Scope
Redesign of a live web MVP, then native iOS and Android
Role
Lead Product Designer (UX/UI) - NozomiHealth
Team
11 people - the largest engagement of the portfolio

The SUMU project is a mobile application whose purpose is to analyse a person’s sports nutrition and wellbeing, and to generate advice from it - to improve health, wellbeing and longevity.

The partners had a web MVP that worked and still missed its goals. Wrapping it for mobile would have shipped sooner and changed nothing: the problems were in the flow, not in the platform.

Situation

A product with users, and goals it was not reaching

An existing web MVP was live and falling short of what the partners wanted from it. What they asked for says where it hurt: daily engagement, onboarding, navigation, and the flow through the product.

The brief was a redesign followed by native iOS and Android development - rebuilt rather than wrapped. Eleven people across product, design and engineering, the largest engagement of this portfolio.

Method

How it was done

  1. 01

    Found the pains before redrawing anything

    Existing user pains and analytics first, then custom user tests built for this product - the flow and the pain points were located, not assumed.

  2. 02

    Rebuilt the UX

    Flows, prototypes and interactive tests, with onboarding and navigation restructured against known patterns of the audience rather than against the old screens.

  3. 03

    Rebuilt the UI

    Grid, the three-colour rule, the three-click rule, honest clickable areas. The constraints were the point: they are what makes a health app readable at arm’s length.

  4. 04

    Added illustration and a character

    A guide character carried the gamification, so that progress had a voice instead of a progress bar.

  5. 05

    Tested locally and iterated

    The prototype went through usability testing before and after the redesign, and the findings went back into the design.

Results

What the tests said

Success here was measured as engagement and brand recognition, through usability testing before and after the redesign - a different metric set from enterprise finance, and worth naming as such rather than hiding.
