Somnus - designing better sleep habits

Research · Interaction design · Prototype

Problem

Sleep apps track data. None change behaviour.

Approach

Research → personas → competitive audit → prototype.

Outcome

High-fidelity concept with smart environment integration.

The problem

Poor sleep carries serious consequences, cognitive decline, cardiovascular risk, weakened immunity, yet the apps meant to help do little more than log data. There’s a clear gap between knowing you sleep badly and actually changing the habits that cause it.

What I did

I conducted user research and competitive benchmarking to understand why existing apps fail at behaviour change. A primary persona, Thomas, a stressed urban professional who can’t control his sleep environment, grounded every design decision.

From there, I moved through wireframing to a high-fidelity prototype, designing a personal wind-down ritual builder, adaptive sleep coaching, and smart environment controls (lighting, sound, thermostat). Gamification was introduced to sustain long-term engagement. Swipe-card micro-interactions keep the experience immersive without adding cognitive load at bedtime.
