Come rain or shine, hell or high water you can be sure that App of the day will be at hand to bring you the best of the current app selection on a variety of platforms. Except on Sundays when AOTD has a day off and puts his feet up in front of the fire.

However this Sunday its not just going to be a case of lighting the fire but also lighting up our minds, as our AOTD brings the super-duper TED talks to the iPhone.

Previously an iPad favourite, TED for iPhone brings all sorts of interesting lectures from people that are at the top of their game, and the subject matter is truly diverse.

The app allows you to stream a whole host of TED talks in video or audio format and brings with it plenty that will be familiar to iPad users. Features include browse and share which brings up the latest TED Talks videos as soon as they're published; and all this can be browsed in the TED library by theme, tag or rating.

There is also a playlist function called "Inspire Me", which can build a tailored TED Talk list for you to listen to, just tell the app what kind of lecture you're after and it'll pluck out some likely candidates. All the lectures can be shared on Facebook, Twitter and over email.

There are two new additions to the app as well: a bookmarks tab enables listeners to save talks for later, whilst the TED radio brings a station full to the brim with TED Talk audio 24/7. Even better is that it will work when the app is closed down, so you can get on with other iPhone-related tasks.

In practice and the app works extremely well, with a clear and intuitive UI combined with some great content. This is pretty much a must for anyone interested in the world around them, and it's free to download now.
