Newsstand allows iPad, iPhone and iPod Touch users to find digital newspapers and magazines in the App Store and organise them on one bookshelf.
Last week the publishing house announced 55 mix of free, paid-for and premium titles would be available via Newsstand.
In a statement the company says the two million downloads “represents consumer spending well in excess of normal monthly revenues.”
Available titles include Total Film, Classic Rock, Metal Hammer, .net, Edge, Procycling, Digital Camera and Xbox 360: The Official Xbox Magazine.
Future UK CEO Mark Wood says: “Future had sold more digital editions in the past four days through Apple’s Newsstand than in a normal month. It’s clear that Newsstand creates an amazing opportunity for publishers – and I’m committed to continue driving our brands through this great new distribution channel.
“We plan to include more sampler issues in every magazine container in coming weeks, as well as uploading high price-point bookazines and premium one-shot titles.”
