## What is WoodworkerCalc?

WoodworkerCalc is a specialized calculator for fine woodworking and other crafts. It makes it very easy to enter and perform calculations on measurements and tracks errors that can accumulate during layout. When laying out repeating units, a small round off error in the fractions can result in large errors. WoodworkerCalc displays these errors so the layout accommodate them.

It is easy to go back and forth before decimal and fractional results. You can choose the precision of the fraction to reflect real-world working units. For example, 1/32 is the typical smallest unit used for woodworking layout.

Calculations are stored on “tapes” which can be saved and restored later. This allows sequences of calculations to be preserved for later use.

There is also a board foot calculator which is useful when purchasing material.

A triangle calculator avoids the need to remember high school trigonometry.

### 1/5 — Useless

*2025-07-07, version 2.09*

Needs updating!!! White text on white background. Impossible to use!

### 5/5 — A great(!) alternative to that other woodworking calculator

*2025-06-14, version 2.09*

This has the essential functionality that I need to streamline basic fraction math. It also has a handy angle calculator. And, it is NOT a subscription app!!

### 4/5 — Glitch

*2025-02-26, version 2.09*

Never a problem until now. I used to see the numerals displayed just above the keyboard and now I don’t see anything until I press the equal key. I then get the sequence of numbers at the top of the screen. Recently updated my iPhone 13 to 18.3.1

### 5/5 — Not just fractions … WOODWORKING fractions! And more!

*2022-11-24, version 2.05*

I love this app. Took me a minute to figure out some of the features, like the button to convert decimals to fractions and visa versa. But once I understood that, this became my every day app for the shop. 

I use it at the hardwood seller to calculate board feet too. 

The only function I never use is the Tape function, still haven’t figured that out even after reading the help.  Would love to see a golden ratio calculator and/or a very simple notebook in its place. 

But even without the tape feature, I’ll give it 5 stars.

### 1/5 — Stop asking for reviews

### 5/5 — Does what it’s supposed to

*2020-04-08, version 2.05*
