PROBLEM
A fragmented cooking flow created friction.
Home cooks using both the thermometer and smart oven expected one seamless experience, but the app’s flow wasn’t designed for multi-device cooking.
Key problems:
No full control of oven from app
Inconsistent setup flows
Doneness selection came too late
No contextual guidance across proteins/cuts/appliances
Device owners expected more intelligence
Key Insight: Users didn’t want automation alone — they wanted clear, consistent guidance.
Original Cook Setup Flow
RESEARCH APPROACH
Understanding real cooking workflows from Whirlpool data and user testings
Research Activities:
Whirlpool partner research
5 early-concept tests
5 high-fidelity usability tests
WHAT WE LEARNED
Users needed a unified, predictable cooking flow
Four insights that guided the redesign:
Step-by-step > accordion
Big images ≠ better
Consistency builds confidence
Multi-device cooking must feel unified
EARLY EXPLORATIONS
Reorganizing cook setup for multi-device workflows
Guided by research insights around consistency, early decisions, and multi-device clarity.
What we explored:
Added “Cook Method” to support oven vs non-oven paths
Introduced contextual tips based on protein, cut, and doneness
Standardized layouts for protein and cut selection
Integrated smart oven controls (mode, cavity, temperature)
FINAL DESIGN - SETUP FLOW
A consistent, guided setup across proteins & appliances
What changed:
Earlier doneness selection enables smarter guidance
Predictable, repeatable layouts across proteins and devices
Clear branching for connected vs non-connected ovens
FINAL DESIGN - COOK SET UP SCREEN
A clear, step-by-step setup with guidance from the start
Setup emphasizes early clarity, then adapts based on available devices — ensuring users feel prepared before cooking begins
FINAL DESIGN - COOK SCREEN
Real-time tracking and oven control without leaving the cook screen
Monitor progress, adjust oven settings, and update doneness in one continuous flow.
