Simple Contacts Lite is basically a lighter version of the more advanced version named "Simple Contacts", which is also available on the App Store.
Simple Contacts main purpose is to let the users try out the app before buying the paid one. Nonetheless, this app can be used to search, store, add, update or delete contacts in a simple, efficient and intuitive way. There is also a very simple way of backing up and/or restoring your contacts (in case you change your iOS device).
Most of the contact manager type apps available are too complex for day to day use. Simple Contacts does not get in the way of a user wanting to just search contacts, save and use contact information and keep the contacts backed up easily.
Please rate the app after using it.
Thanks.
