It was made available on December 17 and was removed Tuesday morning.
The app that cost $1.99 for information available for free online allowed users to peruse the controversial, secretly leaked documents as well as follow the site's Twitter account.
Apple told Silicon Alley Insider: "We removed WikiLeaks because it violated developer guidelines. An app must comply with all local laws. It may not put an individual or target group in harms way."
Other large companies have distanced from Wikileaks -- among them Bank of America, Visa, PayPal, MasterCard and Amazon -- so Apple is not alone in its disdain.
