Introducing Zeitwerk - Time Tracking & Invoicing for macOS

Announcing Zeitwerk: Professional Time Tracking & Invoicing

We are excited to announce the release of Zeitwerk, our new macOS app designed for freelancers, consultants, and small businesses who value their time and privacy.

Why We Built Zeitwerk

As freelancers ourselves, we understand the challenges of tracking time across multiple projects and clients, then turning those hours into professional invoices. Most solutions either require cloud subscriptions, lack privacy, or are overly complex for what should be a simple workflow.

Zeitwerk is different. It’s local-first and privacy-focused — your data stays on your Mac, not in someone else’s cloud.
