10 best calendar apps on Android in 2024 (2024)

Choosing a calendar app that suits your needs is important if you have a busy life. While most apps share the same basic features, each offers a unique set and look that suits specific situations. Google Calendar works well and is preinstalled on our favorite Android tablets, but plenty of other options are worth investigating if you're looking for more depth or integration. We gathered the best calendar apps together so that you can easily find one that works for you.

1 Google Calendar

The calendar that everyone knows

If you're comfortable with the Google ecosystem, Google Calendar is a no-brainer. It's free, works with other Google apps like Gmail, and has a beautiful Material You appearance for those with Pixel phones.

Google Calendar's integration with other Google apps means that it suggests names, locations, and contact details when you add events. It can even scan Gmail for emails containing event information (such as flights or meetings) and automatically add them to your calendar.

2 Simple Calendar

Straightforward and simple to use

Simple Calendar is one of the most straightforward calendar apps available on Android. While other apps try to pack in as many features as possible, Simple Calendar keeps things simple. But don't be afraid of losing out on features. While it may not have smart suggestions or a Material You design, it gives you enough options to customize the app. It's also part of the Simple Mobile Tools suite of apps, so you can have an open source ecosystem with a coherent theme.

3 CalenGoo

Vast customization options and versatility

CalenGoo is a versatile calendar app that can appear slightly overwhelming due to the vast customization options. One of its notable features is its range of 31 widgets (Google Calendar has two). Each widget can be customized with options to change how your calendar looks. It's perfect for people who get frustrated with other apps' limitations. It's also packed with features from Evernote integration to to-do lists within events.

4 DigiCal

Similar to Google's aesthetic and functionality

DigiCal is for people who love Google's aesthetic but don't want to use their apps. It offers a clean, minimalist interface and Material You integration. The core app is free, but we recommend upgrading to DigiCal+ if you use this as your primary calendar app. This premium version removes ads. It includes features like a heat map to spot free and busy periods and detailed weather forecasts. Plus, it'll only set you back $5.49.

5 Any.do Tasks and Calendar

A solid calendar for over a decade

Any.do is a combination to-do list, planner, and calendar app. While many calendar apps offer similar features alongside a calendar, Any.do feels like three apps rolled into one. It's perfect for people who need a to-do list app, calendar app, and planner but don't want to constantly switch between apps. It doesn't have an overload of features, and it's cleverly designed to show you everything you need at a glance.

6 One Calendar

View all your calendars in one

One Calendar brings all your calendars together into an easy-to-read overview that can be viewed as a whole or on a calendar-by-calendar basis. While many calendar apps offer this feature, One Calendar's organized interface gives you a clear overview of your events. However, it is a bit light on other features, so it might not be the best solution if you don't use multiple calendars.

7 TimeTree

For organizing groups of people

TimeTree is dedicated to sharing events with others. While other calendar apps allow you to add contacts to events or share an event, TimeTree also offers various features for those constantly organizing groups of people. For example, each event has a chat room, so you can discuss it in a dedicated space, and you can create separate calendars for each of your groups. If you organize and share a lot of events, this is the app for you.

8 Calendar by Calendar Date

A slimmed-down version of Any.do

Calendar by Calendar Date might not have the most exciting name, but it offers a brilliant range of features. It feels like a slimmed-down version of Any.do. If you tried Any.do and found it overwhelming, Calendar might be perfect. Its minimalist interface keeps things clean without losing out on detail, and navigating the app is intuitive. If simple is what you want, you'll find it here.

9 Business Calendar 2

WearOS support and Google Calendar integration

If you're struggling to move away from Google Calendar, Business Calendar 2 should be your first step. Don't worry about the name. This app is just as suitable for personal use. It integrates perfectly with Google Calendar and can be installed on WearOS devices. Beyond this, it has all the features you can expect from a calendar app, including a planner view, heat maps, schedule sharing, and more.

10 Proton Calendar

A calendar made for privacy

If you are concerned about privacy, Proton Calendar has you covered. It's based in Switzerland, and all your data is covered by Swiss privacy laws. There is full end-to-end encryption with zero access, meaning they can't spy on your activities or use your data. You won't find ads, trackers, and data sharing with third parties. The calendar functionality includes all the standards, like a schedule planner, recurring events, reminders, three personal calendars on a free account or up to 25 calendars with a paid account. Proton has a full suite of tools, including a mail app, cloud storage, VPN, and password manager.

Manage your dates, times, and locations with the best calendar apps

Choosing a calendar app is as challenging as choosing any other productivity app. Our top recommendation is to set up your calendar on Google Calendar and sync it to other calendar apps. This method means you can try multiple calendar apps without losing track of your events and getting confused. However, to keep your data as secure as possible, like you can with Proton Calendar, try one of these open source calendar apps.
