Tesseract is currently under Apache License . If you are planning a commercial application, that means you should include a copy of the Apache license, and you display a copy of the required copyright notice wherever your program displays copyright notices.

Here is a link to someone who is using the engine in their android app. http://gaut.am/making-an-ocr-android-app-using-tesseract/

I followed this blog( http://tinsuke.wordpress.com/2011/02/17/how-to-cross-compiling-libraries-for-ios-armv6armv7i386/ ). It worked for me.
