As featured in This Old House Magazine: "A must for us."

The Woodshop Widget is a rich collection of wood-related utilities, ranging from board volume calculation to shellac mixing aids, squareness testing and many other goodies. It is useful in woodworking as well as in DIY and construction/contracting projects. It contains a wide range of functionality that handles many tedious tasks simply and clearly.

The Widget understands Imperial and Metric, and the local measurement system for your iOS device is used by default. You can change this at any time with the app settings. It also uses a custom keyboard for quick access, making editing both efficient and immediate.

Be sure to check out the online companion site, which includes all of the same features, at!

Shows an estimate of how much a board might grow and shrink under different conditions, based on verified information for over 270 distinct species. You can enter measured or humidity-based water content, board width, and how the board was cut from the tree (anywhere from flat to quartersawn). The amount of change is shown as you edit.

Board Volume
Easily enter the 3 dimensions required for calculating board volume and get an immediate amount. You can also enter a price and quantity of boards for a total price. The local currency is automatically used when entering prices.

A species comparison tool that lets you walk through information on up to 288 species of wood, comparing hardness, density and movement. It even shows you which species is "better."

Compound & Crown
Create compound miter cuts with any combination of angles! Cuts for crown molding, cupolas and sloped boxes have never been easier to make.

Decimal to Fraction
Enter fractions and see the decimal results, or enter decimal values and see fractions calculated, all in one place. Remainders and reduced fractions are automatically shown.

A species data viewer which also includes "other names" for up to 288 species.

Mix or dilute shellac in any amounts. Enter a "pound cut" and the measurements are balanced for you. Mix as much or as little as you need, using not only gallons and pounds, but also cups and ounces or liters and milliliters. Dilute from any pound cut that you have on hand to any other concentration, instantly!

Test your framing squares, combination squares, carcasses or anything else that needs a perfect right angle for accuracy by measuring lengths. The Widget will show you how far from "right" the angle is.

Good app, however...

This is a nice app and usability is pretty intuitive. One thing that is super frustrating is the board volume calculator. It works well at first use and allows you to determine expected costs at the lumberyard by calculating board feet, based on advertised price per board foot. The frustrating part is making adjustments when, say, you're calculating costs of different species.

You would think that you would put in your dimensions and then just change the price per board foot for the different species, but if leave the app, get a phone call, turn you phone off or your phone goes to sleep mode, all of the dimensions reset and you're left with having to put all that info in again. Sounds minor, but super frustrating when you're trying to do calculations even within a 10-15 time frame.

I hope that can be fixed in future versions. Otherwise, still a decent app!

Problem with dimensions resetting

While checking wood movement I had to constantly watch the board width because it would default back to 6” randomly.

Good little calculator but the quirks make it too risky to use regularly.

Fix the dimension resetting problems and you’ll have a great app.

Fantastic asset to any woodworker

Can't say enough good things about this app. Easy, clean interface, great tips that are updated regularly and the board foot calculator and shellac mixing calculator are invaluable. I work in a woodworking store and it's nice to have a quick answer when a customer who doesn't understand board foot pricing asks me, "How much does this board cost?" Never fails to impress when I whip out my iPod Touch, punch in the numbers and show them the cost of the board. This app is aces 10!
