Best Free Calendar Apps for 2025

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.
