Bad Owl Tool App: Your Woodshop Wingman is Now on Android Native

We Upgraded Your Most Reliable Shop Jig

Let’s roll up our lab coat sleeves and get straight to the point. We’ve all been there: trying to do epoxy volume math on the back of a scrap piece of plywood, squinting at greasy drill bit charts, or guessing if we actually have enough board feet for that next dining table. That kind of shop math can seriously disrupt a good workflow.

That’s why we built the Bad Owl Tool app. You might already be familiar with our Instant Web Version that you can save to your home screen, but we are thrilled to announce that the ultimate maker app is now fully optimized and available as a native Android app on the Google Play Store. (Apple users, don't worry—your native iPhone version is dropping in Fall 2026).

It’s a free, no-nonsense digital toolkit engineered specifically for real woodworkers. Whether you’re a professional batching out custom cabinets or a dedicated hobbyist dialing in your first set of dovetails, we built this to solve the everyday bottlenecks. No fluff. No gimmicks.

What You Can Do with Bad Owl Tool

We didn't just wrap our website in an app container and call it a day. This is a dedicated shop assistant packed with tools to make your workflow seamless:

Milling & Dimensioning

• Board Foot & Species Database: Calculate board feet, estimate lumber costs, calculate project weights, and explore the properties of different wood species before you buy.
• Units & Fractional Converters: Instantly convert length, volume, and weight. We included multi-input fields and automatic fractional inch readouts so you can go straight from the screen to your tape measure without guessing.

Hardware & Joinery

• Tap & Drill Helper: Stop stripping screws. Find exact drill bit sizes, clearance holes, and pilot hole recommendations specifically tuned for hardwood versus softwood.
• Triangle & Angle Calculators: Quickly calculate missing side lengths and angles using Side-Angle-Side or Angle-Side-Angle modes. Perfect shop geometry, every time.

Specialty Shop Calculators

• Bandsaw Radius Finder: Calculate the minimum cutting radius for your blade, filtering by width, TPI, kerf, and material.
• Picture Frame Layout: Calculate side lengths, glass dimensions, rebates, and maximum frame sizes from your stock, complete with visual diagrams.
• Segmented Turning: Plan intricate bowls by calculating cut angles, segment lengths, and exact ring diameters.

Finishes, Adhesives & The Apothecary

• Epoxy & Finish Coverage: Accurately estimate resin volumes for river tables and finish coverage areas so you never run dry in the middle of a pour.
• Glue Finder: Compare PVA, hide glues, and CA adhesives based on open time and water resistance to choose the perfect bond for your joinery.
• The Apothecary: Access a curated library of traditional recipes to mix your own shellac, natural stains, and hide glue, complete with safety and difficulty guides.

Utility & AI

• Precision Levels: Bullseye and linear levels featuring custom zero baselines and individual surface calibration for real-world shop use.
