Found same question on another site (typophile), but no link. They say it's called Rockwell.
Linking through to another site I found the sketch version of this font type, which is (doh) called Sketch Block (also called Sketch Rockwell), made by Artill.
I'm not sure if I can link to other font sites, so I don't. Sry for that, but you should have enough keywords to find it yourself now.
Good luck Mahdi_Salah.
am so thankful for your effort iTinus
