Federico Trevisani

Independent Apple Developer

Careful craft.
No shortcuts.

I'm Federico Trevisani, an independent developer in Italy. I design and build software that feels natural and reliable across the Apple ecosystem.

That means embracing native technologies with discipline: SwiftUI, SwiftData, HealthKit, Apple Watch complications, CarPlay, and on-device intelligence whenever they genuinely enhance the experience.

Purpose first: Every feature exists to solve a real task in as few steps as possible.
Privacy by design: Your data stays on your devices and in your personal iCloud. Zero intermediaries, zero tracking.
Agency and clarity: No black-box algorithms or irreversible actions: you always maintain complete visibility and control.

Let's connect.
