Koto has partnered with Europe’s leading nutrition app Yazio to launch a comprehensive brand evolution, built to make good nutrition feel motivating, approachable, and genuinely enjoyable.

Yazio is a Germany-founded nutrition and calorie-tracking app built to make food logging simple, visual, and habit-forming, supporting weight loss, fasting, and everyday diet awareness. In a crowded, commoditised market, the brand risked blending in just as Yazio introduced a new gamified product strategy to drive habit formation. Yazio partnered with Koto to create an identity that could match this ambition and feel equally distinctive and engaging.

The strategy centered on Good Dopamine, repositioning Yazio as a feel-good companion that makes habit-building feel like a win.
