# Best scheduling apps for multiple calendars

For one booking link across Google Calendar and Outlook, consider Calendly for a paid setup, SavvyCal for guest calendar overlays, or YouCanBookMe for a custom booking page. Investigate Cal.com if free is essential, but the sources disagree on its free calendar allowance.

For one person, two calendar accounts and around 40 half-hour appointments a month, with a third client calendar as the growth case. This comparison covers booking links that check availability across your calendars; combined calendar views, calendar mirroring and multi-host scheduling are separate needs.

## Calendly

For a paid Google + Outlook booking setup, consider Calendly. Zeeg describes checking several connected calendars for conflicts and sending new bookings to one chosen calendar. It lists six calendar connections on Standard and higher, so this is a practical starting point when your personal and work commitments live in separate accounts. Zeeg lists only one calendar on Free. It also says the same calendar configuration applies across event types. Confirm the current allowance and destination behavior if different appointment types need different calendars.

## SavvyCal

For letting guests compare their own schedule while booking, consider SavvyCal. OneCal describes a calendar overlay that helps guests find a suitable time, alongside Google and Outlook integration and availability checks across multiple calendars. That makes SavvyCal worth investigating when the booking experience matters as much as managing your own schedule. Budget for a paid plan: OneCal and YouCanBookMe say creating your own booking links requires one. Zeeg describes a free link instead, so verify the current entitlement and destination setting before committing.

## YouCanBookMe

For a customizable booking page for client appointments, consider YouCanBookMe. Cal.com highlights customizable booking pages and support for Google Calendar and Outlook. It lists two calendars on Individual and six on Professional. Zeeg also describes conflict checks across connected calendars. This is a useful lead if you want control over the booking page clients see. Check what the plan counts as a calendar, where appointments are written, and what adding a third calendar costs. We could not establish a comparable current bill from the eligible sources.

## Cal.com

For investigating a free multi-calendar option, consider Cal.com. OneCal describes Google and Outlook integrations and shareable booking links. Both Zeeg and YouCanBookMe list unlimited calendar connections on the individual Free plan, making Cal.com a candidate to examine if avoiding a subscription is important. Koalendar instead lists one calendar on Cal.com Free cloud. Because those descriptions conflict, do not assume the free plan covers two accounts. Test both-calendar conflict checking and the booking destination before sharing a live link.

## Multiple calendars: three different jobs

For this comparison, the job is appointment booking: a client opens your link and sees a slot only when your connected calendars allow it. You want a work meeting in Outlook and a personal appointment in Google Calendar to affect that same link.

A combined calendar view solves a different problem: seeing your own day in one place. Busy-time mirroring is different again: copying a block into another calendar so colleagues can see you are unavailable. A booking tool checking both calendars does not, by itself, establish either of those features.

Also separate calendars from people. Connecting your own third account is not the same as adding another host. If a meeting needs several staff members to be free, you need a comparison of team scheduling and shared availability.

## Which plan should you check first?

If paying is acceptable, start with Calendly Standard and confirm its current connection allowance. For a more customizable client-facing page, investigate YouCanBookMe Individual for two calendars and ask what changes with the third. For SavvyCal, make the guest overlay part of your trial.

If free is a hard requirement, examine Cal.com, but treat its entitlement as an open question. “Has a free plan” is not enough: the plan must support your two accounts, check both for conflicts, and create the appointment where you need it.

Before comparing prices, write down the exact account setup: for example, one Google account containing personal and family calendars, plus one Microsoft 365 work account. Ask whether limits count connected accounts, selected calendars, or host seats. Those are not interchangeable.

## Check your two calendars before sharing a link

Use test events without client details. These are suggested checks, not tests we have performed.

1. Connect your personal Google and work Outlook accounts. Select which calendars should block availability.
2. Add a busy test event to each calendar at different times during your available booking hours. Open the booking link in a private browser window and check that both slots disappear.
3. Book an available slot. Confirm the new event appears in the work calendar you selected, with the expected time zone and meeting details.
4. Reschedule, then cancel the test booking. Check the destination event and the availability shown on the booking page.
5. If you expect to add a client calendar, connect a third one during the trial and check the actual upgrade requirement.

## Does an appointment appear in every connected calendar?

Do not assume it does. A scheduler can read several calendars to calculate availability while writing a new appointment into just one. Zeeg describes that pattern for Calendly. Decide where you want client appointments to live, then check the destination setting in your chosen tool.
