We build small, focused software for Apple platforms.
Zentsu LLC is a software studio working on native tools and apps for macOS and iOS. We favor private-by-default design, one-time purchases where the model fits, and shipping software that does a clear job without asking for an account.

How we build
-
Native first
Mac and iOS apps written in Swift and SwiftUI, not cross-platform shells wrapped around a web view.
-
Private by default
Our apps work without a Zentsu account or telemetry. When an app syncs, it uses your private iCloud storage instead of a Zentsu server.
-
Pay once
One-time purchases over subscriptions, where the model fits. The version you bought keeps working.
