Counting kills consistency.
ZymFit was born from frustration: five years counting my macros in spreadsheets. The app started life as a lifting coach — before finding its true purpose: explaining a product's overall quality and how a meal fits your day.
I spent five years juggling tracking apps — one for calories, one for products, one for weight. None clearly explained a product's quality while placing a real meal in the context of the day. So I did what engineers do: Excel. 47 tabs. A file nobody else could open.
In 2024, I started coding ZymFit in Brussels, alone. The first version did everything: workouts, programs, nutrition. Too much. In 2026, I kept what it did best: explain a product's quality and place a real meal in the context of the day.
That pivot has a face: the chameleon. Its color makes the verdict readable, while the label always states the question: overall product quality or meal fit for the day.
Four principles. Kept at 100%. Not a manifesto to impress — a manifesto to live by.
- 01
Consistency over perfection
Meals logged in ten seconds, a streak that forgives a missed day (Pro freeze): everything is built for day 47, not day 1.
- 02
Data > Feeling
Scores out of 100 with their reasons, a smoothed weight trend and a weekly review based on reliable days. You don't guess whether you're progressing — you see it.
- 03
Simplicity > Features
The app has already survived its own big clean-out: everything that didn't help you eat better was removed. Every screen has a mission.
- 04
Honesty > Promise
The score is never a black box: public sources, visible reasons, limits owned. Product not found? Its code and optional photos go into a private manual-review queue — never straight into the catalogue.
A habit kept for 6 months beats the perfect plan dropped in 3 weeks.
In 2026, ZymFit is a nutrition scanner in 7 languages, on iOS and Android. The data comes from credited public databases — Open Food Facts, ANSES-Ciqual, USDA — enriched and verified by hand. Solo founder: every screen, every scoring rule, every comma comes from the same place.
Next up: more verified foods in more languages, an even faster shopping mode and an increasingly useful weekly coach. Two questions will remain separate: overall product quality and how a meal fits the day.
