SmoothSync for Cloud Contacts syncs your iCloud contacts. Due to its implementation as sync adapter it integrates seamlessly with the native contacts app and operates invisible in the background.
This app is bundled with Contact Editor Pro to allow you to edit synced contacts on pre-Android 4 devices. The app is designed to be as user friendly as possible. Just enter your account data and SmoothSync will keep your contacts in sync.
The app will not sync Contacts from other accounts (like Google) to iCloud!
