ReciproCal Sync
Rule-based calendar sync
Free · In‑App Purchases
ReciproCal keeps your calendars in sync — on your terms.
Set simple rules to copy events from one calendar to another automatically: only during work hours, only when the title contains a keyword, or with a neutral "Busy" placeholder so private details never leak into a shared calendar.
Everything runs entirely on your device. There is no account to create, no server to trust, and your calendar data never leaves your iPhone, iPad or Mac.
RULES THAT FIT YOUR LIFE
• Time-window rules — sync only what falls inside (or outside) the hours you choose
• Keyword rules — match events by words in the title, location or notes
• Optional masking — publish a neutral "Busy" block instead of the real title and details
• One-way and loop-free — each rule syncs in a single direction, so copies never bounce back
PRIVATE BY DESIGN
• 100% on-device — no account, no analytics, no data collection
• Optional iCloud sync keeps your rules (never your events) in step across your devices, using your own private iCloud
BUILT FOR APPLE
• Native iPhone, iPad and Mac app
• A calendar view that shows exactly which events are synced, in both calendars' colors
• Shortcuts and a Home Screen quick action to sync on demand
• On Mac: an optional menu-bar agent that keeps syncing in the background
ReciproCal Pro (optional) unlocks unlimited rules, full custom masking, automatic background sync and the macOS menu-bar agent. The free plan lets you set up one rule to try it out.

Optimiert für das iPhone Duo: Alle Schaltflächen erscheinen jetzt in der Seitenleiste, wenn sie senkrecht angezeigt wird.
Behebt einen Absturz, der auftreten konnte, wenn die App auf dem Mac im Hintergrund gestartet wurde (zum Beispiel durch iCloud-Synchronisierung).
