For professional tools, 'playful' doesn't mean bouncy animations or emoji-laden copy — it means the app visibly cares about the user's experience. Hydrolyze resolved its tension between 'information-rich effortlessness' and 'playfulness' by keeping the clinical text (HYDROLYZE, LAP, READY) and putting all the warmth into responsiveness: haptics, spring physics, idle breathing on CTAs. The rule: playful lives in how the app responds, not in what it says.
