Building useful
Mac & iOS apps

Crafting focused, native apps that solve real problems — free to try, private by design, and built with Apple's own frameworks.

Apps

Four native apps for macOS and iOS. Every one is free to download.

How these apps are built

  • Native, not wrapped

    Written in Swift with SwiftUI and AppKit against Apple's own frameworks — so they launch fast, feel at home on the platform, and stay small.

  • Private by default

    Your data stays on your device wherever the feature allows it. Mactor collects nothing at all; Study Mood can generate plans entirely on-device.

  • Free to start

    Every app is free to download and useful without paying. Where there is a paid tier, it adds tools rather than unlocking the basics.
