Contacts Backup & Restore will import, export, back up and restore contacts saved on your iPhone with the tap of a button. It is a quick, easy-to-use app in many ways; and as a result, if you find yourself losing contacts during upgrades or other operations, it can be a useful tool to have on hand.
Contacts Backup & Restore doesn't require you to sign up or create an account to store your contacts in the cloud. It seems to back up directly to your device, though you can also export in any number of formats directly to your device to send to a cloud storage account or another device. Every operation is on one screen and they all run very quickly. While the app does not offer contact management in much of any form, the backup, restore, export, and import options are all very fast, and there are no restrictions on the number of contacts you can move or restore to your device with the free version.
If you need a single-function app to back up and restore contacts on your iPhone, then Contacts Backup & Restore will get the job done. This app is not designed for power users who need a more robust contact manager or editing tool; it is for those who have a large contact list and want to ensure it stays backed up on a regular basis. For this single but important function, it is a fantastic tool and a great addition to your library.
