The app has a minimalist user interface, with a station - day - show descending navigation system, which makes it fast and easy to find the show you want to listen to. Each show gets a page with a thumbnail, an audio player with basic controls (play/pause, fast forward, and rewind), a short description, and a link to the shows associated web page (for further information).
Listen Again is available in international markets, but do note that some of the BBC's audio stream and region restricted. Some, however, are not, which as the app's Window Phone Store descriptions, makes Listen Again "ideal for expatriates missing their favourite programmes".
Windows Phone Store description:
This app lets you listen to BBC iPlayer radio streams over WiFi or 3G cellular networks. It does not show video.
You can listen to almost all programmes from the previous week. This includes programmes which are not available as podcasts. You can browse programmes by the day they were broadcast on, or you can browse episodes by series.
Listen Again is a free download from the Windows Phone Store.
