Your Apple Calendar, intelligently organized. Horizon is the smart companion for Apple Calendar. It reads your existing events, automatically organizes them into meaningful categories, and surfaces what matters most, so you spend less time managing your schedule and more time living it. No new calendar to maintain. No accounts to create or connect. Horizon works on top of the calendars you already use, adding a layer of intelligence that Apple Calendar doesn't have. Smart Categories - Horizon automatically classifies your events into 19 categories, Health, Work, Family, Travel, Social, Finance, and more using on-device intelligence. Every event gets a category, a color, and context. You can customize categories, add your own keywords, or override any classification with a tap. Daily & Weekly Briefings - Start your morning with a glance at what's ahead: today's timeline, weather, your next event spotlight, how your time breaks down by category, and open slots in your day. Weekly briefings give you the bigger picture, your busiest days, category distribution, highlights, and scheduling conflicts. Find Free Time - Looking for time to exercise, focus, or catch up with a friend? Horizon scans your schedule and finds available slots that match your preferences then lets you book them in one tap. Duplicate Cleanup - The same meeting showing up on two calendars? Horizon automatically detects and merges duplicate events so your schedule stays clean and accurate. Quick Categorize - Triage uncategorized events fast. Horizon suggests a category based on what it's learned, and you confirm or change it with a single tap. Widgets That Work - Home screen and Lock Screen widgets keep your schedule visible without opening the app. See your next event, today's briefing, or your week at a glance. Smart Notifications - Reminders that understand context. A doctor's appointment gets a reminder a week ahead. A work meeting gets one 30 minutes before. Each category has its own timing and you can adjust them all. Built for Privacy - All intelligence runs entirely on your device. Your calendar data never leaves your iPhone. No servers, no tracking, no accounts. Designed for Apple Calendar - Horizon is purpose-built for iCloud, Exchange, and CalDAV calendars synced through Apple Calendar. Deep integration means fast syncs, reliable data, and zero setup. Just grant calendar access and Horizon handles the rest. ## Key features - Smart event categorization - Daily and weekly briefings - Find free time suggestions - Duplicate event cleanup - On-device privacy - Home and Lock Screen widgets - Context-aware notifications ## Chart rankings - #190 in Top Paid · Productivity (US App Store) ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/horizon-calendar-highlights/id6761135453/reviews.md ### 5/5 — Awesome *2026-04-16* Simple app that makes finding time in my calendar much easier.
