Independent developer · Sweden

I build private,
thoughtful apps
for Apple platforms.

I'm Giovanni Palusa, an independent developer in Sweden. Through my studio, Palusa, I've spent years crafting native Apple apps that put your privacy first and sweat every last detail — built in Swift and SwiftUI, and increasingly powered by on-device Apple Intelligence and the Foundation Models framework.

Blixtra

See the storm as it happens

Follow lightning across Sweden in real time on a beautifully clear native map. Explore each strike, watch precipitation radar, look ahead with thunderstorm forecasts, replay recent activity, and get alerts when lightning moves near places you care about.
