S4C maintains its own catch-up service called Clic. Clic is a free online video on demand service which offers live-streaming, signed programming, a 35-day catch-up service, and archive programming. Clic is available across the UK but also contains a limited selection of worldwide programming. Clic's catch-up service is split into seven categories: Drama, Entertainment, Factual and Arts, Music, Sport, and two Children's categories, Cyw (ages 3–6) and Stwnsh (ages 7–13). A Clic app was released for Apple's iOS devices on 18 August 2011.
