ddApps

Privacy-oriented software,
built to last

ddApps is the independent studio of Dulio Denis, a software engineer in New York City. After a decade of designing and shipping iOS apps, first in Objective-C then Swift, the work today is accelerating and more deliberate. Products engineered in SwiftUI and Zig, and built around a simple philosophy: software needs to give you super-powers, respect your attention, and protect your privacy.
