Going through your requirement, we understood we will develop a IOS app which is an exact clone of a mapping android app. We have develop several apps and would love to do it.
After the app start, the homepage will get displayed. As mentioned by you, the homepage is done, so we will proceed with the next page. Now coming to the map, we will implement an routing algorithm to find the shortest path. The tiles will be customized and can be used in offline mode also. For this we will implement a cluster algorithm too.
We will also create a page for listing the point of interest along with the distance in sorted order as given in the snapshot 7in-near.png. A click on the map with display the path from the current location to point of interest location using the routing algorithm which we will implement. Further clicking on a listed point will display the detail information regarding it.
Now coming to the preference, where user can download the title, can also download files in the device and can clear the title cache. We will implement with a Synchronization setting option.
In the homepage, there is another option help, if user click on help then a Pdf file will get downloaded, which we will also implement.
After going through your requirement thoroughly, we have some doubts:
