Best Free Android Notes App?

I'm pretty new to the whole notes thing.

Have just started to use Evernote, and I really like it but also need some sort of password protection that without going down the premium route (don't think I'll use it enough to justify that) doesn't seem possible.

But is Evernote (non-premium) as good as it gets when it comes to free notes apps? Or is there something that offers more features such as password protection/encryption for individual notes?

Thanks!
