3.2GPA

Very good · out of 4.0 · graded Oct 9, 2026

Best for keeping work and personal calendars in step

Got a work calendar and a personal one that keep double-booking you? CalendarBridge copies events between them, so each shows when you're really busy, and you choose how much detail goes across. It starts at $4 a month. But there's no free plan, the trial is 7 days, and that $4 covers one pair of calendars. Three synced to each other means the $8 plan.

Who CalendarBridge is for

  • Great if your work, personal and client calendars need to block each other out
  • Handy when you're a consultant working inside several clients' accounts at once
  • Good for organisations syncing calendars across Microsoft 365 and Google, with an admin managing it

Who CalendarBridge is not for

  • Skip it if you want a free plan, because there isn't one and the trial is 7 days
  • Tight if you have three calendars to keep in step, since Basic's 2 connections cover only one pair
  • Not for you if you want the AI assistant on the cheapest plan, as it starts on Premium

Why CalendarBridge gets a 3.2

Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

  • BValue for moneyBasic is $4 a month billed yearly ($48), with 2 sync connections and 10 scheduling pages. Cheap, but that's one pair of calendars synced both ways. Three calendars need 6 connections, which means Premium at $8, about typical for this category.
  • CFree plan and trialThe pricing pages list no free plan. You get a 7-day trial with no credit card required, and then it's a paid plan or nothing.
  • AFeaturesSyncing is the job and it's done fully: every detail, just a busy block or something between, with events excluded by colour or category. Plans add booking pages, one calendar view for all accounts and, from Premium, an AI assistant you CC on email.
  • BEase of useWe have no App Store rating on record, so a B is the ceiling. You do have to count connections before you pick a plan: each direction between two calendars is one, which takes a minute to get your head round.
  • APlatforms and integrationsWeb, iPhone and Android, across Google Calendar, Microsoft 365, Outlook and iCloud, with Zoom, Meet, Teams and Stripe. An MCP server lets Claude, ChatGPT or Cursor manage events and syncs. iCloud syncs every 5 to 10 minutes, not in real time.

What is CalendarBridge?

CalendarBridge copies events between calendars on different accounts so that each one shows your true availability, with control over how much detail is carried across. Plans also include scheduling pages, a unified calendar on the web and in mobile apps, and, from the Premium plan, an AI assistant that arranges meetings by email. Individuals pick a plan by the number of sync connections they need, and organizations can buy per-user or admin-managed sync licenses.

CalendarBridge is a paid product with a free trial, starting at $4 per user / month, billed yearly ($5 billed monthly). See every plan

Good for

  • People who need work, personal and client calendars to block each other
  • Organizations syncing calendars across Microsoft 365 and Google tenants
  • Consultants and fractional executives working inside several client accounts

Worth knowing

  • The pricing pages list no free plan, and the trial lasts 7 days.
  • The AI Scheduling Assistant is not part of Basic, and a custom email domain for the assistant needs Pro.
  • Basic allows 2 sync connections, enough for one pair of calendars synced both ways; three calendars synced to each other need 6.
  • Real-time syncing is stated for Google and Outlook events; the help center says syncing from iCloud or .ics calendars runs every 5 to 10 minutes.

Key features

Real-time calendar syncing
When an event is created or changed on one calendar, a matching event is created or updated on the others. The pricing page says Google and Outlook events typically update in under a minute.
Control over what is copied
Sync every detail, only a busy block, or something in between. Events can be excluded by color or category, and copies can carry an identifier or a color that shows their source.
Scheduling pages
Every plan includes up to 10 booking pages that check availability across connected calendars, with buffers, daily limits and minimum notice. Stripe can be connected to take payment at booking.
Unified calendar
View and edit events from all connected calendars in one place on the web, iPhone and Android. The number of calendars shown at once is 4, 12 or 24 depending on the plan.
AI Scheduling Assistant
On Premium and Pro, you CC or forward an email thread to the assistant; it proposes times from your availability, follows rules written in plain English and books the meeting.
Group licensing and MCP server
Group accounts put 2 or more users on one bill and can mix user licenses with admin-managed sync licenses. An MCP server lets agents such as Claude, ChatGPT or Cursor manage events and syncs.
