Horizon: Calendar Highlights, an iPhone, iPad and Apple Watch app that organizes your Apple Calendar by category, is free on the App Store through November 30, according to its listing. The outlet New Mobile Life reports that the normal price is US$0.99.

The developer, Steve Villardi, says on the listing that he built the app for his wife and is now offering it free to everyone for a limited time.

What does Horizon do?

Horizon reads the events already in Apple Calendar and sorts them into categories such as Work, Health, Family and Travel. It then pushes the important ones forward on a dashboard, in briefings, in widgets, on Apple Watch and through Siri. There is no new calendar to maintain and no account to create.

Here are the main features the listing names:

  • 19 built-in categories, with the option to add your own and learn from your corrections
  • Quick Add: type a phrase such as “Lunch with Priya Friday at noon” and the app fills in the day, time, length, place and repeat pattern
  • A Daily Briefing showing how much is on, when it starts and ends, and where your free time is
  • A Weekly Briefing with busiest days, conflicts and a Life Patterns view of where your time goes
  • Weekly goals, for example at least 3 workouts a week or at most 20 hours of Work
  • A Watchlist that counts down to a trip, birthday or concert, with a Live Activity on the Lock Screen and in the Dynamic Island

It works with every calendar inside Apple Calendar: iCloud, Google, Exchange, Outlook and CalDAV. The same meeting on two calendars appears once.

Which languages and devices does it support?

Version 2.0 added six interface languages: English, German, French, Spanish, Italian and Simplified Chinese. Events written in any of the six are sorted into the right category, so a German “Zahnarzt” lands next to “Dentist” under Health. The listing also describes a Morning Time setting that delivers everything about the day ahead together, as a briefing or a single notification.

The download is 40 MB and the age rating is 4+. The listing says the app is designed for iPad and is not verified for macOS.

Is it private?

The developer says categorization runs entirely on your device, that your events are never sent to a server, and that there are no Horizon accounts and no tracking. Categories and settings follow you to your other devices through your own iCloud account. This is the developer’s own description, and we have not audited it.

How much does it cost?

The App Store listing shows the app as Free and says it is free through November 30. New Mobile Life puts the regular price at US$0.99. The listing does not say what the price will be after the promotion ends, and it does not say which countries the free offer covers, so check the price in your own store before you rely on it.

Who should get it?

People who live in Apple Calendar. If your events already sit in iCloud, Google or Outlook calendars, Horizon adds categories and briefings without moving anything.

People with weekly habits to track. The goals feature suits anyone who wants a minimum of workouts or a cap on work hours to show up next to their schedule.

Anyone cautious about new accounts. The listing promises no sign-up, which removes one common barrier.

Who should wait. The app is young: the listing shows 5.0 stars from 10 ratings, which is too few to judge long-term reliability. If you need a Mac version, the listing does not offer verified support.

What is not known yet?

The sources do not say what the price returns to after November 30, whether existing buyers get any change, or how the free offer applies outside the countries where the listing was checked.

Next step: open the Horizon: Calendar Highlights page on the App Store, confirm the price in your region, and download it before November 30 if it suits you.
