The math kills the sport.
ZymFit was born from frustration: 5 years coding my own Excel spreadsheets to track my macros. At 25, I decided no one else should go through that.
I started lifting at 18. For 5 years I juggled between a dozen apps — each excellent in its own area. But opening 4 apps every day, with none of them talking to each other, is what pushed me to build ZymFit.
So I did what engineers do: I opened Excel. 47 tabs, 12 formulas, and a file that crashed the moment a friend tried to look at it. I tracked my macros to the gram, but I dropped the program in week 4. Not from a lack of discipline — from a lack of tooling.
In 2024 I started coding ZymFit. The idea: a single app that takes the math, celebrates the effort, and makes consistency visible. Not one more. The right one.
Four principles. Kept at 100%. Not a manifesto to impress — a manifesto to live by.
- 01
Retention > Acquisition
We'd rather 1,000 users who stay 12 months than 10,000 who leave at 3 weeks.
- 02
Data > Feeling
Don't know if you're progressing? The app tells you, numbers in hand.
- 03
Simplicity > Features
Every screen has a mission. We remove before we add.
- 04
Honesty > Promise
No AI coach writing fake messages. No generic program branded “personalized”.
A program held for 6 months beats a perfect program dropped in 3 weeks.
In 2026, ZymFit is available in 5 languages: French, English, Spanish, Portuguese, German. Native iOS and Android. Build after build, we raise the bar.
In 2027–2028, we keep going. Contextual AI coaching (not generic). Human coach integration for Pro. Marketplace of community programs. But above all: we hold the bar. If it's not excellent, it doesn't ship.
