We build small, focused software for Apple platforms.
Zentsu is a software studio working on native tools and apps for macOS, iOS, and iPadOS. We favor offline-first design, one-time purchases over subscriptions, and shipping software that does a clear job without asking for an account.
Native macOS · In private beta, Mac App Store submission pending
A native macOS developer toolbox: JSON, JWT, regex, hashes, UUIDs, video conversion, and more, in one offline window. No accounts, no telemetry, no subscription.

Mac and iOS apps written in Swift and SwiftUI, not cross-platform shells wrapped around a web view.
Tools that work without an account, without telemetry, and without a server round-trip. What you type stays on your device.
One-time purchases over subscriptions, where the model fits. The version you bought keeps working.
We ship and iterate. We don't market with hype, and we don't add features we can't stand behind.
