Stop Calendar Conflicts.

From Calendar Chaos
to Perfect Sync
Out‑of‑sync calendars create blind spots.
Events live in silos. You can't see your real availability because calendars don't share state.
- Add an event in Personal calendar, but Work stays clueless.
- "Busy" on one account doesn't block the others.
- You think you're free, but the other calendar says otherwise.
You only notice when two events collide.
Hidden overlaps become emergencies. Two events land on the same slot and now you're double‑booked.
- The same time block fills twice
- You discover it at call time, not before.
- Awkward rescheduling, lost time and trust, annoyed people.
Conflicts caught. Calendars synced.
One click, one clean schedule.
- Mirror the event from one calendar to the other calendars you've linked.
- Respect your privacy: copy full details when you need transparency, or just drop a "Busy" block when you don't.
It's still your Google Calendar. Just smarter and always in sync.
