How everything is made

A few rules, held without exception.

One problem, solved completely

Every app targets a single, specific pain and resolves it with no half-measures. If a feature can't justify itself, it doesn't ship.

Native Swift, no shortcuts

SwiftUI and Apple frameworks only. No Electron, no web views, no cross-platform runtime. Your Mac's hardware is used the way it was meant to be.

Offline by default

No accounts, no sync, no telemetry. The data never leaves your machine, because it was never designed to.

Pay once, own it forever

No subscriptions, no renewals, no features locked behind a tier. Buy it once and keep it for as long as macOS runs it.

Small enough to finish

Each app is scoped to ship in a few focused weeks. That constraint is the feature — it forces every decision to be deliberate.

Quiet by design

Most of these live in the menu bar or a right-click. They do their job and stay out of the way until the moment you need them.
