The BEST source to start learning German
In my learning history, I used probably the best website to start learning German.
That website is: http://leicht-deutsch-lernen.com/
Go subscribe to his email subscription, then go to basics. It should only take a few days if you work hard on it, and it builds a very strong base to your learning.
I still think Assimil is better.
That site looks like one of those shady websites that create dating manuals and whatnot, and end up being fake, poor quality, etc.
It's not a poor quality website at all. It's a ton better than any other website or app I've used, but only the basics and some featured lessons are free. I'd be fluent by now if it were all free.
