Sound Scales

Baileys Sound Scales is a mobile app that solves the "how much is left?" question for Baileys bottles. Users blow across the bottle's top, and the app analyzes the sound's pitch to estimate the remaining liqueur. This physical-digital interaction unlocks content based on the level. Full bottles yield recipes, while near-empty bottles trigger discount codes, encouraging repeat purchases. The app enhances customer engagement by providing practical information and personalized offers, bridging the physical product with digital marketing.
