CalUnity solves the broken cross-calendar sync problem by taking a different approach entirely. Instead of trying to sync Google Calendar into Apple Calendar (where events get jumbled, syncs break, and edits don't propagate), CalUnity connects directly to Google, Apple, and Microsoft APIs and renders everything in one clean unified view. Your events stay in their original calendars — CalUnity just shows them all together. Works across iOS, Android, and web. Includes an AI assistant that finds free slots across all calendars and detects conflicts. 100% free, no ads, no subscriptions.
