Font is diffirent on tablet/phone

I have changed my font in the css. I thought I was succesfull, untill I tried visiting my page by phone and tablet.

It looks like ipads use a very clasic curly font.. and my android phone is using a standard font like arial.

How can i make sure the font on the ipad is also readable?

I use the font on my website called Architects Daughter, wich is also a googlefont.
