SyncBusy vs Reclaim, OneCal, CalendarBridge and doing it yourself
Short answer
SyncBusy fits if your work calendar is Google, your personal one is Google or iCloud, and all you want is private busy blocks, with a free plan. OneCal and CalendarBridge fit if your work calendar is Outlook or Microsoft 365, or you need to sync many calendars in several directions. Reclaim.ai fits if you also want AI scheduling, habits and focus time, and your calendars are Google or Outlook.

Where SyncBusy is the better fit
- You only need busy blocks. SyncBusy does one job, so setup is two sign-ins and there's nothing to configure.
- You want it free. The free plan has no trial period: busy blocks 14 days ahead, for as long as you like.
- Privacy matters. SyncBusy reads your personal calendar read-only, writes only its own private events at work, and stores no event titles, just a one-way fingerprint.
- Your family needs your work schedule. Reverse sync (Pro) copies accepted meetings to a family-visible Google or iCloud calendar.
Where SyncBusy falls short
- No Outlook or Microsoft 365. The work calendar has to be Google Calendar.
- One personal source per account. Either Google or iCloud. Several iCloud calendars are fine, but mixing Google and iCloud means two accounts.
- Not a scheduling assistant. No booking links, task planning or AI rescheduling. Reclaim.ai and others do that.
- A small independent studio. SyncBusy is made by Lvenok Studios, not a large company.
Doing it yourself
Share your personal calendar with your work account
Free, and you'll see your appointments at work. Coworkers won't: scheduling checks your work calendar, and a shared calendar doesn't block it. See blocking personal appointments.
Subscribe to a public iCloud link
Free, but the calendar becomes readable by anyone with the link, Google refreshes it only every few hours, and it still doesn't block your time for coworkers. See the iCloud guide.
Zapier or Google Apps Script
Workable if you like building automations. A basic Zapier zap copies new events only, so edits and cancellations need more zaps, and free plans cap monthly runs. A script can do more, but you maintain it.
Try SyncBusy
Free to start, no card needed. Connect your personal Google or iCloud calendar and your work Google Calendar, and your busy time shows up within minutes.
