Google Appointment Scheduling
On free and personal Google, Appointment Scheduling only checks your primary calendar for conflicts — so people book right over the busy time on your other calendars. Calendar Sync fixes that in about a minute, without a Workspace upgrade.
Then just $0.99/month. No card required to start.
Google's "book time with me" page (Appointment Scheduling) is genuinely useful — but on a free or personal Google account it has one big blind spot: it only looks at your primary calendar when deciding which slots are free.
If you keep work on one calendar, personal life on another, and a side project on a third, your booking page can't see two of them. So someone books a "free" slot that's actually a school pickup, a client call, or a dentist appointment — and you're double-booked.
Google's own fix is to upgrade to Workspace Business Standard (~£10/user/month) so Appointment Scheduling can check multiple calendars. For one person's booking page, that's a lot to pay for one setting.
Calendar Sync mirrors the busy time from your other Google calendars into the one your booking page checks — as clean, private "busy" blocks (no titles or details leak). Your free Appointment Scheduling page then sees every commitment and only offers slots you're genuinely free. Same result as the paid upgrade, for a fraction of the price.
Sign in with Google and link the calendars you want your booking page to respect.
Mirror your other calendars' busy time into the one your booking page uses.
Your Appointment Scheduling page now shows only truly-free slots. No more double-booking.
Tip: after syncing, tick the synced calendar under "Calendars checked for availability" in your Appointment Scheduling settings so the busy blocks are applied.

On free and personal Google accounts, no — it only checks your primary calendar. Busy time on your other calendars is ignored, so people can book when you're actually busy. Checking multiple calendars is a paid Workspace Business feature.
Sync the busy time from your other Google calendars into the one your booking page checks. Calendar Sync mirrors your events as private "busy" blocks so your page sees every commitment and offers only free slots.
No. Upgrading is one route (~£10/user/month), but Calendar Sync gets you the same outcome — your free booking page respecting all your calendars — for $0.99/month.
Yes. Only busy time is copied, as generic "busy" blocks — titles, guests and details never leave your original calendar. Data is encrypted and you can disconnect and delete it anytime. See our Privacy Policy.
