naturally slim - redesigning mobile app experience.

Check it on App Store

Naturally Slim is a common-sense digital counselling program with more than 220,000 participants that teaches participants simple skills to change when and how they eat, instead of what they eat. It also helps with building other health habits leading to increased physical activity, better sleep, less stress and feeling more in control over health long-term.

our challenge.

Over 1/3 of program participant use the mobile app and are more likely to watch more videos which is a primary driver of revenue. Still, the old version of the app experience had significant usability and quality issues, which lead to blocking potential money for the company because fewer users wanted to use the mobile app at the end.

The goal of the project was to identify problems and possible changes which would lead to improving overall experience and increasing retention and engagement metrics.

However, while not creating a huge dev lift because the project was intended just for four months, counting development. We had to find as they say that "low hanging fruit".

what we did.

— Increased engagement in the video section by video-focused experience

— Improved retention of users using habit-forming, prompts and personalization

— Rethought logging meal process to increase user data investment and a better understanding of this main feature

— Improved usability and rethought architecture

testimonial.

While working with me on a number of client projects, Jakub quickly proved himself capable of carrying the ball and doing big things, solidifying himself as good friend, reliable colleague, inspiring creative, and valuable teammate. His youth brings a fresh perspective and a ton of passion. He has the ability to deliver work under pressure and on time at a level competitive with any junior designer I’ve worked with, and many mid-level designers as well. Anyone who has already collaborated with him knows that he is far ahead of the curve, and with his passion to learn and experiment, his growth will continue to impress and inspire those around him.

heuristics review.

Before modifying the existing design and digging into visuals and direction, we have decided to identify what’s working and what’s not from an interaction and usability standpoint through heuristics review.

A system wide review of the existing experience and architecture through the lens of 10 foundational principles of interaction and user experience design.

Main Issues:

— No onboarding, lack of education around features

— Lack of interaction and system feedback

— Inconsistency between shapes, shadows and colours

— Using the same components for different actions

— Not enough flexibility around changing after saving
