6 Best Calendar Apps for Organizing Your Week for 2025

Time is the center of the universe. Does that make calendar apps the best productivity app?

You don't have to be a time management fiend to want to use a calendar application to better organize your events, meetings, and maybe even time blocks. Calendar apps are some of the most common productivity tools because they focus on time at their core.

Navigating calendar applications is like buying a car, so many brands, so many offerings. Which one to pick right? We feel you. The range of calendar applications is expansive and we've now seen the rise of tools like meeting planners, chrome extensions for your calendar, and smaller calendar apps too.

What makes a great calendar app?

Calendar apps are hard to pick because they look the same and present many of the same features, like the ability to time-block, add events, descriptions, reminders & video conferencing optionality. Here's what we believe make a calendar app brilliant:

• Scheduling Functions - The best calendar apps should allow you to better plan meetings and events with people using meeting scheduling functions. This is becoming much more common and not every calendar app has it, but that's what makes them better. There's nothing worse than investing your time into a calendar app and using a 3rd party service like Calendly to book meetings. Two tools can become one.

• Super Mobile Apps - Calendar is hard to get right on mobile thanks to the tiny real-estate when compared to a wide screen desktop display, so the best calendar apps make it easy and resourceful of the space on their mobile app version. Cracking examples are ones that make it easy to navigate between dates and don't overwhelm with features but deliver what's needed to view, schedule in and even plan meetings.

• Increasing AI Abilities - There's more need for AI to do smaller errands in the background of your calendar apps. The more prevalent calendar apps will need and activate AI to do things like plan your tasks into your calendar, save time with suggested dates & recommend the best slots for you and people to work with. Less meetings and more focus time is the best motto.

Best Calendar Apps

Our top picks for the best recommendations on calendar:

1. Morgen

Best for All Round

• Morgen helps you plan tasks, manage your calendar and connect with other integrations like Todoist, Google Tasks and beyond, with a Notion integration coming too.

• Alongside your calendar events and meetings you can see a task list with the ability to create tasks and create lists for better planning, you can then use this to time-block into the schedule.

• Morgen is probably even better as an all-rounder than the likes of Fantastical to be honest. It brings a wide variety of devices, good design, and a speedy app that allows users to add tasks and calendar items with ease. Much like Fantastical it offers a clean and simple design, and with the same freemium limitations too that you'd expect to see in Fantastical.

2. Fantastical Calendar

Best for All Round (iOS)

• Fantastical is free and offers a good way to add meetings, events and weather forecasts. It is simple, with "natural language input" for quickly adding events. Fantastical was developed by Flexibits, which created an easy, fun, and approachable calendar application.

• Fantastical offers a premium experience which does give you better and bolder access to conferencing, productivity features like sets for managing your tasks and calendar in one and even a meeting scheduling link that you can send out externally to book meetings. This is just one of the classics in the productivity space as far as calendar apps.

• For those Apple centric (iOS and macOS) users, that want a great all-round calendar app. This is one of the best ones the market. Fantastical is brilliant for managing events, using natural language to add quick tasks, and managing light tasks alongside events.

• Notion Calendar is free, works with Google Calendar and has a stunning desktop and mobile design.
