Inside the app, programmes are listed by channel but also via genre. Recommendations, search, and parental guidance features are all included and you can also utilise Siri voice control. The BBC says subtitles are coming, as is the ability to find programmes via Apple's built-in search, but they'll be available in a later update.
The BBC is making good use of colour too, as the Cbeebies section (pictured below) demonstrates. It'll also play a big part in helping take BBC Three online-only, as the Beeb prepares to sunset the TV channel in February next year.
