Want to sync your Apple iCloud calendars, contacts, or reminders with your Android device? Since Android doesn't natively support iCloud synchronization, a third-party synchronization app is required. Once connected, aCalendar will automatically display all your iCloud data.

Recommended Sync App (DAVx⁵)

Important: aCalendar is not involved in data synchronization. The app acts purely as a user interface to your Android system's calendar storage. To safely bridge iCloud and your Android system, we highly recommend using DAVx⁵.

About DAVx⁵

DAVx⁵ is a secure, open-source sync client that hooks directly into the Android account settings. It runs reliably in the background to keep your iCloud calendars, address books, and reminders flawlessly synchronized with your phone. You can download it from the Google Play Store or alternative marketplaces.

Requirements: App-Specific Password

Because Apple uses strict security measures like Two-Factor Authentication (2FA), you cannot use your normal iCloud login password inside DAVx⁵. You must generate a secure app-specific token first:

How to generate it: Sign in to your Apple ID account page via a web browser (appleid.apple.com). Navigate to the Sign-In and Security section, select App-Specific Passwords, and click Generate an app-specific password. Give it a name (e.g., "Android Sync") and copy the generated 16-character code.

Step-by-Step Configuration

Once you have downloaded DAVx⁵ and generated your secure password token, setting up the synchronization takes just a few quick steps:

1

Add Account in DAVx⁵

Open DAVx⁵ on your phone and tap the plus icon (+) to add a new account. Choose the option Login with email address and password.

2

Enter iCloud Credentials

Enter your complete iCloud email address (e.g., yourname@icloud.com). In the password field, paste the app-specific password you created in step 2. Tap Login.

3

Select Your Calendars

Once DAVx⁵ connects successfully, name your account and tap Create Account. In the account overview screen, make sure to check the boxes next to the individual iCloud calendars you wish to see on your device.

View in aCalendar

Open aCalendar, open the side drawer menu, and tap Manage Calendars. Pull down the screen to refresh or make sure your newly added iCloud calendars are set to visible. They will sync automatically from now on!
