🚀 The Challenge
With three young children, white noise became a nightly ritual in our home, something that traveled with us wherever we went. I wanted a simple and reliable app that could play soothing loops of bedtime sounds across any device. At the same time, I saw an opportunity to learn Flutter, Google’s cross-platform development framework.
The goal was to build an app that could serve both as a useful tool for my family and as a design and technical experiment that would stretch my creative and engineering skills.
🎯 Objectives
Develop a cross-platform Flutter app for iOS and Android
Deliver a minimal, soothing interface optimized for nighttime use
Establish a playful, distinctive brand identity within the crowded sleep-app space
🛠️ Our Approach
The project began with personal need and curiosity, turning a family-driven idea into a creative laboratory for design and development.
The design vision centered around ease, calm, and warmth. I explored deep purples and midnight hues to create a screen experience that would be comfortable in dark environments. The typography followed that same spirit, rounded and approachable, pairing perfectly with the app’s tranquil purpose.
As the visual language evolved, I introduced a recurring character: a small astronaut peacefully floating through space. The figure added a sense of narrative and whimsy, while the cosmic gradients created a dreamlike atmosphere that reflected the app’s function and mood. Each track illustration became its own miniature world, helping the user feel calm and immersed as they browsed different sounds.
💡 The Solution
The final identity, seen in the Blanco logo and interface, embodies calm playfulness that feels both serene and imaginative.
The wordmark uses a softly rounded script font that feels hand-drawn and personal, evoking the comfort of bedtime stories and the warmth of a parent’s voice. Each letter has a subtle bounce and looseness that gives the logo gentle movement, as if floating through space and mirroring the app’s dreamy theme.
The crescent-moon “C” serves as a visual wink and immediate symbol of nighttime rest. Its glowing gradient ties back to the celestial palette and reinforces the tone of quiet wonder. Together, the typography and mark project a tone that is friendly, whimsical, and soothing, yet polished enough to feel premium in digital storefronts.
The color palette of lavender, violet, and cosmic blue deepens the night-sky narrative and evokes the serenity of deep sleep. The astronaut motif completes the story, drifting peacefully through a galaxy of sound and reinforcing the brand’s purpose as a calm and imaginative companion for bedtime.
The resulting visual system strikes a balance between family-friendly charm and design sophistication, standing out as approachable and refined across mobile screens.
