Hot on the heels of Adobe's recent announcement that Creative Suite is going to get a lot more cloud, it's made Adobe Ideas, a vector-based drawing app for iOS, absolutely free.
The app also received a hefty update, adding several of the Creative Cloud features announced yesterday and a slew of new brushes. Of course, there's also a few new in-app purchases to unlock full pro-level functionality, but the app was £7 yesterday, and now it's free. And if you bought it in the past three months, you can get a refund here. [iTunes]
