The Bad Owl Tool App is Officially Live on iOS

The wait is officially over. For the past few months, our Android and Web users have been enjoying the ultimate digital woodshop assistant. Meanwhile, the iPhone crowd has been patiently (and sometimes not-so-patiently) waiting in the wings. Today, we're putting an end to the scrap-paper shop math: the Bad Owl Tool mobile woodworking app is officially live on the Apple App Store.

We built this app because generic calculators and clunky conversion tools don't understand the realities of a woodshop. They don't know the difference between a hardwood and softwood pilot hole, they don't care about wood movement, and they certainly don't know how to rescue a botched epoxy pour. We needed a digital wingman that actually works the way woodworkers think.

What Makes This App Different?

There is no shortage of digital fluff out there. We didn't want to build another gimmick. We wanted a pro-grade utility set that you reach for just as naturally as your tape measure or combination square. Whether you are batching out cabinet carcasses or dialing in the golden ratio for a custom credenza, this is what you get in your pocket:

Precision Shop Math

• Fractional Calculator: Featuring our Tape Snap technology, this calculator outputs actual tape measure fractions instead of useless decimals like 0.8125.
• Geometry Solvers: Side-Angle-Side and Angle-Side-Angle triangle calculators make complex layouts and segmented turning angles dead simple.
• Digital Levels: Bullseye and linear levels featuring custom zero baselines and individual surface calibration for real-world machine setup.

Lumber & Epoxy Calculators

• Board Foot & Species Estimator: Calculate exact board footage and get total weight estimates based on specific wood species. No more guessing if a wall cleat can handle the weight of that floating shelf.
• Epoxy Rescue Solver: Screwed up your Part A to Part B mass ratio? Don't panic. Our epoxy calculator tells you exactly what to add to balance the mix and save your expensive resin.

Machining & Hardware Guides

• Tap & Drill Helper: Not all wood compresses the same. Get precise drill bit sizes, clearance holes, and pilot hole recommendations specifically tuned for hardwoods versus softwoods.
• Bandsaw Radius Tool: Enter your target curve, and the app calculates the exact blade width, TPI, and kerf needed to make the cut without binding.

Birdbrain AI & The Apothecary

Need uncompromising advice, a custom finishing schedule, or project blueprints? Ask birdbrAIn AI, your new digital shop foreman. If you prefer old-school methods, dive into The Apothecary—a curated library of traditional recipes to mix your own shellac, natural stains, and hide glues with clear safety and difficulty ratings.

The Catch: Why is it Free?

Here is the absolute truth: we hate subscriptions, paywalls, and hidden fees just as much as you do. The Bad Owl Tool app is 100% free.

We fund the hosting, development, and constant updates entirely through the Bad Owl Tool online store. When you buy your router jigs, premium saw blades, digital angle gauges, and EcoPoxy from us, you directly support the app. It's a closed-loop system: we provide you with top-tier physical tools, and the revenue keeps your digital tools completely free. No corporate overlords, no annoying ads—just woodworkers supporting woodworkers.
