Everything you need to tame your calendars
One app. All your schedules. Right where you need them.
Auto-sync every 15 min
Caldzy polls your ICS feeds continuously and pushes changes to iCloud Calendar — no manual refresh, ever.
Zero duplicates
Smart deduplication means events are never created twice, even if the same feed is synced from multiple devices.
Change alerts
Get notified the moment an event is added, updated, or cancelled — so you're never caught off guard.
Smart Arrival
Caldzy reads arrival notes in event descriptions ("arrive 30 min early") and automatically sets a custom reminder.
Family sharing
Share any calendar subscription with family members so everyone stays in sync — without exchanging ICS links.
Multiple syncs
Manage as many calendar feeds as you need. Sports teams, school events, work rosters — each in its own iCloud calendar.
Up and running in 3 minutes
No plugins. No browser extensions. No waiting.
Connect iCloud Calendar
Sign in with your Apple ID email and app-specific password. Caldzy uses CalDAV — the same standard Apple uses — to write events directly to your calendars.
Your credentials are stored encrypted in Supabase Vault and never leave the secure server-side sync environment.
Paste an ICS feed URL
Copy any webcal:// or https:// feed link — from Google Calendar, Teamsnap, your school's website, anywhere — and give it a name.
Caldzy also accepts .ics file imports. Tap the share sheet on a .ics attachment in Mail and Caldzy opens with the URL pre-filled.
Relax — Caldzy does the rest
Events appear in your iCloud Calendar within 15 minutes. Changes are tracked, duplicates are removed, and Smart Arrival sets reminders automatically.
Because events live in iCloud Calendar, they sync to your iPhone, iPad, Mac, Apple Watch, and any app that reads iCloud.
Loved by people juggling real schedules
"My son plays on three baseball teams and every team had a different schedule app. Now I paste the webcal link, it just shows up in my Calendar. Game changer."

"I work shifts across two hospitals. My employer posts the rota as an ICS feed but it never synced to iCloud. Caldzy fixed that in literally two minutes."

"Smart Arrival is the feature I didn't know I needed. My uni events say 'arrive 20 min early' in the description — Caldzy just picks that up and sets the alert."
