The Problem

Dieting apps were
restrictive and discouraging.

Existing apps told users what they couldn't eat. The flexible dieting method (IIFYM — If It Fits Your Macros) offered a more sustainable approach — but had no well-designed consumer product.

The Problem
Approach

Tracking food should feel
like progress, not punishment

Ran user interviews with people who'd tried and abandoned diet apps. Found that shame-based design was the core drop-off trigger. Redesigned around progress and momentum.

Approach
Design

Flexible targets, clear
progress, zero guilt

Designed a macro-based tracking system with daily and weekly flexibility. Added a "remaining" view instead of "consumed" — a small framing shift that dramatically improved how users felt about the app.
