Context

Closing the mobile gap for a €510M brand

€510M in annual sales with zero mobile presence. M-commerce was already the dominant channel — Cecotec had no way to reach users on mobile.

The Challenge

“How do you design a first mobile app that doesn't just replicate the web — but builds active loyalty with the user?”

Impact

Results

A validated, dev-ready prototype grounded in real user behavior — not web assumptions.

0

Unresolved Frictions

Every hierarchy, accessibility, and CTA issue resolved before delivery.

7

Usability Testers

Validated across all 3 personas — purchase, tracking, search, and CecoClips.

4

Validated Flows

Purchase, tracking, search, CecoClips — dev-ready with Atomic Design system.

Key insight: Card sorting showed mobile users group by lifestyle context — so the entire IA was rebuilt from scratch rather than copied from the web.

Double Diamond — Design Process

Four phases, one validated prototype

01

Discovery

  • Surveys and semi-structured interviews to map user behavior, purchase motivations, and pain points
  • Analysis of Cecotec web user journeys to identify mobile-specific value moments
  • Mapped the purchase cycle to find where a mobile app creates unique value over the web

Output

Mobile app adds unique value in reordering, tracking, and loyalty — not just a web port.

02

Definition

  • Benchmarking against leading e-commerce apps (Amazon, Zalando, Leroy Merlin)
  • Non-moderated card sorting: 3 groupings emerged — Home & Appliances, Fitness & Personal Care, Home Maintenance
  • Definition of 3 user personas: Ejecutiva Exigente, Comprador Técnico, Usuario Tradicional
  • Feature prioritization matrix balancing user need, business value, and technical effort

Output

IA validated against real mental models — 3 card-sorted navigation categories, not replicated from the web.

03

Development

  • Low-fidelity wireframes for all primary flows
  • Atomic Design system: Atoms → Molecules → Organisms → Templates → Pages
  • High-fidelity prototype covering all 4 product pillars
  • Accessibility and visual hierarchy review across all screens

Output

Complete high-fidelity prototype covering purchase, tracking, and CecoClips flows — ready for validation.

04

Delivery

  • Moderated usability test with 7 participants across all 3 personas
  • Friction in hierarchy, accessibility, and key action prioritization — all resolved before delivery
  • Final Atomic Design system with annotated specs for development handoff

Output

All identified frictions resolved before delivery. Zero open issues at handoff.

User Personas

Three profiles, one consistent experience

3 distinct personas drove every design decision — from tap target size to navigation depth.

👩‍💼

Ejecutiva Exigente

Busy professional. Judges the app by how fast she can reorder or track a delivery.

Priorities

🔧

Comprador Técnico

Researches before buying. Needs complete specs, reviews, and comparison tools.

Usuario Tradicional

Less experienced with mobile. Needs large tap targets, simple navigation, no surprises.

Solution

CECOApp — four pillars

Structured around four core pillars addressing the full lifecycle from discovery through community.

🔍
01

Product Discovery

Personalized home feed, card-sorted category browsing, and smart search with filters.

🛒
02

Simple & Efficient Purchase

Streamlined checkout, saved addresses and payment methods, one-tap reorder.

📦
03

Real-Time Order Tracking

Live status, estimated delivery, push notifications. No need to contact support.

🎬
04

CecoClips

Short videos from real users showing products in use. Built for retention and loyalty.

Design Decision

What we didn't choose

Replicating the web structure was the fastest path — and was explicitly rejected.

Card sorting showed mobile mental models differ from desktop. Clarity over consistency.

Discarded

Mirror the existing Cecotec web navigation structure for the mobile app architecture.

Chosen

Design IA from scratch based on 3 groupings from non-moderated card sorting with real users.

Why it mattered: Mobile users browse by lifestyle context, not product taxonomy. The web was optimized for SEO — not for how people think.

Reflection

Key learnings

Mobile-first means redesigning around the mental model shift that happens when users pick up their phone. Not making things smaller — making them different.

The most important research method was card sorting, not interviews. Users couldn't articulate how they wanted to navigate — but the sort data showed it clearly.

Data beats assumptions about navigation

Card sorting with real users produced 3 clear groupings that contradicted the existing web taxonomy — and became the entire IA.

Usability testing is not optional

7 participants across 3 personas found real friction in hierarchy and CTAs. Those fixes made the difference between a prototype and a usable product.

CecoClips was the loyalty differentiator

Short videos from real users create reasons to return that a product catalog alone can't generate.

Atomic Design pays off at handoff

Building from atoms up meant the design system was the handoff document — no extra annotation needed.
