If you live your life in both Android and iOS, using Google services is easier. Almost all Google apps are available on iOS. The same is not true if you want to use the Apple services on Android. A typical example: There's no great way to sync your iCloud calendar with Android, but there's an easy way to see your calendar .
If you still have one iOS device: You can share your iCloud for Google Calendar. You do not have complete control over each event, but you get the basics like title, time, and description of the event.
Go to the iCloud website and sign in with your Apple ID. On the main page, select "Calendar".
Click the Share icon next to the calendar you'd like to see in Google Calendar. In the pop-up window, check the "Public calendars" checkbox and click "Copy Link" under the URL.
Open Google Calendar now. Click on the plus sign on the left and then on the "From URL" option.
Paste the iCloud Calendar URL and click on the "Add Calendar" link.
You'll now receive a read-only ad version of your iCloud Calendar in your Google Calendar feed. This means that you can see your events without using an Apple device or iCloud.com.
