I thought this article was quite old. But then I looked at the date: 2nd of March 2015. The screenshots they used look dated though.
And they haven't included the best wireframing/mock-up tool: UXPin (imo).
I agree with alerise, above. I would be lost without my actual notepad. I also like using things like UXPin. There's a free trial on it- but if you'd like a free ten days, I can send you a trial link from my account; which would extend mine as well. Just a thought. Here's an article from Unpin, actually, that I liked; it has gotten me re-working all sorts of things, and learning a lot. Let us know of your progress and best of luck. Happy designing!
Best,
