The majority of calendar apps connect to Google, Apple or Outlook calendars.

This allows us the freedom to roam and upgrade the look of you calendar with third-party calendar apps.

A lot of the calendar apps on the market are premium or offer a paid subscriptions, so we've found the best free calendar apps out there.

What do we want from a free calendar app?

Here's what to expect from our recommendations:

  • Connect Services - At least connects one of the popular services you already use like Google, Outlook or Apple Calendar.

  • Handle the Basics - You don't want to worry about limits of using and adding the basic calendar features.

  • Optional Upgrades - If you seek more power or features, beyond the basics, you can upgrade easily to bolder plans.

Despite Google, Apple & Outlook offering their free calendar experience, these are all third-party apps.

They can plugin with those services, but we didn't want to recommend those tools, as they are the core foundations for most apps.

1. Notion Calendar

Best for Cross Platform

Notion Calendar is a calendar app developed by the Notion team.

It helps you handle Google & iCloud calendars on one platform, on a wide range of devices. Notion Calendar is totally free making it a great candidate for the job. It helps make those calendars easier to browse, with scheduling links for booking meetings, easy to use layout and a beautiful set of apps that work fast. Despite being free, it deeply embeds with Notion pages & databases, so if you're a Notion nerd already, you'll find it perfect for your needs. Many people like you can use it on iOS, Android, mac & Windows without issues - making it perfect cross-platform tool.

It is likely Notion will add Notion AI soon that upgrades features for premium Notion users, but this shouldn't affect the core free experience.


What's part of free?

  • There's no pricing meaning everything is free.
