Nearly 25 billion apps have been downloaded from Apple's App Store since July 2008.

That's quite a lot, and Apple is understandably keen to celebrate this milestone sales figure.

Luckily for us, the Cupertino company has decided to mark the occasion with a massive giveaway, rather than just an office party.

The prize on offer is a $10,000 App Store gift card, and it could be yours if you're the person to download the 25 billionth app.

Or you could just fill out this form on Apple's website for a chance to win.

If you want to keep an eye on the running total, perhaps in the hope that you can swoop in and bag the 25 billionth download, then you can do so here.
