How we build

Four principles behind every app.

  • Native First

    Apps should feel at home on the platform they run on. On the Mac, that means Swift, SwiftUI, the Human Interface Guidelines and proper accessibility support.

  • Privacy First

    Your data belongs to you. Collect less, explain more, and process locally whenever possible.

  • Practical Over Clever

    Solve real problems before adding complexity. One useful feature is worth more than ten impressive ones.

  • Polish Matters

    Performance, stability, accessibility and documentation are product features, not extras.

About

Independent, on purpose.

FourCav Software was founded by Zach Taffet to build a small collection of Mac apps that people trust, enjoy and recommend.

Success is measured by product quality, customer satisfaction, sustainability and independence, not by growth at all costs. That leaves room to keep the software simple and careful with your data.
