Ayy.. nope. I don't make my own fonts (I don't have enough ideas to make one). I usually make typography quotes like those made in Tumblr. Graphic design is my hobby, not a profession. I'm still a student btw.

Microsoft can't use Helvetica because Apple is using it. If you read Wikia on an Apple device it's clear that the font used is Helvetica (by judging the tail in the small letter "a").
