The app first launched in April for the but version 2.0 brings support for smaller iOS devices.

It's free to download and content is free, though you will need to be connected to a Wi-Fi network to watch video content. You can browse through the app on a 3G connection, though.

There's also a new search menu and should you want to keep programmes forever some of them are available to buy via iTunes through the app.

Ryan Hall, joint managing director of Nice Agency, which created the app, said: "The whole point of having 4oD in your pocket is to give users access to their favourite Channel 4 content, whenever and wherever, they are. It shouldn't take more than a moment to engage with the 4oD Catch Up app, browse your desired content and start watching.
