About Horizon
Most calendar apps want you to move your life into them. Horizon doesn't. It sits on top of Apple Calendar and works with whatever is already there: iCloud, Google, Exchange, Outlook and CalDAV calendars.
Horizon's AI sorts every event into one of 19 categories, on the device, and learns from each correction. You can add categories of your own too. From there, Horizon answers the questions a calendar usually leaves to you: what's left today, when you're free this week, which invitations still need a reply and what they overlap, and where your time actually went over the last few months. The Watchlist counts down to the trips and birthdays you care about, on the Lock Screen and Apple Watch, and weekly goals track things like “at least 3 workouts”.
The story
Steve built Horizon for two people: himself and his wife. Their calendars held everything, from work meetings and appointments to birthdays and trips, and Apple Calendar showed all of it the same way, so the things that mattered had to be dug out from between the meetings. He wanted one screen that answered the questions a calendar leaves to you: what's left today, when are we free, how long until the trip.
He started on March 22, 2026, and twelve days later the first version was on the App Store. It has grown release by release since: birthdays and trips that step aside so the day's real plans come first, a switch so a partner's calendar doesn't block your own free time, invitations that wait in their own list until you answer, and goals for the things you mean to do more of. October alone brought four releases, 1.6 through 1.9.
It's still one person's app, with no account, no ads and no servers. It was made for two people, and it's free through November to find out what it needs to work for everyone else.
