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: a scanner that rates what you eat, for YOUR goal.
I spent five years juggling tracking apps — one for calories, one for products, one for weight. None of them answered the only question that matters at the moment of choice: “is this good for ME?” 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 made the call — cut it all, except the one thing the app did better than the rest: scan a product and answer in three seconds, with a score out of 100 calculated for your goal.
That pivot has a face: the chameleon. A mascot that changes color the way the score changes with your goal — the same product can be green for one person, red for another. It's ZymFit's founding idea, drawn.
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
A score out of 100 with its reasons, a smoothed weight trend, analyses of your last 30 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: an even sharper score (portions, context, history), more verified foods in more languages, an even faster shopping mode. And one bar that never moves: if it's not excellent, it doesn't ship.
