Listos.app was created with a clear goal: provide fast, high-quality everyday utilities that anyone can use in 1 click, with zero barriers or account walls.
The internet is full of calculators and converters cluttered with deceptive ads, popups, and unnecessary registration gates. At Listos.app, we believe productivity tools should be instantaneous, clean, and accessible to everyone.
Whether you are a student counting dates, a freelancer calculating your weekly pay, or a designer converting iPhone photos, you should be able to get your task done in seconds and get back to what matters.
Your data, images, and calculations are computed directly on your own device using modern web APIs. We never upload or store your personal inputs on remote servers.
No signup forms, no passwords to remember. You visit the page, use the tool, and get your result instantly.
Every button and control is crafted for comfortable one-handed mobile use as well as smooth keyboard and mouse navigation on desktop.
Listos.app is designed and developed by Alexis Román Martínez, founder of Cabuya Creativa based in Puerto Rico 🇵🇷.
With extensive experience in web engineering and user experience design, our goal is to build digital products that balance technical excellence with an intuitive, human-centered feel.
Guided by this same philosophy of building practical, friction-free solutions, Cabuya Creativa is also the team behind Buen Turno ↗. If you are preparing for job opportunities or updating your career profile, we recommend checking out its online resume builder, designed with the exact same perspective as Listos: fast, private, accessible, and without unnecessary signups.
