Where can I watch teen wolf?

I've wanted to start Teen Wolf for a while, but can't find the show anywhere. It's been down from Netflix a long time, it's currently not available on Amazon Prime (?) And I don't know how safe that is for websites on the Internet. Could someone please help me there?

I also had the problem until recently because a friend of mine really wanted me to watch teen wolf haha.

There's an app called Rokkr and it's really good.

It's free and there are a lot of other series that you might not find on netflix or something like that
