About Franco & zero.

Why I build and why 500 matters.

I'm Franco. I'm 13 years old and I code native iOS applications with Swift from Bolivia. I started zero. because modern software has lost its soul: apps are crowded with subscription paywalls, data harvesting, and dopamine loops.

I wanted to prove that quiet, honest software can still exist. That's why I created worth. (an anti-impulse buying companion that converts prices into real working hours of your life) and once. (a private daily photo journal with zero social anxiety).

The 500 Roadmap

  • 100 supporters: Official launch of worth. and once. on the Apple App Store. Early supporters receive promo codes with fees waived ($2.99 fee waived).
  • 500 supporters: My pledge: I will design, build, and publish 3 brand-new native apps 100% free for everyone forever.

Supporting takes 1 click with Google or Apple, zero fees, and no spam. It shows real people care about handcrafted, honest software.

Experimental optics engine and graphics renderer written in C++ and C. Computes signed distance fields (SDF), light bounces, and sphere reflections to output raw PPM images.

About Me

My name is Franco Senes Ricardo Calabi. I am 13 years old, building software from Bolivia 🇧🇴, and the founder of zero..

My technical focus is centered on native iOS architecture and Swift. Rather than superficial wrappers, I engineer end-to-end native applications—leveraging SwiftData offline persistence, WidgetKit interactive extensions, and fluid SwiftUI interfaces tuned for zero latency.

I built worth. to help people overcome impulsive spending by calculating true life-energy hours, and once. to create a private, unhurried daily photo ritual free of algorithms and social anxiety. In addition, I research graphics rendering, optics, and ray marching in C++ and C with RayGret.
