very simple, rounded, sans serif font family

 The Dosis font comes in 7 incremental weights:
 ExtraLight, Light, Book, Medium, Semibold, Bold & ExtraBold.
 The lighter weights are minimalist. The bolder weights have more personality.
 The medium weight is nice and balanced. The overall result is a family that's
 clean and modern, and can express a wide range of voices & feelings.
