CalendarBridge pricing explained: plans, limits and billing

CalendarBridge has three individual plans: Basic at $4 a month, Premium at $8 and Pro at $32 when billed yearly, or $5, $10 and $40 when billed monthly. The plans differ by synced connections (2, 20 and 56), and there is no free plan; the trial needs no card. Keeper.sh, a calendar sync service, publishes this page. Every CalendarBridge figure comes from CalendarBridge's own pages: its individual pricing page and group pricing page, checked 10 November 2026, the help article the pricing table links to, and its work and personal calendars page for the trial length, checked 10 November 2026.

Yearly and monthly billing

Yearly billing is 20% less than monthly: the page's toggle reads "Yearly 20% OFF". Twelve months at the yearly rate come to $48 for Basic, $96 for Premium and $384 for Pro, against $60, $120 and $480 at the monthly rate.

The plan cards word the calendar limit differently by billing period. The yearly cards read "2 Calendars", "5 Calendars" and "8 Calendars". The monthly cards read "Add Unlimited Calendars". The comparison table under the cards lists the same synced connections for each plan whichever period you pick: 2, 20 and 56.

What a synced connection is

A synced connection copies events from one calendar to one other calendar, in one direction. CalendarBridge's help article on the subject, linked from the pricing table and last updated 11 April 2024, gives two examples with calendars X, Y and Z: copying X to Y and Z to Y "requires 2 sync connections", and "Copying events from each of X, Y, and Z to each other requires 6 sync connections" (how many sync connections do I need?, checked 10 November 2026).

For every calendar to show every other calendar's events, the count is the number of calendars multiplied by one less than that number:

CalendarBridge's article says 2 calendars need Basic, 3 "probably need a premium plan", 4 "definitely need premium", 5 fit Premium exactly, and 6 to 8 "probably need pro (up to 56 sync connections)", or Premium if not every calendar has to show every other. With 9 or more calendars, "there is no way on an individual account to have all calendars reflect all other calendars".

Fewer connections are needed when the sync does not have to run every way. Two calendars that each copy into a third use 2 connections, which fits Basic.

What every plan includes

The pricing page lists these on Basic, Premium and Pro:

• Unlimited synced events, described as "Sync all future events on your calendar".
• Up to 10 scheduling pages.
• The Unified Calendar on web, iPhone and Android, viewing 4, 12 or 24 calendars at once depending on the plan.
• Real-time syncing for Google and Outlook events: "Events typically update in under a minute" (the pricing page's wording).
• Control over what syncs: "Sync all details, just 'busy,' or somewhere in between", and exclusions by colour or category.

A HIPAA business associate agreement "is available for premium and pro plans", which matters for healthcare teams.

Trial and group pricing

The pricing page says "No credit card required to start your trial" and does not give the trial's length. CalendarBridge's page on syncing work and personal calendars gives it as 7 days.

Groups of 2 or more users are priced on a separate page. User licences cost the same as the individual plans and go on one bill, and sync licences managed by an administrator start at $3.20 per connection a month billed annually, or $4 billed monthly (CalendarBridge group pricing).

How Keeper.sh's pricing compares

Keeper.sh is a calendar sync service that copies events between Google Calendar, Outlook, iCloud, Fastmail and any CalDAV server. Each copy is a busy block named after the source calendar. The title, description and location are hidden by default, Pro can turn them back on per calendar, and guest lists are never copied. Each connection runs one way, so two-way sync is two connections; the calendar sync features page lists what else each connection can do. The Free plan covers 2 calendar accounts and 3 connections, with changes landing every 30 minutes. Pro is $5 a month or $45 a year, with Google and Outlook changes landing within seconds and iCloud, Fastmail and CalDAV changes landing every minute (pricing).

Keeper.sh's Pro plan does not limit calendars or connections, so 6 calendars that all show each other's events cost $5 a month. The CalendarBridge alternative page compares the two products beyond price, including CalendarBridge's scheduling pages, combined calendar app and HIPAA business associate agreement.

Plans and limits explains what counts as an account and a connection, and how to sync Google Calendar and Outlook walks through a two-way setup.
