As all others demanded here: lease bring back tabs and multiple windows! absolute key feature!!!!

For Android devices, there is an App doing spaced repetition integrating Evernote:

http://www.revunote.com

Unfortunately not for iOS. 

I asked the guys at Revunote whether an iOS version is planned but I had to learn that this is not the case.

Hi there,

I´d like to contribute another alternative for using spaced repetition learning with Evernote:

I use the App Anki for spaced repetition learning: http://ankisrs.net

It´s free and open source.

There´s an easy way to link an Anki flash card to an Evernote Note:

If you on Mac the HMTL string shown in this video for the link can easily applied by using TextExpander.

Hope this helps!
