The Rolling Stones have launched their first ever app for iOS.
It's free to download, and claims to give fans around the world "unprecedented access" to the band, as part of their 50th anniversary celebrations.
You can unlock exclusive interviews and performances through the app, though it looks like you'll have to pay extra to receive these goodies. Fans can connect with each other and supposedly talk to the band themselves, preview new tracks for free, browse tour dates and check-in at gigs.
You can also win tickets to their upcoming tour, which could help you avoid paying the massive ticket prices which have had fans up in arms.
One interesting feature is how fans can vote for tracks to be played at upcoming gigs. It's not clear how many requests the band will take, but it's a novel concept.
"There'll be quite a few surprises in there for the fans," said guitarist Keith Richards. "Some behind the scenes footage, some old, some new stuff that very few people get to see. It's all part of a rather splendid celebration for us."
You can download the Rolling Stones mobile app from the iOS App Store today, though it may take 24 hours to appear in some countries.
