Giovanni Palusa · iOS developer · Stockholm
I build apps that keep to themselves.
I’m Giovanni, an independent developer in Stockholm. Since 2017 I’ve built native apps for iPhone, iPad, Mac and Vision Pro in Swift and SwiftUI, lately with on-device Apple Intelligence. Your data stays on your device.

What I do
Native apps, from first sketch to the App Store.
I design and build the whole thing myself: the idea, the interface, the code, the backend when one is needed, and the release.
On-device AI
Features built on Apple Intelligence and the Foundation Models framework, like trip planning in Map My Day. The model runs on the device, so nothing leaves it.
Tools and open source
Swift packages, a Mac app and command-line tools, shared on GitHub when they can help someone else.

Map My Day
A private, automatic travel journal for iPhone, iPad and Vision Pro. Replay any day hour by hour, earn explorer badges and plan trips with on-device AI.
Blixtra
Live lightning, precipitation radar and thunderstorm forecasts across Sweden, with strike details, replay and alerts near the places you care about.
Screenshot Studio
An offline Mac editor for App Store and Google Play screenshots on one shared canvas, in every language. Free and open source.
Open source
Small tools, shared.
Things I built for my own projects and published in case they help yours.
ShakeLogKit
Surfaces your app’s logs in a SwiftUI sheet, triggered by a shake gesture or a button. Built on OSLog, with filtering and search.

// The spring of an animation, the wording of a

// hardware and 3D printing.I started building for Apple platforms in 2017 and founded my studio, Palusa, in 2018. These days I spend most of my time on Swift, SwiftUI and on-device AI, and on apps that respect the people using them.
