opens, full screen, on an hour grid. Choose a category and its events keep their color while the rest of the week fades to grey, so you see where it fits instead of seeing it alone.

  • Tap an empty hour to add an event there
  • With free time on, open hours show in green, ready to book
  • On iPad, switch between Week and Month in the calendar header
The week view on an iPhone turned sideways, with Work selected: the week's meetings in color with their times, and every other event in grey with only its title

Set a weekly goal, watch it fill

Three workouts a week, or no more than 20 hours of Work. Give a category a goal and Horizon tells you where the week stands, counting what's still on the calendar, so you know whether to plan one more run or say no to one more meeting.

  • At least or at most, counted in events or hours
  • A ring on the category's button fills as the week goes
  • Your daily briefing and Life Patterns track it too
Sports & Fitness selected on the dashboard: its header card with a goal ring and a line saying how many workouts are done and how many are still on the calendar this week

A briefing for today, and for the months behind it

The daily briefing tells you the shape of your day: how many events are left, when you'll be done, and where the free time is. Swipe across to the weekly briefing for the category mix, then to Life Patterns to see where your time has really gone, as far back as a year.

  • Free slots in the daily briefing start a new event in one tap
  • The weekly briefing flags every double booking
  • A Weekly Goals card shows where each goal stands
  • Life Patterns shows when your day happens, what keeps coming back and how full your days run
The daily briefing: good morning, seven events left and done by 9:30 PM, the weather, and today's schedule as a timeline

Count down to the things you're looking forward to

Watch an event and Horizon keeps it in view: a spotlight card for what's happening now or next, a countdown on every card, and a Live Activity on your Lock Screen and in the Dynamic Island for the four hours before it starts, with its category and a bar that fills as it gets closer.

The Watchlist: a spotlight card for the meeting happening now, a suggestion to count down to a Lisbon vacation, then countdowns to a birthday dinner, a concert and a flight

See your free time, then book it

Tap the Free chip and the open time between your events shows right in the list and the month view. Tap a gap and a new event starts there, at the length you like. Type a title and Horizon categorizes it as you type.

  • Free time counts every calendar, even when you're looking at one category
  • Turn off Blocks Free Time for a partner's or a birthdays calendar and it stops taking up your time
  • Find Free Time searches further ahead and ranks the best slots
The dashboard with the Free chip on: Monday's events in order, with an open 45 minutes marked as free between them

See exactly what collides

Events that clash with something you're going to say so right in the list. Open one to see the clash on its day's timeline, with what's around it, and tap any block to jump to that event.

Every invitation still waiting

Everything you haven't answered, in one list with a Reply button on each. Group by date or by who invited you, combine a weekly invitation into one row, and see at a glance which ones overlap what you've already said yes to.

  • On your dashboard, in your briefings and in the Daily Briefing widget
  • Ask Siri: “Show my invitations in Horizon”
  • Apple Watch tells you how many are waiting

When it isn't sure, it asks

Is “Coffee with Marcus” work or social? When Horizon can't tell, Quick Categorize asks, one title at a time, with its best guesses ready to tap. One answer covers every event with that title, so a weekly meeting takes a single tap. It learns from every answer, so next time it knows.

When Horizon makes a guess it isn't sure of, a small question mark sits on the event's icon. Touch and hold the event to say it looks good, or review the guesses together in Settings whenever you like.

Made for iPhone Duo

Horizon reads the fold, not the width. Close your Duo and your day fits the cover; open it and Horizon becomes a planner, with nothing covering the calendar.

  • Closed, the day fits the cover with controls down the side
  • Open, the month or week sits beside your day, details beside those
  • Folded like a book, the calendar and the details each get a page
Horizon on iPhone Duo, open: the month on one side, the day's events on the other, with Horizon's controls down the edge

Where you'll see it without opening the app

Most of the time, the right moment to know about an event isn't when you're in a calendar app. Horizon shows up where you already look.

Your calendar stays yours

Horizon does its work on your iPhone and iPad. Here's what stays there, and the little that doesn't.

Read the privacy policy
Categorized on your device
Horizon decides each event's category on your iPhone or iPad. There is no Horizon server, so your events are never sent to one.
No account, no tracking
No sign-up, no analytics, no ads and no third-party code. Horizon doesn't know who you are.
iCloud Sync, in your iCloud
Your categories and their weekly goals, corrections, settings and Watchlist sync between your devices through your private iCloud account. That includes the titles of events you've corrected or watched. You can turn it off in Settings.
Weather and maps from Apple
To show weather and maps, Horizon asks Apple's WeatherKit and Maps about your location or an event's address. Apple handles those requests under its own privacy policy.

See what matters on your calendar

Horizon works with the calendars you already have. Open it, allow calendar access, and your events are sorted in moments.
