About Carl
Carl designs the screens and writes the code. He uses macro like everyone else — at the end of a long day, with food in front of him, wanting to log it in seconds.
Carl Rosales
Founder & Developer
Tracking your calories and macros shouldn’t feel like homework.
At macro
When something feels slow or confusing, he notices it first — then he fixes it.
He'd rather leave a feature out than ship something you'll hate opening.
What Carl works on
Product & Design
The app should be easy even when you're tired. If you have to stop and figure it out, Carl isn't done.
Engineering
Fast, private, and works without internet. He builds it as if your meals were on his own phone.
Strategy
He keeps macro focused on what actually helps you log. Macro stays small on purpose — so it stays a habit.
Craft
The tiny stuff: haptics, spacing, the way a photo lands. That's the part he can't leave alone.
