Our Review of Google Calendar
When it comes to features, ease of use, and the number of users, Google Calendar is hard to beat. It’s your one-stop shop for all your calendar needs. It handles to-do lists, reminds you of events and appointments, and displays several views of your calendar. It can help you attain your goals by scheduling them. Use it to choose an activity for your goal, and find a regular time in your schedule. If you don’t do an activity, Calendar reschedules it so you stay on track. Now that Google Workspace is available to everyone, it’s also a powerful tool for collaborating with friends, family, or co-workers.

Calendar apps are handy in effectively organizing your time. Still, many of us end up using whichever calendar app comes preinstalled on our Android phones. But the bundled apps are rarely the best ones around. Thankfully, there are many great options to choose from in the Google Play Store, and we present some of them to you in this article.

If you’re privacy-conscious and don’t appreciate your calendar provider having access to your data, you should try out the Proton Calendar app. From the makers of ProtonMail, the Proton Calendar app is currently in beta, so there’s a chance you might run into some bugs. It includes end-to-end encryption so nobody can see your calendar data, including Proton. Additionally, there are no ads or trackers to keep everything private.

In addition to the calendar basics, the app allows you to create recurring events and schedule appointments in any timezone. You can also add multiple notifications to any event. Proton Calendar is also available on the web, and an iOS version is coming soon. The developers promise to add more features as the app moves out of beta. It’s free to download and use.

This paid Calendar Widget from Francisco Franco of Franco Kernel fame is another good option. It gives you a lot of customization options and even allows you to import themes made by anyone. You can choose to show just today’s events or a running list. Also, you can set the maximum number of days shown in the widget. There are several other options to help you tweak the widget to your liking.

There’s a free version of the app, but it’s pretty barebones, and only the paid version makes sense.

If you’re looking for a neat calendar widget for your phone, you may like Month from Candl Apps.

Month also lets you pick which calendars show up in the widget. Lunar Calendar support is present as well.

While widgets are great at giving you a glance at your schedule, they’re only visible on particular home screen pages. So if you want to see your calendar at more locations, Calendar Notify is a handy app. It acts as a companion to your existing calendar app and puts your calendar on your notification shade. You also get regular widgets.

The app allows you to tweak how your calendar looks in the notification shade. Additionally, you can back up or restore your app settings. Calendar Notify is free to download and use. There’s a premium edition as well that unlocks a few additional features.
