Interesting. The Smart Cover for the iPad 2 has certainly proven to be a popular add on. Mine still seems to get a bit dumber as time goes on, but it does still live on my iPad 2. I guess it was only matter of time before someone came up with an App that somehow worked with the Smart Cover and it looks like Evernote is the first to do so.
Evernote Peek is basically a curiosity, which is a good thing because it is free. Essentially if you open up the first flap of your Smart Cover with Evernote Peek running you get a little quiz question. You can connect this to your Evernote App and use the questions to create study guides, but I’m guessing folks will just have fun with this.
