Fredoka

Fredoka is a geometric sans with every corner rounded off. The skeleton underneath is circular and monolinear — close to Futura in construction — but the terminals are capped with soft round ends, which removes essentially all of the severity that geometric sans faces usually carry.

The effect is friendly to the point of being childlike, which is precisely why it works for children's products, playful app interfaces, food brands and anything that needs to feel approachable rather than authoritative. It holds up at interface sizes better than most display faces because the underlying shapes are simple and open.

The flip side: it cannot do serious. If the brief involves finance, law or bad news, this is the wrong font.
