What Makes The Best Calendar App for Android?

When looking for the best calendar app for your needs, you need to consider several important aspects of such a tool. First of all, look for a calendar that works with both personal and professional needs. While it’s possible to manage multiple calendars, it’s surely not easy, nor convenient. However, it’s important to note that most of the apps on our list enable you to create separate calendars for different needs.

Calendar apps often allow users to set specific reminders or alerts for tasks, which can improve adherence to deadlines.

Secondly, focus your attention on calendar apps that can be accessed from different devices (sometimes, you may need to use your phone, but on other occassions, you may want to access your calendar from the computer). Sincing with other tools (e.g., Google Workspace but also your website’s booking system, if e.g., you’re a consultant or a freelancer) is also a nice-to-have feature allowing you to save a lot of time.

Other features that you may find useful depend on your needs and work style. Many users enjoy access to the following features:

• Color-coded events

• Voice input of new events

• Easy event creation

• Recurring reminders (Reminders and notifications are standard features of most calendar apps)

• Time zone support (this feature is extremely useful when you live in California and have meetings with clients in New York)

• Communication with other users (e.g., collaboration features in calendar apps can include comments on events)

Additionally, Calendar apps often have customizable views including daily, weekly, and monthly formats. And if you’re looking for AI support, many calendar apps support natural language processing for event creation.

There are some additional advanced features, such as integration with other calendar apps (e.g., your company’s general calendar) and access for multiple users (e.g., if you have shared schedules with your business partner). Seamless integration across devices allows users to sync entries from their calendar app on their smartphone to a desktop, improving time management.

However, keep in mind not to go overboard. Having multiple calendars or using one that is too complicated will quickly become irritating and overwhelming. You want to make your life easier, not harder!

With that in mind, let’s have a look at some of the best calendar apps for Android. Here’s our list!

How to Pick the Best Calendar App for Android in 2025? 

Selecting the best calendar apps for Android is not an easy task! The apps that we listed in this article are quite similar, so the best thing to do is compare available options and go with the one that makes the most sense in your situation. It’s good to go with an app that offers a desktop version and multiple calendar accounts (or at least multiple calendar views). Also, look for an app that offers real-time reminders. Upcoming event reminders ensure that users do not miss important appointments, contributing to better time management.

Additionally, you should think about your needs and preferences. For example, if you value the security of your schedule, Proton is probably the best app to choose. And if you’re after easy coordination with friends and family, TimeTree might be a good option for you.
