Four apps. One quiet philosophy.

The apps

Four tools. One philosophy.

Each app does a small job exceptionally well, then gets out of the way the moment you're done.

Live on the Mac App Store LogicDesk

LogicDesk

Four tiny tools in one quiet window — instant AI answers, tasks, today's calendar, and frictionless capture. Hit a hotkey, get what you need, move on. (Formerly Quattro — the App Store listing still shows that name during the rename.)

What? Next. When. Dump.

LogicTray

A native Mac app that triages your mail with AI — it bundles what's alike, flags what actually needs a reply, and drafts responses in your own voice.

LogicVoice

A voice power-tool in your menu bar. Speak a command — it becomes AppleScript and runs, with the script shown and anything risky confirmed. Plus a dedicated dictation mode for any app.

LogicContent

A marketing operating system for indie developers — a weekly task queue, one-click content fan-out from your changelogs, launch kits, and a log of what actually works.

The approach

An indie dev, a Mac, and one quiet idea.

HandLogic is the studio behind the kind of Mac apps I wanted to use myself — small, fast, native and quiet. No chat sidebar that won't go away. No agentic monster trying to run my life. Just sharp tools that share one window, the way Mac apps used to feel.

The Mac apps are built native-first with SwiftUI — native materials, your system theme, fast launch, almost no memory. Your data stays yours across every app: bring your own AI keys, no analytics SDKs, no telemetry, no ads. Shipped from Brisbane, Australia.
