This app allows you to view the recent and previous calls you have received, calls you have missed, etc. This is an application to store your call history forever, without having to download any other app. It does not save the content of your phone's storage, but it has a simple user interface that makes it easy to browse your calls in different categories, such as history, missed calls, outbound, and inbound. You can select multiple categories to export them all to one file.

The app is extremely easy to use.
