Cabo Rounded is a sans-serif typeface with a minimalist style and rounded edges. Even though it has barely nothing to do with Helvetica, that was actually my whole inspiration for the font. The full typeface comes in 5 weights: thin, light, regular, medium and bold, each with an italic version.
The fonts you are getting in this demo, which are free for personal use only, are Regular and Italic.
It has full English alphabet, numbers, punctuation marks and a couple of accents.
