# Sofapps

We build apps. Get comfortable.

We design, build and look after our own apps, for the people who use them every day.

## Our apps for iPhone, iPad, Mac and Apple Watch.

## Our services.

What we learn making our own apps is available to companies and startups.

- **Consulting**: Idea, strategy and business model, before writing any code.
- **Design and development**: Native apps in Swift and SwiftUI, from scratch or starting from yours. No cross-platform frameworks.
- **Training**: Swift and SwiftUI courses and workshops for your team, from the basics to the architecture of an app.
- **Accessibility**: VoiceOver, Dynamic Type and increased contrast are part of the design from the first sketch.
- **Release and care**: TestFlight, App Store review and updates for every new version of Apple's systems.

## Made by people, on the slopes of Mount Etna.

Sofapps was born in Catania, a stone's throw from the most famous volcano in Europe. Behind every app is the person who thought of it and still looks after it.

Costantino Pistagna is a software architect and consultant. One of the first teachers of Apple's iOS Developer Academy in Europe, he has been building for the Apple world since the first iPhone was born in 2009. When he is not writing apps, he loves making sushi and travelling with his wonderful family.
