Made with craft and intention.

Brotto is an independent app development studio focused on creating delightful experiences for Apple platforms. Every app we build follows the same principles: beautiful design, native performance, and respect for your privacy.

Our entire development workflow is powered by Anthropic's Claude AI, from ideation and design to code and testing. We believe in building tools that feel like a natural extension of your device, not just another app on your screen.

Based in Brazil, inspired by the Araucaria forests of southern Brazil, our roots run deep in craft and quality.

Privacy First

We collect no data. Your content stays on your device, always.

Native Performance

Built with Swift and SwiftUI for the fastest, smoothest experience possible.

Thoughtful Design

Every pixel matters. We obsess over the details so you don't have to.

AI-Powered Development

Proudly built with Anthropic's Claude, pushing the boundaries of what's possible.
