One Page Website

We are building an app for Iphone, Android etc and would like a single page website to promote it.

We have instructed another freelancer on PPH to produce a short video, this will need to be integrated into the page.

Visitors to the site should also be able to download the app for either format dependent on their choice as well as viewing information as to what they can expect from the app.

We will also like a link for customers to browse conventionally online (this site will be built in the next few months)

We would like the webpage to be viewed easily on mobile devices, tablets as well as on normal browsers.

The app will not be ready until May but would like to get the design and functionality in place before then.
