We need a mobile app (at first an iPhone app) for our existing free datingsite.

The app should be downloaded for free and people should be able to login to their existing profile or create/register a new profile with the app. The registered people online (normal existing website) should also be able to log in into their existing accounts.

Further more members need to be able to do basic searches in the database and browse through a list of results. Clicking on a specific profile should show a basic overview of the profile of that found member. This basic profile shows 1 or more pictures (thumbnails with the option of seeing a bigger photo) and some basic information about the profile of this member. People also need to be able to send messages to the found profiles/members.

As this is a free website the usage of the app should also be free. So no payment-interface needs to be implemented.
