What is this?

A workshop full of tools, in your pocket.

OneCut Shop is what we wish we had when we started woodworking. Every time we needed to figure out a miter angle for a segmented bowl, calculate how much epoxy to mix, or remember which dovetail angle works best for hardwood, we'd end up with seventeen browser tabs open and a notepad full of scribbled math.

So we built one app that does all of it. Not a SaaS platform. Not a subscription. Just a quiet, offline-first toolkit that lives on your phone or in your browser, and is there when you need it at the lathe, the saw, or the glue-up bench.

Why it's different read this
  • Offline-first. No WiFi at the lathe? No problem. Everything runs in your browser or on your phone.
  • No tracking. No analytics, no fingerprinting, no "anonymous usage data." Your projects stay on your device.
  • No ads, no popups. Ever. Even after beta.
  • One app, not 37. Tools share data — your shopping list pulls from your project, your timer talks to your glue-up guide.
  • Built for shop hands. Big touch targets, dark mode for the workbench, fractional inches for the woodworkers who think that way.

Who built this?

Built by woodworkers, for woodworkers.

We're a two-person team out of a Michigan workshop. One of us is a software developer who woodworks on weekends; the other runs a working finishing shop and puts the app through its paces every day on real jobs. We started OneCut Shop because we kept seeing the same gap: there are great commercial tools for production shops with five-figure budgets, and then there's nothing for the rest of us. The hobbyists, the side-gig builders, the one-person operations.

We've been building this in evenings and weekends for the last few weeks. It started as a segmented turning calculator (the very first module) and grew because we kept needing one more thing. Every time, we'd build it, put it in each other's hands, and ask "would you actually use this?" If the answer was yes, it stayed.

It's free during the beta. After beta, the offline app stays free. We're planning a paid cloud-sync tier for shops that want their data on multiple devices — but the core tools will always be free for anyone with a workbench.
