Commuters, travellers and those afraid of the adverse effects of data signals on their brains will be happy to learn that they can now download Channel 4 shows through the iOS and Android apps.

That's right, offline caching has arrived so you can enjoy all those 24 Hours in A&E and One Born Every Minutes in all their glory underground, overground and in reception black-spots. Rejoice.

4OD will be hoping that the new feature proves as popular as a similar offering from the BBC's iPlayer.
