Plinth Rounded

Plinth Rounded is a geometric sans with softened terminals and circular dots. Six weights with italics cover Latin extended and Vietnamese, and an educational set offers single-story a and g, plus clearer 4 and 9 for early readers. A variable version spans the full weight range.

It suits children's apps, learning platforms, health and wellness products, and any brand that wants to feel approachable without looking childish in the regular set. The $45 license covers 2 desktop seats, web use and one mobile app. The caveat: the rounded shapes make it wider than most UI fonts, so expect fewer words per line than you're used to.
