WoodPicker is a tool to simplify a woodworking project. You can use it to speed up the design, wood selection, and cutting steps of the project. Getting started on a woodworking plan is hard to do. Once you’ve painstakingly detailed a design, you need to select the best pieces of lumber to fulfill all the parts in the project and somehow keep track of each one. It’s not uncommon to spend hours at the lumberyard trying to figure out how to efficiently place the parts for your project on the best available picks of wood. WoodPicker is designed to greatly improve the experience of choosing lumber at the lumberyard so you can cut it into parts with minimal waste. With WoodPicker, you can now concentrate on picking the best lumber and be on your way in a fraction of the time. Here's how it works: WoodPicker will take your list of parts from your project plan and create suggestions of board dimensions to fulfill the parts list. If you can't find a board that matches the suggestion, no worries. Just change the suggested dimension and WoodPicker will automatically determine how to lay your parts on your chosen board. And when you've picked enough lumber for your project, WoodPicker will speed up your cutting time by providing a printable summary that illustrates the best layout for your project’s parts. If designing a project from scratch is overwhelming, WoodPicker also provides a growing list of project plans with illustrated cutting and assembly instructions that you can purchase to get you started even faster. All plans are FREE with the WoodPicker Pro in-app purchase. If you design your own plan in a program like SketchUp, you can easily import it into WoodPicker Pro with the CutList extension. Or, enter your parts list through the WoodPicker user interface. This requires the WoodPicker Pro in-app purchase. So whether you are a craftsman picking lumber for furniture or a weekend warrior with a backyard project, I’m confident that this app will speed up your job.

ReceptionRating · Positive reviews · Number of ratings

Carpentry Formulator holds the better App Store score, 3.8 against 3.0. That said, the two scores are not equally well evidenced: WoodPicker has 33 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 25% of Carpentry Formulator's written reviews are positive against 42% of WoodPicker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Carpentry Formulator ships an update every 2 months, WoodPicker monthly. The most recent releases landed on October 6, 2026 and September 18, 2026 respectively.
