About this app

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.

Also, check out SmoothSync for Cloud Calendar to sync your iCloud calendars!

Samsung S5 users: Please note that some S5 devices come with a broken contacts app that crashes when opening a contact synced by this app. Please report any crashes to Samsung.

Important note for Android 4.1 and Samsung users: To prevent the removal of your accounts on reboot install this app (before you install SmoothSync):
As of Android 4.2 this issue is fixed and the workaround no longer necessary (except for Samsung devices), please uninstall it.

HTC One users please check out this site first:

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!

Please, if you find a bug send me an email. Without detailed error description I often can't do anything especially when I can't reproduce it.

Important! If your phone removes the accounts on reboot, move the App back from SD card to the phone. Some phones (if not all) can't handle sync adapters on SD Card properly. Also check if you need the workaround app mentioned above.

Thanks to the guys at for their support!!

I have used this app for a few years and it has been very useful in syncing my icloud contacts to my android phone. Several days ago it stopped working! I now get an error message "An error occurred" every-time the phone attempts to sync. The result being my contacts have been removed from my android phone. . I logged a support docket with the developer but have not received a reply. In the absence of a reply/fix I can not recommend smoothsync for cloud contacts Update: The Developer of this software offered me access to development version of Smoothsync for icloud. Whilst the software is still "Work In Progress" it is effectively syncing my schedule, contacts, and tasks.Well done!

Have used this app with others from the same developer for years. Been getting an error like other users for several weeks. The developer acknowledged the issue but wasn't sure when a fix would be issued. A shame as I'm now having to look elsewhere for alternative solutions. Update:27th Mar. Followed the advice of others & switched to Smoothsync for icloud which seems to work. Would of been nice for the developer to have suggested this the first time I contacted them. If this app is no longer supported or functions it should be removed from the store.

Was an amazing app, had it installed for about 5 years and no issues. A few days ago I started getting error messages. Submitted them to support. Emailed support no response at all. What a shame cause when it worked it was great. Not sure what to do now.
